  public EmptySampleStream()

Method Detail

• isReady

  public boolean isReady()

  Description copied from interface: SampleStream
  Returns whether data is available to be read.

  Note: If the stream has ended then a buffer with the end of stream flag can always be read from SampleStream.readData(com.google.android.exoplayer2.FormatHolder, com.google.android.exoplayer2.decoder.DecoderInputBuffer, @com.google.android.exoplayer2.source.SampleStream.ReadFlags int). Hence an ended stream is always ready.

  Specified by:

  isReady in interface SampleStream

  Returns:

  Whether data is available to be read.

• maybeThrowError

  public void maybeThrowError()

  Description copied from interface: SampleStream
  Throws an error that's preventing data from being read. Does nothing if no such error exists.

  Specified by:

  maybeThrowError in interface SampleStream

• readData

  public int readData​(FormatHolder formatHolder,
                      DecoderInputBuffer buffer,
                      @com.google.android.exoplayer2.source.SampleStream.ReadFlags int readFlags)

  Description copied from interface: SampleStream
  Attempts to read from the stream.

  If the stream has ended then C.BUFFER_FLAG_END_OF_STREAM flag is set on buffer and C.RESULT_BUFFER_READ is returned. Else if no data is available then C.RESULT_NOTHING_READ is returned. Else if the format of the media is changing or if formatRequired is set then formatHolder is populated and C.RESULT_FORMAT_READ is returned. Else buffer is populated and C.RESULT_BUFFER_READ is returned.

  Specified by:

  readData in interface SampleStream

  Parameters:

  formatHolder - A FormatHolder to populate in the case of reading a format.

  buffer - A DecoderInputBuffer to populate in the case of reading a sample or the end of the stream. If the end of the stream has been reached, the C.BUFFER_FLAG_END_OF_STREAM flag will be set on the buffer.

  readFlags - Flags controlling the behavior of this read operation.

  Returns:

  The result of the read operation.

• skipData

  public int skipData​(long positionUs)

  Description copied from interface: SampleStream
  Attempts to skip to the keyframe before the specified position, or to the end of the stream if positionUs is beyond it.

  Specified by:

  skipData in interface SampleStream

  Parameters:

  positionUs - The specified time.

  Returns:

  The number of samples that were skipped.
