Deprecated.

Description copied from interface: Renderer

Incrementally renders the SampleStream.

If the renderer is in the Renderer.STATE_ENABLED state then each call to this method will do work toward being ready to render the SampleStream when the renderer is started. If the renderer is in the Renderer.STATE_STARTED state then calls to this method will render the SampleStream in sync with the specified media positions.

The renderer may also render the very start of the media at the current position (e.g. the first frame of a video stream) while still in the Renderer.STATE_ENABLED state, unless it's the initial start of the media after calling Renderer.enable(RendererConfiguration, Format[], SampleStream, long, boolean, boolean, long, long) with mayRenderStartOfStream set to false.

This method should return quickly, and should not block if the renderer is unable to make useful progress.

This method may be called when the renderer is in the following states: Renderer.STATE_ENABLED, Renderer.STATE_STARTED.

Description copied from interface: Renderer

Whether the renderer is ready for the ExoPlayer instance to transition to Player.STATE_ENDED. The player will make this transition as soon as true is returned by all of its renderers.

Deprecated.

Returns the MediaFormat.KEY_OPERATING_RATE value for a given playback speed, current Format and set of possible stream formats.

The default implementation returns CODEC_OPERATING_RATE_UNSET.

Parameters:targetPlaybackSpeed - The target factor by which playback should be sped up. This may be different from the current playback speed, for example, if the speed is temporarily adjusted for live playback.format - The Format for which the codec is being configured.streamFormats - The possible stream formats.Returns:The codec operating rate, or CODEC_OPERATING_RATE_UNSET if no codec operating rate should be set.

Deprecated.

Processes an output media buffer.

When a new ByteBuffer is passed to this method its position and limit delineate the data to be processed. The return value indicates whether the buffer was processed in full. If true is returned then the next call to this method will receive a new buffer to be processed. If false is returned then the same buffer will be passed to the next call. An implementation of this method is free to modify the buffer and can assume that the buffer will not be externally modified between successive calls. Hence an implementation can, for example, modify the buffer's position to keep track of how much of the data it has processed.

Note that the first call to this method following a call to onPositionReset(long, boolean) will always receive a new ByteBuffer to be processed.

Parameters:positionUs - The current media time in microseconds, measured at the start of the current iteration of the rendering loop.elapsedRealtimeUs - SystemClock.elapsedRealtime() in microseconds, measured at the start of the current iteration of the rendering loop.codec - The MediaCodecAdapter instance, or null in bypass mode were no codec is used.buffer - The output buffer to process, or null if the buffer data is not made available to the application layer (see MediaCodec.getOutputBuffer(int)). This buffer can only be null for video data. Note that the buffer data can still be rendered in this case by using the bufferIndex.bufferIndex - The index of the output buffer.bufferFlags - The flags attached to the output buffer.sampleCount - The number of samples extracted from the sample queue in the buffer. This allows handling multiple samples as a batch for efficiency.bufferPresentationTimeUs - The presentation time of the output buffer in microseconds.isDecodeOnlyBuffer - Whether the buffer was marked with C.BUFFER_FLAG_DECODE_ONLY by the source.isLastBuffer - Whether the buffer is known to contain the last sample of the current stream. This flag is set on a best effort basis, and any logic relying on it should degrade gracefully to handle cases where it's not set.format - The Format associated with the buffer.Returns:Whether the output buffer was fully processed (for example, rendered or skipped).Throws:ExoPlaybackException - If an error occurs processing the output buffer.
