# MediaParser

`public final class MediaParser`
`extends Object` ``

java.lang.Object
↳ | android.media.MediaParser

Parses media container formats and extracts contained media samples and metadata.

This class provides access to a battery of low-level media container parsers. Each instance of this class is associated to a specific media parser implementation which is suitable for extraction from a specific media container format. The media parser implementation assignment depends on the factory method (see `create(MediaParser.OutputConsumer, String...)` and `createByName(String, MediaParser.OutputConsumer)`) used to create the instance.

Users must implement the following to use this class.

- `InputReader`: Provides the media container's bytes to parse.
- `OutputConsumer`: Provides a sink for all extracted data and metadata.

The following code snippet includes a usage example:

     MyOutputConsumer myOutputConsumer = new MyOutputConsumer();
     MyInputReader myInputReader = new MyInputReader("www.example.com");
     MediaParser mediaParser = MediaParser.create(myOutputConsumer);

     while (mediaParser.advance(myInputReader)) {}

     mediaParser.release();
     mediaParser = null;

The following code snippet provides a rudimentary `OutputConsumer` sample implementation which extracts and publishes all video samples:

     class VideoOutputConsumer implements MediaParser.OutputConsumer {

         private byte[] sampleDataBuffer = new byte[4096];
         private byte[] discardedDataBuffer = new byte[4096];
         private int videoTrackIndex = -1;
         private int bytesWrittenCount = 0;

         @Override
         public void onSeekMapFound(int i, @NonNull MediaFormat mediaFormat) {
           // Do nothing.
         }

         @Override
         public void onTrackDataFound(int i, @NonNull TrackData trackData) {
           MediaFormat mediaFormat = trackData.mediaFormat;
           if (videoTrackIndex == -1 &&
               mediaFormat
                   .getString(MediaFormat.KEY_MIME, /* defaultValue= */ "")
                   .startsWith("video/")) {
             videoTrackIndex = i;
           }
         }

         @Override
         public void onSampleDataFound(int trackIndex, @NonNull InputReader inputReader)
             throws IOException {
           int numberOfBytesToRead = (int) inputReader.getLength();
           if (videoTrackIndex != trackIndex) {
             // Discard contents.
             inputReader.read(
                 discardedDataBuffer,
                 /* offset= */ 0,
                 Math.min(discardDataBuffer.length, numberOfBytesToRead));
           } else {
             ensureSpaceInBuffer(numberOfBytesToRead);
             int bytesRead = inputReader.read(
                 sampleDataBuffer, bytesWrittenCount, numberOfBytesToRead);
             bytesWrittenCount += bytesRead;
           }
         }

         @Override
         public void onSampleCompleted(
             int trackIndex,
             long timeMicros,
             int flags,
             int size,
             int offset,
             @Nullable CryptoInfo cryptoData) {
           if (videoTrackIndex != trackIndex) {
             return; // It's not the video track. Ignore.
           }
           byte[] sampleData = new byte[size];
           int sampleStartOffset = bytesWrittenCount - size - offset;
           System.arraycopy(
               sampleDataBuffer,
               sampleStartOffset,
               sampleData,
               /* destPos= */ 0,
               size);
           // Place trailing bytes at the start of the buffer.
           System.arraycopy(
               sampleDataBuffer,
               bytesWrittenCount - offset,
               sampleDataBuffer,
               /* destPos= */ 0,
               /* size= */ offset);
           bytesWrittenCount = bytesWrittenCount - offset;
           publishSample(sampleData, timeMicros, flags);
         }

        private void ensureSpaceInBuffer(int numberOfBytesToRead) {
          int requiredLength = bytesWrittenCount + numberOfBytesToRead;
          if (requiredLength > sampleDataBuffer.length) {
            sampleDataBuffer = Arrays.copyOf(sampleDataBuffer, requiredLength);
          }
        }

    public static List<String> getParserNames (MediaFormat mediaFormat)

Returns an immutable list with the names of the parsers that are suitable for container formats with the given `MediaFormat`.

A parser supports a `MediaFormat` if the mime type associated with `MediaFormat.KEY_MIME` corresponds to the supported container format.

Parameters
`mediaFormat` | `MediaFormat`: The `MediaFormat` to check support for. This value cannot be `null`.

Returns
`List<String>` | The parser names that support the given `mediaFormat`, or the list of all parsers available if no container specific format information is provided. This value cannot be `null`. Value is `PARSER_NAME_UNKNOWN`, `PARSER_NAME_MATROSKA`, `PARSER_NAME_FMP4`, `PARSER_NAME_MP4`, `PARSER_NAME_MP3`, `PARSER_NAME_ADTS`, `PARSER_NAME_AC3`, `PARSER_NAME_TS`, `PARSER_NAME_FLV`, `PARSER_NAME_OGG`, `PARSER_NAME_PS`, `PARSER_NAME_WAV`, `PARSER_NAME_AMR`, `PARSER_NAME_AC4`, or `PARSER_NAME_FLAC`

### release

    public void release ()

Releases any acquired resources.

