+     * <p>When <code>CROP_AUTO</code> is in use, and the camera API activates backward-compatibility mode,

+     * correctly handled for features like drawing face detection boxes or passing in

+     * <li>ACAMERA_CONTROL_AF_REGIONS</li>

+     * <p>Capture results will contain the actual value selected by the API;
+     * <code>ROTATE_AND_CROP_AUTO</code> will never be seen in a capture result.</p>
+     * <p>Applications can also select their preferred cropping mode, either to opt out of the
+     * backwards-compatibility treatment, or to use the cropping feature themselves as needed.
+     * In this case, no coordinate translation will be done automatically, and all controls
+     * will continue to use the normal active array coordinates.</p>
+     * <p>Cropping and rotating is done after the application of digital zoom (via either
+     * ACAMERA_SCALER_CROP_REGION or ACAMERA_CONTROL_ZOOM_RATIO), but before each individual
+     * output is further cropped and scaled. It only affects processed outputs such as
+     * YUV, PRIVATE, and JPEG.  It has no effect on RAW outputs.</p>
+     * <p>When <code>CROP_90</code> or <code>CROP_270</code> are selected, there is a significant loss to the field of
+     * view. For example, with a 4:3 aspect ratio output of 1600x1200, <code>CROP_90</code> will still
+     * produce 1600x1200 output, but these buffers are cropped from a vertical 3:4 slice at the
+     * center of the 4:3 area, then rotated to be 4:3, and then upscaled to 1600x1200.  Only
+     * 56.25% of the original FOV is still visible.  In general, for an aspect ratio of <code>w:h</code>,
+     * the crop and rotate operation leaves <code>(h/w)^2</code> of the field of view visible. For 16:9,
+     * this is ~31.6%.</p>
+     * <p>As a visual example, the figure below shows the effect of <code>ROTATE_AND_CROP_90</code> on the

+## Media Testing ##
+---
+#### Extractor :
+The Extractor Test Suite validates the extractors available in the device.
+
+Run the following steps to build the test suite:
+```
+m ExtractorUnitTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/ExtractorUnitTest/ExtractorUnitTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/ExtractorUnitTest/ExtractorUnitTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/extractors/tests/extractor.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push extractor /data/local/tmp/
+```
+
+usage: ExtractorUnitTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/ExtractorUnitTest -P /data/local/tmp/extractor/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest ExtractorUnitTest -- --enable-module-dynamic-download=true
+```

+          consists in a list of elements each describing pre/post proecessor settings for a given
+          device or "devicePort".
+          Each devicePort element has a "type" attribute corresponding to the device type (e.g.
+          speaker, bus), an "address" attribute corresponding to the device address and contains a
+          list of "apply" elements indicating one effect to apply.
+          If the device is a source, only pre processing effects are expected, if the
+          device is a sink, only post processing effects are expected.
+          The effect to apply is designated by its name in the "effects" elements.
+          The effect will be enabled by default and the audio framework will automatically add
+          and activate the effect if the given port is involved in an audio patch.
+          If the patch is "HW", the effect must be HW accelerated.

