Field Detail

• FACTORY

  public static final ExtractorsFactory FACTORY

  Deprecated.
  Factory for Mp3Extractor instances.

• FLAG_ENABLE_CONSTANT_BITRATE_SEEKING

  public static final int FLAG_ENABLE_CONSTANT_BITRATE_SEEKING

  Deprecated.
  Flag to force enable seeking using a constant bitrate assumption in cases where seeking would otherwise not be possible.

  This flag is ignored if FLAG_ENABLE_INDEX_SEEKING is set.

  Constant Field Values

• FLAG_ENABLE_CONSTANT_BITRATE_SEEKING_ALWAYS

  public static final int FLAG_ENABLE_CONSTANT_BITRATE_SEEKING_ALWAYS

  Deprecated.
  Like FLAG_ENABLE_CONSTANT_BITRATE_SEEKING, except that seeking is also enabled in cases where the content length (and hence the duration of the media) is unknown. Application code should ensure that requested seek positions are valid when using this flag, or be ready to handle playback failures reported through Player.Listener.onPlayerError(com.google.android.exoplayer2.PlaybackException) with PlaybackException.errorCode set to PlaybackException.ERROR_CODE_IO_READ_POSITION_OUT_OF_RANGE.

  If this flag is set, then the behavior enabled by FLAG_ENABLE_CONSTANT_BITRATE_SEEKING is implicitly enabled.

  This flag is ignored if FLAG_ENABLE_INDEX_SEEKING is set.

  Constant Field Values

• FLAG_ENABLE_INDEX_SEEKING

  public static final int FLAG_ENABLE_INDEX_SEEKING

  Deprecated.
  Flag to force index seeking, in which a time-to-byte mapping is built as the file is read.

  This seeker may require to scan a significant portion of the file to compute a seek point. Therefore, it should only be used if one of the following is true:

  • The file is small.
  • The bitrate is variable (or it's unknown whether it's variable) and the file does not provide precise enough seeking metadata.

  Constant Field Values

• FLAG_DISABLE_ID3_METADATA

  public static final int FLAG_DISABLE_ID3_METADATA

  Deprecated.
  Flag to disable parsing of ID3 metadata. Can be set to save memory if ID3 metadata is not required.

• Mp3Extractor

  public Mp3Extractor()

  Deprecated.

• Mp3Extractor

  public Mp3Extractor​(@com.google.android.exoplayer2.extractor.mp3.Mp3Extractor.Flags int flags)

  Deprecated.

  Parameters:

  flags - Flags that control the extractor's behavior.

• Mp3Extractor

  public Mp3Extractor​(@com.google.android.exoplayer2.extractor.mp3.Mp3Extractor.Flags int flags,
                      long forcedFirstSampleTimestampUs)

  Deprecated.

  Parameters:

  flags - Flags that control the extractor's behavior.

  forcedFirstSampleTimestampUs - A timestamp to force for the first sample, or C.TIME_UNSET if forcing is not required.

Method Detail

• sniff

  public boolean sniff​(ExtractorInput input)
                throws IOException

  Deprecated.
  Description copied from interface: Extractor
  Returns whether this extractor can extract samples from the ExtractorInput, which must provide data from the start of the stream.

  If true is returned, the input's reading position may have been modified. Otherwise, only its peek position may have been modified.

  Specified by:

  sniff in interface Extractor

  Parameters:

  input - The ExtractorInput from which data should be peeked/read.

  Returns:

  Whether this extractor can read the provided input.

  Throws:

  IOException - If an error occurred reading from the input.

• init

  public void init​(ExtractorOutput output)

  Deprecated.
  Description copied from interface: Extractor
  Initializes the extractor with an ExtractorOutput. Called at most once.

  Specified by:

  init in interface Extractor

  Parameters:

  output - An ExtractorOutput to receive extracted data.

• seek

  public void seek​(long position,
                   long timeUs)

  Deprecated.
  Description copied from interface: Extractor
  Notifies the extractor that a seek has occurred.

  Following a call to this method, the ExtractorInput passed to the next invocation of Extractor.read(ExtractorInput, PositionHolder) is required to provide data starting from position in the stream. Valid random access positions are the start of the stream and positions that can be obtained from any SeekMap passed to the ExtractorOutput.

  Specified by:

  seek in interface Extractor

  Parameters:

  position - The byte offset in the stream from which data will be provided.

  timeUs - The seek time in microseconds.

• release

  public void release()

  Deprecated.
  Description copied from interface: Extractor
  Releases all kept resources.

  Specified by:

  release in interface Extractor

• read

  public int read​(ExtractorInput input,
                  PositionHolder seekPosition)
           throws IOException

  Deprecated.
  Description copied from interface: Extractor
  Extracts data read from a provided ExtractorInput. Must not be called before Extractor.init(ExtractorOutput).

  A single call to this method will block until some progress has been made, but will not block for longer than this. Hence each call will consume only a small amount of input data.

  In the common case, Extractor.RESULT_CONTINUE is returned to indicate that the ExtractorInput passed to the next read is required to provide data continuing from the position in the stream reached by the returning call. If the extractor requires data to be provided from a different position, then that position is set in seekPosition and Extractor.RESULT_SEEK is returned. If the extractor reached the end of the data provided by the ExtractorInput, then Extractor.RESULT_END_OF_INPUT is returned.

  When this method throws an IOException, extraction may continue by providing an ExtractorInput with an unchanged read position to a subsequent call to this method.

  Specified by:

  read in interface Extractor

  Parameters:

  input - The ExtractorInput from which data should be read.

  seekPosition - If Extractor.RESULT_SEEK is returned, this holder is updated to hold the position of the required data.

  Returns:

  One of the RESULT_ values defined in this interface.

  Throws:

  IOException - If an error occurred reading from or parsing the input.

• disableSeeking

  public void disableSeeking()

  Deprecated.
  Disables the extractor from being able to seek through the media.

  Please note that this needs to be called before read(com.google.android.exoplayer2.extractor.ExtractorInput, com.google.android.exoplayer2.extractor.PositionHolder).