After calling this method, this instance becomes unusable and no other methods should be invoked.

### seek

    public void seek (MediaParser.SeekPoint seekPoint)

Seeks within the media container being extracted.

`SeekPoints` can be obtained from the `SeekMap` passed to `MediaParser.OutputConsumer.onSeekMapFound(android.media.MediaParser.SeekMap)`.

Following a call to this method, the `InputReader` passed to the next invocation of `advance(MediaParser.SeekableInputReader)` must provide data starting from `SeekPoint#position` in the stream.

Parameters
`seekPoint` | `MediaParser.SeekPoint`: The `SeekPoint` to seek to. This value cannot be `null`.

### setLogSessionId

    public void setLogSessionId (LogSessionId logSessionId)

Parameters
`logSessionId` | `LogSessionId`: This value cannot be `null`.

### setParameter

    public MediaParser setParameter (String parameterName,
                    Object value)

Sets parser-specific parameters which allow customizing behavior.

Must be called before the first call to `advance(MediaParser.SeekableInputReader)`.

Parameters
`parameterName` | `String`: The name of the parameter to set. See `PARAMETER_*` constants for documentation on possible values. This value cannot be `null`. Value is `PARAMETER_ADTS_ENABLE_CBR_SEEKING`, `PARAMETER_AMR_ENABLE_CBR_SEEKING`, `PARAMETER_FLAC_DISABLE_ID3`, `PARAMETER_MP4_IGNORE_EDIT_LISTS`, `PARAMETER_MP4_IGNORE_TFDT_BOX`, `PARAMETER_MP4_TREAT_VIDEO_FRAMES_AS_KEYFRAMES`, `PARAMETER_MATROSKA_DISABLE_CUES_SEEKING`, `PARAMETER_MP3_DISABLE_ID3`, `PARAMETER_MP3_ENABLE_CBR_SEEKING`, `PARAMETER_MP3_ENABLE_INDEX_SEEKING`, `PARAMETER_TS_MODE`, `PARAMETER_TS_ALLOW_NON_IDR_AVC_KEYFRAMES`, `PARAMETER_TS_IGNORE_AAC_STREAM`, `PARAMETER_TS_IGNORE_AVC_STREAM`, `PARAMETER_TS_IGNORE_SPLICE_INFO_STREAM`, `PARAMETER_TS_DETECT_ACCESS_UNITS`, `PARAMETER_TS_ENABLE_HDMV_DTS_AUDIO_STREAMS`, android.media.MediaParser.PARAMETER_IN_BAND_CRYPTO_INFO, or android.media.MediaParser.PARAMETER_INCLUDE_SUPPLEMENTAL_DATA
`value` | `Object`: The value to set for the given `parameterName`. See `PARAMETER_*` constants for documentation on the expected types. This value cannot be `null`.

Returns
`MediaParser` | This instance, for convenience. This value cannot be `null`.

Throws
`IllegalStateException` | If called after calling `advance(MediaParser.SeekableInputReader)` on the same instance.

### supportsParameter

    public boolean supportsParameter (String parameterName)

Returns whether the given `parameterName` is supported by this parser.

Parameters
`parameterName` | `String`: The parameter name to check support for. One of the `PARAMETER_*` constants. This value cannot be `null`. Value is `PARAMETER_ADTS_ENABLE_CBR_SEEKING`, `PARAMETER_AMR_ENABLE_CBR_SEEKING`, `PARAMETER_FLAC_DISABLE_ID3`, `PARAMETER_MP4_IGNORE_EDIT_LISTS`, `PARAMETER_MP4_IGNORE_TFDT_BOX`, `PARAMETER_MP4_TREAT_VIDEO_FRAMES_AS_KEYFRAMES`, `PARAMETER_MATROSKA_DISABLE_CUES_SEEKING`, `PARAMETER_MP3_DISABLE_ID3`, `PARAMETER_MP3_ENABLE_CBR_SEEKING`, `PARAMETER_MP3_ENABLE_INDEX_SEEKING`, `PARAMETER_TS_MODE`, `PARAMETER_TS_ALLOW_NON_IDR_AVC_KEYFRAMES`, `PARAMETER_TS_IGNORE_AAC_STREAM`, `PARAMETER_TS_IGNORE_AVC_STREAM`, `PARAMETER_TS_IGNORE_SPLICE_INFO_STREAM`, `PARAMETER_TS_DETECT_ACCESS_UNITS`, `PARAMETER_TS_ENABLE_HDMV_DTS_AUDIO_STREAMS`, android.media.MediaParser.PARAMETER_IN_BAND_CRYPTO_INFO, or android.media.MediaParser.PARAMETER_INCLUDE_SUPPLEMENTAL_DATA

Returns
`boolean` | Whether the given `parameterName` is supported.
