Field Detail

• RESULT_CONTINUE

  static final int RESULT_CONTINUE

  Deprecated.
  Returned by read(ExtractorInput, PositionHolder) if the ExtractorInput passed to the next read(ExtractorInput, PositionHolder) is required to provide data continuing from the position in the stream reached by the returning call.

• RESULT_SEEK

  static final int RESULT_SEEK

  Deprecated.
  Returned by read(ExtractorInput, PositionHolder) if the ExtractorInput passed to the next read(ExtractorInput, PositionHolder) is required to provide data starting from a specified position in the stream.

• RESULT_END_OF_INPUT

  static final int RESULT_END_OF_INPUT

  Deprecated.
  Returned by read(ExtractorInput, PositionHolder) if the end of the ExtractorInput was reached. Equal to C.RESULT_END_OF_INPUT.

Method Detail

• sniff

  boolean sniff​(ExtractorInput input)
         throws IOException

  Deprecated.
  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.

  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

  void init​(ExtractorOutput output)

  Deprecated.
  Initializes the extractor with an ExtractorOutput. Called at most once.

  Parameters:

  output - An ExtractorOutput to receive extracted data.

• read

  @com.google.android.exoplayer2.extractor.Extractor.ReadResult int read​(ExtractorInput input,
                                                                         PositionHolder seekPosition)
                                                                  throws IOException

  Deprecated.
  Extracts data read from a provided ExtractorInput. Must not be called before 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, 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 RESULT_SEEK is returned. If the extractor reached the end of the data provided by the ExtractorInput, then 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.

  Parameters:

  input - The ExtractorInput from which data should be read.

  seekPosition - If 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.

• seek

  void seek​(long position,
            long timeUs)

  Deprecated.
  Notifies the extractor that a seek has occurred.

  Following a call to this method, the ExtractorInput passed to the next invocation of 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.

  Parameters:

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

  timeUs - The seek time in microseconds.

• release

  void release()

  Deprecated.
  Releases all kept resources.
