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.

• isSeekable

  public boolean isSeekable()

  Deprecated.
  Description copied from interface: SeekMap
  Returns whether seeking is supported.

  Specified by:

  isSeekable in interface SeekMap

  Returns:

  Whether seeking is supported.

• getDurationUs

  public long getDurationUs()

  Deprecated.
  Description copied from interface: SeekMap
  Returns the duration of the stream in microseconds.

  Specified by:

  getDurationUs in interface SeekMap

  Returns:

  The duration of the stream in microseconds, or C.TIME_UNSET if the duration is unknown.

• getSeekPoints

  public SeekMap.SeekPoints getSeekPoints​(long timeUs)

  Deprecated.
  Description copied from interface: SeekMap
  Obtains seek points for the specified seek time in microseconds. The returned SeekMap.SeekPoints will contain one or two distinct seek points.

  Two seek points [A, B] are returned in the case that seeking can only be performed to discrete points in time, there does not exist a seek point at exactly the requested time, and there exist seek points on both sides of it. In this case A and B are the closest seek points before and after the requested time. A single seek point is returned in all other cases.

  Specified by:

  getSeekPoints in interface SeekMap

  Parameters:

  timeUs - A seek time in microseconds.

  Returns:

  The corresponding seek points.

• getSeekPoints

  public SeekMap.SeekPoints getSeekPoints​(long timeUs,
                                          int trackId)

  Deprecated.
  Equivalent to SeekMap.getSeekPoints(long), except it adds the trackId parameter.

  Parameters:

  timeUs - A seek time in microseconds.

  trackId - The id of the track on which to seek for SeekMap.SeekPoints. May be C.INDEX_UNSET if the extractor is expected to define the strategy for generating SeekMap.SeekPoints.

  Returns:

  The corresponding seek points.
