+# 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

+# <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
+```
+
+# <a name="wavExtractorFuzzer"></a> Fuzzer for libwavextractor
+
+## Plugin Design Considerations
+The fuzzer plugin for WAV extractor uses the `ExtractorFuzzerBase` class and

+
+
+## Build

-
- 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
-
- Local Stores Modified:
-    None
-
- Global Stores 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
+```

+#### 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
+```

+## Media Testing ##
+---
+#### XML Parser
+The XMLParser Test Suite validates the XMLParser available in libstagefright.
+
+Run the following steps to build the test suite:
+```
+m XMLParserTest
+```
+
+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/XMLParserTest/XMLParserTest /data/local/tmp/
+```
+
+To test 32-bit binary push binaries from nativetest.
+```
+adb push ${OUT}/data/nativetest/XMLParserTest/XMLParserTest /data/local/tmp/
+```
+
+usage: XMLParserTest
+```
+adb shell /data/local/tmp/XMLParserTest
+```
+Alternatively, the test can also be run using atest command.
+
+```
+atest XMLParserTest
+```
