+# Fuzzer for libstagefright_g711dec decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for G711 is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+G711 supports two types of decoding:
+1. DecodeALaw
+2. DecodeMLaw
+
+These two decoder API's are fuzzed separately using g711alaw_dec_fuzzer and
+g711mlaw_dec_fuzzer respectively.
+
+##### Maximize utilization of input data
+The plugin feeds the entire input data to the codec as expected by decoder API.
+
+## Build
+
+This describes steps to build g711alaw_dec_fuzzer and g711mlaw_dec_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) g711alaw_dec_fuzzer
+  $ mm -j$(nproc) g711mlaw_dec_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some g711 files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/g711alaw_dec_fuzzer/g711alaw_dec_fuzzer CORPUS_DIR
+  $ adb shell /data/fuzz/arm64/g711mlaw_dec_fuzzer/g711mlaw_dec_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/g711alaw_dec_fuzzer/g711alaw_dec_fuzzer CORPUS_DIR
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/g711mlaw_dec_fuzzer/g711mlaw_dec_fuzzer CORPUS_DIR
+```

+# <a name="ExtractorFuzzerBase"></a> Fuzzer for libextractorfuzzerbase
+All the extractors have a common API - creating a data source, extraction
+of all the tracks, etc. These common APIs have been abstracted in a base class
+called `ExtractorFuzzerBase` to ensure code is reused between fuzzer plugins.
+
+Additionally, `ExtractorFuzzerBase` also has support for memory based buffer
+`BufferSource` since the fuzzing engine feeds data using memory buffers and
+usage of standard data source objects like FileSource, HTTPSource, etc. is
+not feasible.
+
+# <a name="mp4ExtractorFuzzer"></a> Fuzzer for libmp4extractor
+
+## Plugin Design Considerations
+The fuzzer plugin for MP4 extractor uses the `ExtractorFuzzerBase` class and
+implements only the `createExtractor` to create the MP4 extractor class.
+
+##### Maximize code coverage
+Dict file (dictionary file) is created for MP4 to ensure that the required MP4
+atoms are present in every input file that goes to the fuzzer.
+This ensures that larger code gets covered as a range of MP4 atoms will be
+present in the input data.
+
+
+## Build
+
+This describes steps to build mp4_extractor_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) mp4_extractor_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some MP4 files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/mp4_extractor_fuzzer/mp4_extractor_fuzzer CORPUS_DIR

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-
-    Rec_Y = pointer to 0th position in buffer containing luminance values
-        of type uint8.
-    y_start = value of y coordinate of type int that specifies the first
-        row of pixels to be used in the filter algorithm.
-    x_start = value of x coordinate of type int that specifies the first
-        column of pixels to be used in the filter algorithm.
-    y_blk_start = value of the y coordinate of type int that specifies the
-        row of pixels which contains the start of a block. The row
-        specified by y_blk_start+BLK_SIZE is the last row of pixels
-        that are used in the filter algorithm.
-    x_blk_start = value of the x coordinate of type int that specifies the
-        column of pixels which contains the start of a block.  The
-        column specified by x_blk_start+BLK_SIZE is the last column of
-        pixels that are used in the filter algorithm.
-    thr = value of type int that is compared to the elements in Rec_Y to
-        determine if a particular value in Rec_Y will be modified by
-        the filter or not
-    width = value of type int that specifies the width of the display
-        in pixels (or pels, equivalently).
-    max_diff = value of type int that specifies the value that may be added
-        or subtracted from the pixel in Rec_Y that is being filtered
-        if the filter algorithm decides to change that particular
-        pixel's luminance value.

- FUNCTION DESCRIPTION
-
- This function implements a motion compensated noise filter using adaptive
- weighted averaging of luminance values.  *Rec_Y contains the luminance values
- that are being filtered.
-
- The picture below depicts a 3x3 group of pixel luminance values.  The "u", "c",
- and "l" stand for "upper", "center" and "lower", respectively.  The location
- of pelc0 is specified by x_start and y_start in the 1-D array "Rec_Y" as
- follows (assuming x_start=0):
-
- location of pelc0 = [(y_start+1) * width] + x_start
-
- Moving up or down 1 row (moving from pelu2 to pelc2, for example) is done by
- incrementing or decrementing "width" elements within Rec_Y.
-
- The coordinates of the upper left hand corner of a block (not the group of
- 9 pixels depicted in the figure below) is specified by
- (y_blk_start, x_blk_start).  The width and height of the block is BLKSIZE.
- (y_start,x_start) may be specified independently of (y_blk_start, x_blk_start).
-
-    (y_start,x_start)

-    |   |   |   |
- --------------------------------------
-
- The filtering of the luminance values is achieved by comparing the 9
- luminance values to a threshold value ("thr") and then changing the
- luminance value of pelc1 if all of the values are above or all of the values
- are below the threshold.  The amount that the luminance value is changed
- depends on a weighted sum of the 9 luminance values. The position of Pelc1
- is then advanced to the right by one (as well as all of the surrounding pixels)
- and the same calculation is performed again for the luminance value of the new
- Pelc1. This continues row-wise until pixels in the last row of the block are
- filtered.