-A general purpose lookup utility that defines a mapping between X and Y as a
-continuous set of line segments with shared (x, y) end-points.
-The (x, y) points must be added in order, monotonically increasing in both x and y;
-a log warning is emitted if this does not happen (See general usage notes below).
-
-A limited history of (x, y) points is kept for space reasons (See general usage notes).
-
-In AudioFlinger, we use the LinearMap to associate track frames to
-sink frames.  When we want to obtain a client track timestamp, we first
-get a timestamp from the sink.  The sink timestamp's position (mPosition)
-corresponds to the sink frames written. We use LinearMap to figure out which track frame
-the sink frame corresponds to. This allows us to substitute a track frame for the
-the sink frame (keeping the mTime identical) and return that timestamp back to the client.
-
-The method findX() can be used to retrieve an x value from a given y value and is
-used for timestamps, similarly for findY() which is provided for completeness.
-
-We update the (track frame, sink frame) points in the LinearMap each time we write data
-to the sink by the AudioFlinger PlaybackThread (MixerThread).
-
-
-AudioFlinger Timestamp Notes:
-
-1) Example: Obtaining a track timestamp during playback.  In this case, the LinearMap
-looks something like this:
-
-Track Frame    Sink Frame
-(track start)
-0              50000  (track starts here, the sink may already be running)
-1000           51000
-2000           52000
-
-When we request a track timestamp, we call the sink getTimestamp() and get for example
-mPosition = 51020.  Using the LinearMap, we find we have played to track frame 1020.
-We substitute the sink mPosition of 51020 with the track position 1020,
-and return that timestamp to the app.
-
-2) Example: Obtaining a track timestamp duing pause. In this case, the LinearMap
-looks something like this:
-
-Track Frame    Sink Frame
-... (some time has gone by)
-15000          30000
-16000          31000
-17000          32000
-(pause here)
-(suppose we call sink getTimestamp() here and get sink mPosition = 31100; that means
-        we have played to track frame 16100.  The track timestamp mPosition will
-        continue to advance until the sink timestamp returns a value of mPosition
-        greater than 32000, corresponding to track frame 17000 when the pause was called).
-17000          33000
-17000          34000
-...
-
-3) If the track underruns, it appears as if a pause was called on that track.
-
-4) If there is an underrun in the HAL layer, then it may be possible that
-the sink getTimestamp() will return a value greater than the number of frames written
-(it should always be less). This should be rare, if not impossible by some
-HAL implementations of the sink getTimestamp. In that case, timing is lost
-and we will return the most recent track frame written.
-
-5) When called with no points in the map, findX() returns the start value (default 0).
-This is consistent with starting after a stop() or flush().
-
-6) Resuming after Track standby will be similar to coming out of pause, as the HAL ensures
-framesWritten() and getTimestamp() are contiguous for non-offloaded/direct tracks.
-
-7) LinearMap works for different speeds and sample rates as it uses
-linear interpolation. Since AudioFlinger only updates speed and sample rate
-exactly at the sample points pushed into the LinearMap, the returned values
-from findX() and findY() are accurate regardless of how many speed or sample
-rate changes are made, so long as the coordinate looked up is within the
-sample history.
-
-General usage notes:
-
-1) In order for the LinearMap to work reliably, you cannot look backwards more
-than the size of its circular buffer history, set upon creation (typically 16).
-If you look back further, the position is extrapolated either from a passed in
-extrapolation parameter or from the oldest line segment.
-
-2) Points must monotonically increase in x and y. The increment between adjacent
-points cannot be greater than signed 32 bits. Wrap in the x, y coordinates are supported,
-since we use differences in our computation.
-
-3) If the frame data is discontinuous (due to stop or flush) call reset() to clear
-the sample counter.
-
-4) If (x, y) are not strictly monotonic increasing, i.e. (x2 > x1) and (y2 > y1),
-then one or both of the inverses y = f(x) or x = g(y) may have multiple solutions.
-In that case, the most recent solution is returned by findX() or findY().  We
-do not warn if (x2 == x1) or (y2 == y1), but we do logcat warn if (x2 < x1) or
-(y2 < y1).
-
-5) Due to rounding it is possible x != findX(findY(x)) or y != findY(findX(y))
-even when the inverse exists. Nevertheless, the values should be close.

