• setStartTimeUs

  public final void setStartTimeUs​(long startTimeUs)

  Deprecated.
  Sets the start time for the queue. Samples with earlier timestamps will be discarded or have the C.BUFFER_FLAG_DECODE_ONLY flag set when read.

  public final void discardUpstreamFrom​(long timeUs)

  Deprecated.
  Discards samples from the write side of the queue.

  Parameters:

  The source id.

• getUpstreamFormat

  @Nullable
  public final Format getUpstreamFormat()

  Deprecated.
  Returns the upstream Format in which samples are being queued.

• getLargestQueuedTimestampUs

  public final long getLargestQueuedTimestampUs()

  Deprecated.
  Returns the largest sample timestamp that has been queued since the last reset().

  Samples that were discarded by calling discardUpstreamSamples(int) are not considered as having been queued. Samples that were dequeued from the front of the queue are considered as having been queued.

  Returns:

  The largest sample timestamp that has been queued, or Long.MIN_VALUE if no samples have been queued.

• getLargestReadTimestampUs

  public final long getLargestReadTimestampUs()

  Deprecated.
  Returns the largest sample timestamp that has been read since the last reset().

  Returns:

  The largest sample timestamp that has been read, or Long.MIN_VALUE if no samples have been read.

• isLastSampleQueued

  public final boolean isLastSampleQueued()

  Deprecated.
  Returns whether the last sample of the stream has knowingly been queued. A return value of false means that the last sample had not been queued or that it's unknown whether the last sample has been queued.

  Samples that were discarded by calling discardUpstreamSamples(int) are not considered as having been queued. Samples that were dequeued from the front of the queue are considered as having been queued.

• getFirstTimestampUs

  public final long getFirstTimestampUs()

  Deprecated.

• isReady

  @CallSuper
  public boolean isReady​(boolean loadingFinished)

  Deprecated.
  Returns whether there is data available for reading.

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

  Parameters:

  loadingFinished - Whether no more samples will be written to the sample queue. When true, this method returns true if the sample queue is empty, because an empty sample queue means the end of stream has been reached. When false, this method returns false if the sample queue is empty.

• read

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

  Deprecated.
  Attempts to read from the queue.

  Formats read from this method may be associated to a DrmSession through FormatHolder.drmSession.

  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.

  loadingFinished - True if an empty queue should be considered the end of the stream.

  Returns:

  The result, which can be C.RESULT_NOTHING_READ, C.RESULT_FORMAT_READ or C.RESULT_BUFFER_READ.

  Throws:

  DecoderInputBuffer.InsufficientCapacityException - If the buffer has insufficient capacity to hold the data of a sample being read. The buffer timestamp and flags are populated if this exception is thrown, but the read position is not advanced.

  public final boolean seekTo​(int sampleIndex)

  Deprecated.

                              boolean allowTimeBeyondBuffer)

  Deprecated.
  Attempts to seek the read position to the keyframe before or at the specified time.

  Parameters:

  Returns:

  Whether the seek was successful.

  Parameters:

  timeUs - The time to advance to.

  Returns:

  The number of samples that need to be skipped, which may be equal to 0.

• skip

  public final void skip​(int count)

  Deprecated.
  Advances the read position by the specified number of samples.

  Parameters:

  count - The number of samples to advance the read position by. Must be at least 0 and at most getWriteIndex() - getReadIndex().

• discardTo

  public final void discardTo​(long timeUs,
                              boolean toKeyframe,
                              boolean stopAtReadPosition)

  Deprecated.
  Discards up to but not including the sample immediately before or at the specified time.

  Parameters:

  timeUs - The time to discard up to.

  toKeyframe - If true then discards samples up to the keyframe before or at the specified time, rather than any sample before or at that time.