- FUNCTION DESCRIPTION
-
- This function finds the maximum and the minimum values in a square block of
- data of size BLKSIZE * BLKSIZE. The data is contained in the buffer which
- represents a 2D block of data that is larger than BLKSIZE * BLKSIZE.
- This is illustrated below.
-
-    mem loc x + 00h -> o o o o o o o o o o o o o o o o
-    mem loc x + 10h -> o o o o o X X X X X X X X o o o
-    mem loc x + 20h -> o o o o o X X X X X X X X o o o
-    mem loc x + 30h -> o o o o o X X X X X X X X o o o
-    mem loc x + 40h -> o o o o o X X X X X X X X o o o
-    mem loc x + 50h -> o o o o o X X X X X X X X o o o
-    mem loc x + 60h -> o o o o o X X X X X X X X o o o
-    mem loc x + 70h -> o o o o o X X X X X X X X o o o
-    mem loc x + 80h -> o o o o o X X X X X X X X o o o
-    mem loc x + 90h -> o o o o o o o o o o o o o o o o
-    mem loc x + A0h -> o o o o o o o o o o o o o o o o
-    mem loc x + B0h -> o o o o o o o o o o o o o o o o
-
-For illustration purposes, the diagram assumes that BLKSIZE is equal to 8
-but this is not a requirement. In this diagram, the buffer starts at
-location x but the input pointer, input_ptr, passed into this function
-would be the first row of data to be searched which is at x + 15h. The
-value of incr passed onto this function represents the amount the input_ptr
-needs to be incremented to point to the next row of data.
-
-This function compares each value in a row to the current maximum and
-minimum. After each row, input_ptr is incremented to point to the next row.
-This is repeated until all rows have been processed. When the search is
-complete the location pointed to by min_ptr contains the minimum value
-found and the location pointed to by max_ptr contains the maximum value found.

- INPUT AND OUTPUT DEFINITIONS
-
- Inputs:
-    q_block = pointer to buffer of inverse quantized DCT coefficients of type
-              int for intra-VOP mode or buffer of residual data of type int
-              for inter-VOP mode
-
- Local Stores/Buffers/Pointers Needed:
-    None
-
- Global Stores/Buffers/Pointers Needed:
-    None
-
- Outputs:
-    postmode = post processing semaphore with the vertical deblocking,
-               horizontal deblocking, and deringing bits set up accordingly
-
- Pointers and Buffers Modified:
-    None

-------------------------------------------------------------------------------
- FUNCTION DESCRIPTION
-
- This function sets up the postmode semaphore based on the contents of the
- buffer pointed to by q_block. The function starts out with the assumption
- that all entries of q_block, except for the first entry (q_block[0]), are
- zero. This case can induce horizontal and vertical blocking artifacts,
- therefore, both horizontal and vertical deblocking bits are enabled.
-
- The following conditions are tested when setting up the horizontal/vertical
- deblocking and deringing bits:
- 1. When only the elements of the top row of the B_SIZE x B_SIZE block
-    (q_block[n], n = 0,..., B_SIZE-1) are non-zero, vertical blocking artifacts
-    may result, therefore, only the vertical deblocking bit is enabled.
-    Otherwise, the vertical deblocking bit is disabled.
- 2. When only the elements of the far left column of the B_SIZE x B_SIZE block
-    (q_block[n*B_SIZE], n = 0, ..., B_SIZE-1) are non-zero, horizontal blocking
-    artifacts may result, therefore, only the horizontal deblocking bit is
-    enabled. Otherwise, the horizontal deblocking bit is disabled.
- 3. If any non-zero elements exist in positions other than q_block[0],
-    q_block[1], or q_block[B_SIZE], the deringing bit is enabled. Otherwise,
-    it is disabled.
-
- The 3 least significant bits of postmode defines vertical or horizontal
- deblocking and deringing.
-
- The valid values are shown below:
- -------------------------------------------------------
- |           Type                 | Enabled | Disabled |
- -------------------------------------------------------
- | Vertical Deblocking (Bit #0)   |    1    |     0    |
- -------------------------------------------------------
- | Horizontal Deblocking (Bit #1) |    1    |     0    |
- -------------------------------------------------------
- | Deringing (Bit #2)             |    1    |     0    |