-/**
- * The Visualizer class enables application to retrieve part of the currently playing audio for
- * visualization purpose. It is not an audio recording interface and only returns partial and low
- * quality audio content. However, to protect privacy of certain audio data (e.g voice mail) the use
- * of the visualizer requires the permission android.permission.RECORD_AUDIO.
- * The audio session ID passed to the constructor indicates which audio content should be
- * visualized:
- * - If the session is 0, the audio output mix is visualized
- * - If the session is not 0, the audio from a particular MediaPlayer or AudioTrack
- *   using this audio session is visualized
- * Two types of representation of audio content can be captured:
- * - Waveform data: consecutive 8-bit (unsigned) mono samples by using the getWaveForm() method
- * - Frequency data: 8-bit magnitude FFT by using the getFft() method
- *
- * The length of the capture can be retrieved or specified by calling respectively
- * getCaptureSize() and setCaptureSize() methods. Note that the size of the FFT
- * is half of the specified capture size but both sides of the spectrum are returned yielding in a
- * number of bytes equal to the capture size. The capture size must be a power of 2 in the range
- * returned by getMinCaptureSize() and getMaxCaptureSize().
- * In addition to the polling capture mode, a callback mode is also available by installing a
- * callback function by use of the setCaptureCallBack() method. The rate at which the callback
- * is called as well as the type of data returned is specified.
- * Before capturing data, the Visualizer must be enabled by calling the setEnabled() method.
- * When data capture is not needed any more, the Visualizer should be disabled.

+ * MediaMetrics Item
+ *
+ * The MediaMetrics Item allows get/set operations and recording to the service.
+ *
+ * The MediaMetrics LogItem is a faster logging variant. It allows set operations only,
+ * and then recording to the service.
+ *
+ * The Byte String format is as follows:
+ *
+ * For Java
+ *  int64 corresponds to long
+ *  int32, uint32 corresponds to int
+ *  uint16 corresponds to char
+ *  uint8, int8 corresponds to byte
+ *
+ * For items transmitted from Java, uint8 and uint32 values are limited
+ * to INT8_MAX and INT32_MAX.  This constrains the size of large items
+ * to 2GB, which is consistent with ByteBuffer max size. A native item
+ * can conceivably have size of 4GB.
+ *
+ * Physical layout of integers and doubles within the MediaMetrics byte string
+ * is in Native / host order, which is usually little endian.
+ *
+ * Note that primitive data (ints, doubles) within a Byte String has
+ * no extra padding or alignment requirements, like ByteBuffer.
+ *
+ * -- begin of item
+ * -- begin of header
+ * (uint32) item size: including the item size field
+ * (uint32) header size, including the item size and header size fields.
+ * (uint16) version: exactly 0
+ * (uint16) key size, that is key strlen + 1 for zero termination.
+ * (int8)+ key, a string which is 0 terminated (UTF-8).
+ * (int32) pid
+ * (int32) uid
+ * (int64) timestamp
+ * -- end of header
+ * -- begin body
+ * (uint32) number of properties
+ * -- repeat for number of properties
+ *     (uint16) property size, including property size field itself
+ *     (uint8) type of property
+ *     (int8)+ key string, including 0 termination
+ *      based on type of property (given above), one of:
+ *       (int32)
+ *       (int64)
+ *       (double)
+ *       (int8)+ for TYPE_CSTRING, including 0 termination
+ *       (int64, int64) for rate
+ * -- end body
+ * -- end of item
+ *
+ * The Byte String format must match MediaMetrics.java.

-     *                     (TODO: Check direct output after flags can be used in Java AudioTrack.)
-     * format:             Audio format. For mixed tracks, any PCM format supported by server is OK.
-     *                     For direct and offloaded tracks, the possible format(s) depends on the

-     *                     (TODO: How can we check whether a format is supported?)
-     * channelMask:        Channel mask, such that audio_is_output_channel(channelMask) is true.
-     * cbf:                Callback function. If not null, this function is called periodically
-     *                     to provide new data and inform of marker, position updates, etc.
-     * user:               Context for use by the callback receiver.
-     * frameCount:         Minimum size of track PCM buffer in frames. This defines the
-     *                     application's contribution to the latency of the track.
-     *                     The actual size selected by the JAudioTrack could be larger if the
-     *                     requested size is not compatible with current audio HAL configuration.
-     *                     Zero means to use a default value.
-     * sessionId:          Specific session ID, or zero to use default.
-     * pAttributes:        If not NULL, supersedes streamType for use case selection.
-     * maxRequiredSpeed:   For PCM tracks, this creates an appropriate buffer size that will allow

