+# Fuzzer for libmediadrm
+
+## Plugin Design Considerations
+The fuzzer plugin for libmediadrm is designed based on the understanding of the
+library 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.
+
+libmediadrm supports the following parameters:
+1. Security Level (parameter name: `securityLevel`)
+2. Mime Type (parameter name: `mimeType`)
+3. Key Type (parameter name: `keyType`)
+4. Crypto Mode (parameter name: `cryptoMode`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `securityLevel` | 0.`DrmPlugin::kSecurityLevelUnknown` 1.`DrmPlugin::kSecurityLevelMax` 2.`DrmPlugin::kSecurityLevelSwSecureCrypto` 3.`DrmPlugin::kSecurityLevelSwSecureDecode`  4.`DrmPlugin::kSecurityLevelHwSecureCrypto` 5.`DrmPlugin::kSecurityLevelHwSecureDecode` 6.`DrmPlugin::kSecurityLevelHwSecureAll`| Value obtained from FuzzedDataProvider in the range 0 to 6|
+| `mimeType` | 0.`video/mp4` 1.`video/mpeg` 2.`video/x-flv` 3.`video/mj2` 4.`video/3gp2` 5.`video/3gpp` 6.`video/3gpp2` 7.`audio/mp4` 8.`audio/mpeg` 9.`audio/aac` 10.`audio/3gp2` 11.`audio/3gpp` 12.`audio/3gpp2` 13.`video/unknown`| Value obtained from FuzzedDataProvider in the range 0 to 13|
+| `keyType` | 0.`DrmPlugin::kKeyType_Offline` 1.`DrmPlugin::kKeyType_Streaming` 2.`DrmPlugin::kKeyType_Release` | Value obtained from FuzzedDataProvider in the range 0 to 2|
+| `cryptoMode` | 0.`CryptoPlugin::kMode_Unencrypted` 1.`CryptoPlugin::kMode_AES_CTR` 2.`CryptoPlugin::kMode_AES_WV` 3.`CryptoPlugin::kMode_AES_CBC` | Value obtained from FuzzedDataProvider in the range 0 to 3|
+
+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 drm module.
+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.
+
+## Build
+
+This describes steps to build mediadrm_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) mediadrm_fuzzer
+```
+#### Steps to run
+Create a directory CORPUS_DIR
+```
+  $ adb shell mkdir CORPUS_DIR
+```
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/${TARGET_ARCH}/mediadrm_fuzzer/mediadrm_fuzzer CORPUS_DIR
+```

+# Fuzzer for writers
+
+## Table of contents
+   [libwriterfuzzerbase](#WriterFuzzerBase)
+
+# <a name="WriterFuzzerBase"></a> Fuzzer for libwriterfuzzerbase
+All the writers have a common API - creating a writer, adding a source for
+all the tracks, etc. These common APIs have been abstracted in a base class
+called `WriterFuzzerBase` to ensure code is reused between fuzzer plugins.
+
+## Plugin Design Considerations
+The fuzzer plugin for writers is designed based on the understanding of the
+writer 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.
+
+Fuzzer for writers supports the following parameters:
+1. Track Mime (parameter name: `mime`)
+2. Channel Count (parameter name: `channel-count`)
+3. Sample Rate (parameter name: `sample-rate`)
+4. Frame Height (parameter name: `height`)
+5. Frame Width (parameter name: `width`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `mime` | 0. `audio/3gpp` 1. `audio/amr-wb` 2. `audio/vorbis` 3. `audio/opus` 4. `audio/mp4a-latm` 5. `video/avc` 6. `video/hevc` 7. `video/mp4v-es` 8. `video/3gpp` 9. `video/x-vnd.on2.vp8` 10. `video/x-vnd.on2.vp9` | All the bits of 2nd byte of data for first track and 11th byte of data for second track (if present) modulus 10 |
+| `channel-count` | In the range `0 to INT32_MAX` | All the bits of 3rd byte to 6th bytes of data if first track is audio and 12th to 15th bytes of data if second track is audio |
+| `sample-rate` | In the range `1 to INT32_MAX` | All the bits of 7th byte to 10th bytes of data if first track is audio and 16th to 19th bytes of data if second track is audio |
+| `height` | In the range `0 to INT32_MAX` | All the bits of 3rd byte to 6th bytes of data if first track is video and 12th to 15th bytes of data if second track is video |
+| `width` | In the range `0 to INT32_MAX` | All the bits of 7th byte to 10th bytes of data if first track is video and 16th to 19th bytes of data if second track is video |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+##### Maximize utilization of input data
+The plugin divides the entire input data into frames based on frame markers.
+If no frame marker is found then the entire input data is treated as single frame.
+
+This ensures that the plugin tolerates any kind of input (huge,
+malformed, etc) and thereby increasing the chance of identifying vulnerabilities.