+# Fuzzer for libstagefright_m4vh263dec decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for MPEG4/H263 is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+Dict files (dictionary files) are created for MPEG4 and H263 to ensure that the required start
+bytes are present in every input file that goes to the fuzzer.
+This ensures that decoder does not reject any input file in the first check
+
+##### 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 number of bytes consumed
+   in the decode call.
+ * If the decode operation was un-successful, the input is advanced by 1 byte 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.
+
+##### Other considerations
+ * Two fuzzer binaries - mpeg4_dec_fuzzer and h263_dec_fuzzer are generated based on the presence
+   of a flag - 'MPEG4'
+ * The number of decode calls are kept to a maximum of 100 so that the fuzzer does not timeout.
+
+## Build
+
+This describes steps to build mpeg4_dec_fuzzer and h263_dec_fuzzer binary.
+
+### Android
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) mpeg4_dec_fuzzer
+  $ mm -j$(nproc) h263_dec_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some MPEG4 or H263 files to that folder
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/mpeg4_dec_fuzzer/mpeg4_dec_fuzzer CORPUS_DIR
+  $ adb shell /data/fuzz/arm64/h263_dec_fuzzer/h263_dec_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/mpeg4_dec_fuzzer/mpeg4_dec_fuzzer CORPUS_DIR
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/h263_dec_fuzzer/h263_dec_fuzzer CORPUS_DIR
+```

+# Fuzzer for libstagefright_mp3dec decoder
+
+## Plugin Design Considerations
+The fuzzer plugin for mp3 decoder is designed based on the understanding of the
+codec and tries to achieve the following:
+
+##### Maximize code coverage
+
+This fuzzer makes use of the following config parameters:
+1. Equalizer type (parameter name: `equalizerType`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `equalizerType` | 0. `flat ` 1. `bass_boost ` 2. `rock ` 3. `pop ` 4. `jazz ` 5. `classical ` 6. `talk ` 7. `flat_ ` | Bits 0, 1 and 2 of first byte of input stream |
+| `crcEnabled` | 0. `false ` 1. `true `| Bit 0 of second byte of input stream |
+
+##### 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 number
+   of bytes used by the decoder.
+ * If the decode operation was un-successful, the input is advanced by 1 byte
+   till it reaches a valid frame or end of stream.
+
+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 mp3_dec_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) mp3_dec_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR and copy some mp3 files to that folder.
+Push this directory to device.
+
+To run on device
+```
+  $ adb sync data
+  $ adb shell /data/fuzz/arm64/mp3_dec_fuzzer/mp3_dec_fuzzer CORPUS_DIR
+```
+To run on host
+```
+  $ $ANDROID_HOST_OUT/fuzz/x86_64/mp3_dec_fuzzer/mp3_dec_fuzzer CORPUS_DIR
+```

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

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

+#### Mpeg2TS Unit Test :
+The Mpeg2TS Unit Test Suite validates the functionality of the libraries present in Mpeg2TS.
+
+Run the following steps to build the test suite:
+```
+mmm frameworks/av/media/libstagefright/mpeg2ts/test/
+```
+
+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/Mpeg2tsUnitTest/Mpeg2tsUnitTest /data/local/tmp/
+
+To test 32-bit binary push binaries from nativetest.
+
+adb push ${OUT}/data/nativetest/Mpeg2tsUnitTest/Mpeg2tsUnitTest /data/local/tmp/
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/mpeg2ts/test/Mpeg2tsUnitTest.zip ).
+Download, unzip and push these files into device for testing.
+
+```
+adb push Mpeg2tsUnitTestRes/. /data/local/tmp/
+```
+
+usage: Mpeg2tsUnitTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/Mpeg2tsUnitTest -P /data/local/tmp/Mpeg2tsUnitTestRes/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest Mpeg2tsUnitTest -- --enable-module-dynamic-download=true
+```