-     *                     current time for the timestamp.
-     *                     If WOULD_BLOCK is returned, the timestamp is still

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the

+#### AMR-NB Decoder :
+The Amr-Nb Decoder Test Suite validates the amrnb decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrnbDecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/AmrnbDecoderTest/AmrnbDecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrnbDecoderTest/AmrnbDecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://drive.google.com/drive/folders/13cM4tAaVFrmr-zGFqaAzFBbKs75pnm9b). Push these files into device for testing.
+Download amr-nb folder and push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push amr-nb/. /data/local/tmp/
+```
+
+usage: AmrnbDecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrnbDecoderTest -P /data/local/tmp/
+```

+
+Run the following steps to build the test suite:
+```
+m AmrnbEncoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/AmrnbEncoderTest/AmrnbEncoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrnbEncoderTest/AmrnbEncoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/amrnb/enc/test/AmrnbEncoderTest.zip). Download, unzip and push these files into device for testing.

+# Fuzzer for libstagefright_amrnbdec decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for AMR-NB is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on
+incoming data. This ensures more code paths are reached by the fuzzer.
+
+AMR-NB supports the following parameters:
+1. Stream format (parameter name: `input_format`)
+2. 3GPP frame type (parameter name: `frame_type`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `input_format` | 0. `MIME_IETF` 1. `IF2` | Bit 0 (LSB) of 1st byte of data. |
+| `frame_type`   | 0. `AMR_475` 1. `AMR_515` 2. `AMR_59` 3. `AMR_67`  4. `AMR_74` 5. `AMR_795` 6. `AMR_102` 7. `AMR_122`  | Bits 3, 4 and 5 of 1st byte of data. |
+
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec using a loop.
+If the decode operation was successful, the input is advanced by the frame size
+which is based on `input_format` and `frame_type` selected.
+If the decode operation was un-successful, the input is still advanced by frame size so
+that the fuzzer can proceed to feed the next frame.
+
+This ensures that the plugin tolerates any kind of input (empty, huge,
+malformed, etc) and doesnt `exit()` on any input and thereby increasing the
+chance of identifying vulnerabilities.
+

+## Media Testing ##
+---
+#### AMR-WB Decoder :
+The Amr-Wb Decoder Test Suite validates the amrwb decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrwbDecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/AmrwbDecoderTest/AmrwbDecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrwbDecoderTest/AmrwbDecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/amrwb/test/AmrwbDecoderTest.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push AmrwbDecoderTestRes/. /data/local/tmp/
+```
+
+usage: AmrwbDecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrwbDecoderTest -P /data/local/tmp/AmrwbDecoderTestRes/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest AmrwbDecoderTest -- --enable-module-dynamic-download=true
+```

+## Media Testing ##
+---
+#### AMR-WB Encoder :
+The Amr-Wb Encoder Test Suite validates the amrwb encoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m AmrwbEncoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/AmrwbEncoderTest/AmrwbEncoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/AmrwbEncoderTest/AmrwbEncoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/amrwbenc/test/AmrwbEncoderTest.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push AmrwbEncoderTestRes/. /data/local/tmp/
+```
+
+usage: AmrwbEncoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrwbEncoderTest -P /data/local/tmp/AmrwbEncoderTestRes/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest AmrwbEncoderTest -- --enable-module-dynamic-download=true
+```

+## Media Testing ##
+---
+#### Mpeg4H263Decoder :
+The Mpeg4H263Decoder Test Suite validates the Mpeg4 and H263 decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m Mpeg4H263DecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/Mpeg4H263DecoderTest/Mpeg4H263DecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/Mpeg4H263DecoderTest/Mpeg4H263DecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/m4v_h263/dec/test/Mpeg4H263Decoder.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push Mpeg4H263Decoder /data/local/tmp/
+```
+
+usage: Mpeg4H263DecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/Mpeg4H263DecoderTest -P /data/local/tmp/Mpeg4H263Decoder/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest Mpeg4H263DecoderTest -- --enable-module-dynamic-download=true
+```

