+     * <p>This control is primarily intended to help camera applications with no support for
+     * multi-window modes to work correctly on devices where multi-window scenarios are
+     * unavoidable, such as foldables or other devices with variable display geometry or more
+     * free-form window placement (such as laptops, which often place portrait-orientation apps
+     * in landscape with pillarboxing).</p>
+     * <p>If supported, the default value is <code>ROTATE_AND_CROP_AUTO</code>, which allows the camera API
+     * to enable backwards-compatibility support for applications that do not support resizing
+     * / multi-window modes, when the device is in fact in a multi-window mode (such as inset
+     * portrait on laptops, or on a foldable device in some fold states).  In addition,
+     * <code>ROTATE_AND_CROP_NONE</code> and <code>ROTATE_AND_CROP_90</code> will always be available if this control
+     * is supported by the device.  If not supported, devices API level 30 or higher will always
+     * list only <code>ROTATE_AND_CROP_NONE</code>.</p>
+     * <p>When <code>CROP_AUTO</code> is in use, and the camera API activates backward-compatibility mode,
+     * several metadata fields will also be parsed differently to ensure that coordinates are
+     * correctly handled for features like drawing face detection boxes or passing in
+     * tap-to-focus coordinates.  The camera API will convert positions in the active array
+     * coordinate system to/from the cropped-and-rotated coordinate system to make the
+     * operation transparent for applications.  The following controls are affected:</p>
+     * <ul>
+     * <li>ACAMERA_CONTROL_AE_REGIONS</li>
+     * <li>ACAMERA_CONTROL_AF_REGIONS</li>
+     * <li>ACAMERA_CONTROL_AWB_REGIONS</li>
+     * <li>android.statistics.faces</li>
+     * </ul>
+     * <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
+     * outputs for the following parameters:</p>
+     * <ul>
+     * <li>Sensor active array: <code>2000x1500</code></li>
+     * <li>Crop region: top-left: <code>(500, 375)</code>, size: <code>(1000, 750)</code> (4:3 aspect ratio)</li>
+     * <li>Output streams: YUV <code>640x480</code> and YUV <code>1280x720</code></li>
+     * <li><code>ROTATE_AND_CROP_90</code></li>

+     * <p><img alt="Effect of ROTATE_AND_CROP_90" src="../images/camera2/metadata/android.scaler.rotateAndCrop/crop-region-rotate-90-43-ratio.png" /></p>
+     * <p>With these settings, the regions of the active array covered by the output streams are:</p>
+     * <ul>
+     * <li>640x480 stream crop: top-left: <code>(219, 375)</code>, size: <code>(562, 750)</code></li>

+#### 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://drive.google.com/drive/folders/1Z9nCIRB6pGLvb5mPkF8BURa5Nc6cY9pY). Push these files into device for testing.
+Download extractor folder and push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push extractor /data/local/tmp/
+```
+
+usage: ExtractorUnitTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/ExtractorUnitTest -P /data/local/tmp/extractor/

+          device or "devicePort".

+          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.

+#### AMR-NB Encoder :
+The Amr-Nb Encoder Test Suite validates the amrnb encoder available in libstagefright.
+
+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://drive.google.com/drive/folders/13cM4tAaVFrmr-zGFqaAzFBbKs75pnm9b). Push these files into device for testing.
+Download amr-nb_encoder folder and push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push amr-nb_encoder/. /data/local/tmp/
+```
+
+usage: AmrnbEncoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrnbEncoderTest -P /data/local/tmp/
+```

+#### 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://drive.google.com/drive/folders/13cM4tAaVFrmr-zGFqaAzFBbKs75pnm9b). Push these files into device for testing.
+Download amr-wb_encoder folder and push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push amr-wb_encoder/. /data/local/tmp/
+```
+
+usage: AmrwbEncoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/AmrwbEncoderTest -P /data/local/tmp/
+```

+## 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://drive.google.com/drive/folders/13cM4tAaVFrmr-zGFqaAzFBbKs75pnm9b).
+Download Mpeg4H263Decoder folder and push all the files in this folder to /data/local/tmp/ on the 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/
+```

+#### 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://drive.google.com/drive/folders/13cM4tAaVFrmr-zGFqaAzFBbKs75pnm9b). Push these files into device for testing.
+Download mp3 folder and push all the files in this folder to /data/local/tmp/ on the device.
+```
+adb push mp3/. /data/local/tmp/
+```
+
+usage: Mp3DecoderTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/Mp3DecoderTest -P /data/local/tmp/