+#### ESDS Unit Test :
+The ESDS Unit Test Suite validates the ESDS class available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m ESDSTest
+```
+
+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/ESDSTest/ESDSTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/ESDSTest/ESDSTest /data/local/tmp/
+```
+
+The resource file for the tests is taken from [here](https://storage.googleapis.com/android_media/frameworks/av/media/libstagefright/tests/ESDS/ESDSTestRes-1.0.zip)
+Download, unzip and push these files into device for testing.
+
+```
+adb push ESDSTestRes /data/local/tmp/
+```
+
+usage: ESDSTest -P \<path_to_folder\>
+```
+adb shell /data/local/tmp/ESDSTest -P /data/local/tmp/ESDSTestRes/
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest ESDSTest -- --enable-module-dynamic-download=true
+```

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

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

+# Analysis
+
+The benchmark results are stored in a CSV file which can be used for analysis. These results are stored in following format:
+<app directory>/<module_name>.<timestamp>.csv
+
+Note: This timestamp is in nano seconds and will change based on current system time.
+
+To find the location of the CSV file, look for the path in logs. Example log below -
+
+```
+com.android.media.benchmark D/DecoderTest: Saving Benchmark results in: /storage/emulated/0/Android/data/com.android.media.benchmark/files/Decoder.1587732395387.csv
+```
+
+This file can be pulled from the device using "adb pull" command.
+```
+adb pull /storage/emulated/0/Android/data/com.android.media.benchmark/files/Decoder.1587732395387.csv ./Decoder.1587732395387.csv
+```
+
+## CSV Columns
+
+Following columns are available in CSV.
+
+Note: All time values are in nano seconds
+
+1. **currentTime** : The time recorded at the creation of the stats. This may be used to estimate time between consecutive test clips.
+
+2. **fileName**: The file being used as an input for the benchmark test.
+
+3. **operation**: The current operation on the input test vector i.e. Extract/Mux/Encode/Decode.
+
+4. **NDK/SDK**: The target APIs i.e. AMedia vs Media calls for the operation being performed.
+
+5. **sync/async**: This is specific to MediaCodec objects (i.e. Encoder and Decoder). It specifies the mode in which MediaCodec APIs are working. For async mode, callbacks are set. For sync mode, we have to poll the dequeueBuffer APIs to queue and dequeue input output buffers respectively.
+
+6. **setupTime**: The time taken to set up the MediaExtractor/Muxer/Codec instance.
+
+    * MediaCodec: includes setting async/sync mode, configuring with a format and codec.start
+
+    * MediaExtractor: includes AMediaExtractor_new and setDataSource.
+
+    * MediaMuxer: includes creating the object, adding track, and starting the muxer.
+
+7. **destroyTime**: The time taken to stop and close MediaExtractor/Muxer/Codec instance.
+
+8. **minimumTime**: The minimum time taken to extract/mux/encode/decode a frame.
+
+9. **maximumTime**: The maximum time taken to extract/mux/encode/decode a frame.
+
+10. **averageTime**: Average time taken to extract/mux/encode/decode per frame.
+
+    * MediaCodec: computed as the total time taken to encode/decode all frames divided by the number of frames encoded/decoded.
+
+    * MediaExtractor: computed as the total time taken to extract all frames divided by the number of frames extracted.
+
+    * MediaMuxer: computed as the total time taken to mux all frames divided by the number of frames muxed.
+
+11. **timeToProcess1SecContent**: The time required to process one second worth input data.
+
+12. **totalBytesProcessedPerSec**: The number of bytes extracted/muxed/decoded/encoded per second.
+
+13. **timeToFirstFrame**: The time taken to receive the first output frame.
+
+14. **totalSizeInBytes**: The total output size of the operation (in bytes).
+
+15. **totalTime**: The time taken to perform the complete operation (i.e. Extract/Mux/Decode/Encode) for respective test vector.
+
+
+## Muxer
+1. **componentName**: The format of the output Media file. Following muxers are currently supported:
+     * Ogg, Webm, 3gpp, and mp4.
+
+## Decoder
+1. **componentName**: Includes all supported codecs on the device. Aliased components are skipped.
+    *   Video: H263, H264, H265, VPx, Mpeg4, Mpeg2, AV1
+    *   Audio: AAC, Flac, Opus, MP3, Vorbis, GSM, AMR-NB/WB
+
+## Encoder
+1. **componentName**: Includes all supported codecs on the device. Aliased components are skipped.
+    *   Video: H263, H264, H265, VPx, Mpeg4
+    *   Audio: AAC, Flac, Opus, AMR-NB/WB
+
+## Common Failures
+On some devices, if a codec isn't supported some tests may report a failure like "codec not found for"
+
+For example: On mobile devices without support for mpeg2 decoder, following failure is observed:
+```
+Unable to create codec by mime: video/mpeg2
+```