+## Media Testing ##
+---
+
+#### Mpeg4H263Encoder :
+The Mpeg4H263Encoder Test Suite validates the Mpeg4 and H263 encoder available in libstagefright.
+Run the following steps to build the test suite:
+```
+m Mpeg4H263EncoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/Mpeg4H263EncoderTest/Mpeg4H263EncoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/Mpeg4H263EncoderTest/Mpeg4H263EncoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/codecs/m4v_h263/enc/test/Mpeg4H263Encoder.zip ) Download, unzip and push these files into device for testing.
+
+```
+adb push Mpeg4H263Encoder/. /data/local/tmp/
+```
+
+usage: Mpeg4H263EncoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/Mpeg4H263EncoderTest -P /data/local/tmp/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest Mpeg4H263EncoderTest -- --enable-module-dynamic-download=true
+```

+## Media Testing ##
+---
+#### Mp3Decoder :
+The Mp3Decoder Test Suite validates the mp3decoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m Mp3DecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/Mp3DecoderTest/Mp3DecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/Mp3DecoderTest/Mp3DecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/mp3dec/test/Mp3DecoderTest.zip). Download, unzip and push these files into device for testing.
+
+```
+adb push Mp3DecoderTestRes/. /data/local/tmp/
+```
+
+usage: Mp3DecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/Mp3DecoderTest -P /data/local/tmp/Mp3DecoderTestRes/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest Mp3DecoderTest -- --enable-module-dynamic-download=true
+```

+## Media Testing ##
+---
+#### FlacDecoder :
+The FlacDecoder Test Suite validates the FlacDecoder available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m FlacDecoderTest
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/FlacDecoderTest/FlacDecoderTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/FlacDecoderTest/FlacDecoderTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/flac/dec/test/FlacDecoder.zip).
+Download, unzip and push these files into device for testing.
+
+```
+adb push FlacDecoder /data/local/tmp/
+```
+
+usage: FlacDecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/FlacDecoderTest -P /data/local/tmp/FlacDecoder/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest FlacDecoderTest -- --enable-module-dynamic-download=true
+```

+#### ID3 Test :
+The ID3 Test Suite validates the ID3 parser available in libstagefright.
+
+Run the following command in the id3 folder to build the test suite:
+```
+m ID3Test
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+```
+adb push ${OUT}/data/nativetest64/ID3Test/ID3Test /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/ID3Test/ID3Test /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/id3/test/ID3Test.zip ).
+Download, unzip and push these files into device for testing.
+
+```
+adb push ID3Test /data/local/tmp/
+```
+
+usage: ID3Test -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/ID3Test -P /data/local/tmp/ID3/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest ID3Test -- --enable-module-dynamic-download=true
+```

+#### Writer :
+The Writer Test Suite validates the writers available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+mmm frameworks/av/media/libstagefright/tests/writer/
+```
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+
+adb push ${OUT}/data/nativetest64/writerTest/writerTest /data/local/tmp/
+
+To test 32-bit binary push binaries from nativetest.
+
+adb push ${OUT}/data/nativetest/writerTest/writerTest /data/local/tmp/
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/tests/writer/writerTestRes.zip).
+Download and extract the folder. Push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push writerTestRes /data/local/tmp/
+```
+
+usage: writerTest -P \<path_to_res_folder\>
+```
+adb shell /data/local/tmp/writerTest -P /data/local/tmp/

+# Benchmark tests
+
+Benchmark app analyses the time taken by MediaCodec, MediaExtractor and MediaMuxer for given set of inputs. It is used to benchmark these modules on android devices.
+Benchmark results are emitted to logcat.
+
+This page describes steps to run the NDK and SDK layer test.
+
+Run the following steps to build the test suite:
+```
+mmm frameworks/av/media/tests/benchmark/
+```
+
+# NDK
+
+To run the test suite for measuring performance of the native layer, follow the following steps:
+
+The binaries will be created in the following path : $OUT/data/nativetest64/
+
+adb push $OUT/data/nativetest64/* /data/local/tmp/
+
+Eg. adb push $OUT/data/nativetest64/extractorTest/extractorTest /data/local/tmp/
+
+To run the binary, follow the commands mentioned below under each module.
+
+The resource file for the tests is taken from [here](https://drive.google.com/open?id=1ghMr17BBJ7n0pqbm7oREiTN_MNemJUqy)
+
+Download the MediaBenchmark.zip file, unzip and push it to /data/local/tmp/ on the device.
+
+```
+unzip MediaBenchmark.zip
+adb push MediaBenchmark /data/local/tmp
+```
+
+## Extractor
+
+The test extracts elementary stream and benchmarks the extractors available in NDK.
+
+The resource files are assumed to be at /data/local/tmp/MediaBenchmark/res/. You can use a different location, but you have to modify the rest of the instructions to replace /data/local/tmp/MediaBenchmark/res/ with wherever you chose to put the files.
+
+The path to these files on the device is required to be given for the test.
+
+```
+adb shell /data/local/tmp/extractorTest -P /data/local/tmp/MediaBenchmark/res/
+```
+
+## Decoder
+
+The test decodes input stream and benchmarks the decoders available in NDK.
+
+Setup steps are same as extractor.
+
+```
+adb shell /data/local/tmp/decoderTest -P /data/local/tmp/MediaBenchmark/res/
+```
+
+## Muxer
+
+The test muxes elementary stream and benchmarks the muxers available in NDK.
+
+Setup steps are same as extractor.
+
+```
+adb shell /data/local/tmp/muxerTest -P /data/local/tmp/MediaBenchmark/res/
+```
+
+## Encoder
+
+The test encodes input stream and benchmarks the encoders available in NDK.
+
+Setup steps are same as extractor.
+
+```
+adb shell /data/local/tmp/encoderTest -P /data/local/tmp/MediaBenchmark/res/
+```
+
+# SDK
+
+To run the test suite for measuring performance of the SDK APIs, follow the following steps:
+
+The apk will be created at the following path:
+$OUT/testcases/MediaBenchmarkTest/arm64/
+
+To get the resorce files for the test follow instructions given in [NDK](#NDK)
+
+For installing the apk, run the command:
+```
+adb install -f -r $OUT/testcases/MediaBenchmarkTest/arm64/MediaBenchmarkTest.apk
+```
+
+For running all the tests, run the command:
+```
+adb shell am instrument -w -r -e package com.android.media.benchmark.tests com.android.media.benchmark/androidx.test.runner.AndroidJUnitRunner
+```
+
+## Extractor
+
+The test extracts elementary stream and benchmarks the extractors available in SDK.
+```
+adb shell am instrument -w -r -e class 'com.android.media.benchmark.tests.ExtractorTest' com.android.media.benchmark/androidx.test.runner.AndroidJUnitRunner
+```
+
+## Decoder
+
+The test decodes input stream and benchmarks the decoders available in SDK.
+```
+adb shell am instrument -w -r -e class 'com.android.media.benchmark.tests.DecoderTest' com.android.media.benchmark/androidx.test.runner.AndroidJUnitRunner
+```
+
+## Muxer
+
+The test muxes elementary stream and benchmarks different writers available in SDK.
+```
+adb shell am instrument -w -r -e class 'com.android.media.benchmark.tests.MuxerTest' com.android.media.benchmark/androidx.test.runner.AndroidJUnitRunner
+```
+
+## Encoder
+
+The test encodes input stream and benchmarks the encoders available in SDK.
+```
+adb shell am instrument -w -r -e class 'com.android.media.benchmark.tests.EncoderTest' com.android.media.benchmark/androidx.test.runner.AndroidJUnitRunner
+```
+
+# Codec2
+To run the test suite for measuring performance of the codec2 layer, follow the following steps:
+
+The 32-bit binaries will be created in the following path : ${OUT}/data/nativetest/
+The 64-bit binaries will be created in the following path : ${OUT}/data/nativetest64/
+
+To test 64-bit binary push binaries from nativetest64.
+adb push $(OUT)/data/nativetest64/* /data/local/tmp/
+Eg. adb push $(OUT)/data/nativetest64/C2DecoderTest/C2DecoderTest /data/local/tmp/
+
+To test 32-bit binary push binaries from nativetest.
+adb push $(OUT)/data/nativetest/* /data/local/tmp/
+Eg. adb push $(OUT)/data/nativetest/C2DecoderTest/C2DecoderTest /data/local/tmp/
+
+To get the resource files for the test follow instructions given in [NDK](#NDK)
+
+## C2 Decoder
+
+The test decodes input stream and benchmarks the codec2 decoders available in device.
+
+Setup steps are same as [extractor](#extractor).
+
+```
+adb shell /data/local/tmp/C2DecoderTest -P /data/local/tmp/MediaBenchmark/res/
+```
+## C2 Encoder
+
+The test encodes input stream and benchmarks the codec2 encoders available in device.
+
+Setup steps are same as [extractor](#extractor).
+
+```
+adb shell /data/local/tmp/C2EncoderTest -P /data/local/tmp/MediaBenchmark/res/

-
-# audio hardware module section: contains descriptors for all audio hw modules present on the

-# For instance, "primary" corresponds to audio.primary.<device>.so.
-# The "primary" module is mandatory and must include at least one output with
-# AUDIO_OUTPUT_FLAG_PRIMARY flag.
-# Each module descriptor contains one or more output profile descriptors and zero or more
-# input profile descriptors. Each profile lists all the parameters supported by a given output
-# or input stream category.
-# The "channel_masks", "formats", "devices" and "flags" are specified using strings corresponding

-# - Optionally a "devices" section:

-#      }
-#    }
-# - one or more "gains" sections can be present in a device descriptor section.
-#   If present, they describe the capabilities of gain controllers attached to this input or
-#   output device. e.g. :
-#   <device name> {                  # <device name>: any string without space
-#     type <device type>             # <device type> e.g. AUDIO_DEVICE_OUT_SPEAKER

+ * methods in the object T at the same time.
+ * Suggested by Kevin R.
+ *
+ * EXAMPLE:
+ *
+ * // Accumulator class which is very slow, requires locking for multiple threads.
+ *
+ * class Accumulator {
+ *   int32_t value_ = 0;
+ * public:
+ *   void add(int32_t incr) {

+ *     sleep(0);  // yield
+ *     value_ = temp + incr;
+ *   }
+ *   int32_t get() { return value_; }
+ * };
+ *
+ * // We use LockWrap on Accumulator to have safe multithread access.
+ * android::mediametrics::LockWrap<Accumulator> a{}; // locked accumulator succeeds
+ *
+ * // Conversely, the following line fails:
+ * // auto a = std::make_shared<Accumulator>(); // this fails, only 50% adds atomic.
+ *
+ * constexpr size_t THREADS = 100;
+ * constexpr size_t ITERATIONS = 10;
+ * constexpr int32_t INCREMENT = 1;
+ *
+ * // Test by generating multiple threads, all adding simultaneously.
+ * std::vector<std::future<void>> threads(THREADS);
+ * for (size_t i = 0; i < THREADS; ++i) {
+ *     threads.push_back(std::async(std::launch::async, [&] {
+ *         for (size_t j = 0; j < ITERATIONS; ++j) {
+ *             a->add(INCREMENT);  // add needs locked access here.
+ *         }
+ *     }));
+ * }
+ * threads.clear();

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
