Decodes and renders video using MediaCodec.

This renderer accepts the following messages sent via createMessage on the playback thread:

Message with type MSG_SET_VIDEO_OUTPUT to set the output. The message payload should be the target Surface, or null to clear the output. Other non-null payloads have the effect of clearing the output.
Message with type MSG_SET_VIDEO_OUTPUT_RESOLUTION to set the output resolution. The message payload should be the output resolution in Size.
Message with type MSG_SET_SCALING_MODE to set the video scaling mode. The message payload should be one of the integer scaling modes in C.VideoScalingMode. Note that the scaling mode only applies if the Surface targeted by this renderer is owned by a android.view.SurfaceView.
Message with type MSG_SET_CHANGE_FRAME_RATE_STRATEGY to set the strategy used to call setFrameRate.
Message with type MSG_SET_VIDEO_FRAME_METADATA_LISTENER to set a listener for metadata associated with frames being rendered. The message payload should be the , or null.

    @Nullable Object message
)

Handles a message delivered to the target.

Parameters
`@Renderer.MessageType int messageType`	The message type.

isEnded

public boolean isEnded()

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

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

Returns
`boolean`	Whether the renderer is ready for the player to transition to the ended state.

isReady

public boolean isReady()

Whether the renderer is able to immediately render media from the current position.

If the renderer is in the STATE_STARTED state then returning true indicates that the renderer has everything that it needs to continue playback. Returning false indicates that the player should pause until the renderer is ready.

If the renderer is in the STATE_ENABLED state then returning true indicates that the renderer is ready for playback to be started. Returning false indicates that it is not.

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

Returns
`boolean`	Whether the renderer is ready to render media.

public void render(long positionUs, long elapsedRealtimeUs)

Incrementally renders the SampleStream.

If the renderer is in the 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 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 STATE_ENABLED state, unless it's the initial start of the media after calling enable with mayRenderStartOfStream set to false.

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

)

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 will always receive a new ByteBuffer to be processed.

Parameters
`long positionUs`	The current media time in microseconds, measured at the start of the current iteration of the rendering loop.
`long elapsedRealtimeUs`	`elapsedRealtime` in microseconds, measured at the start of the current iteration of the rendering loop.
`@Nullable MediaCodecAdapter codec`	The `MediaCodecAdapter` instance, or null in bypass mode were no codec is used.
`@Nullable ByteBuffer buffer`	The output buffer to process, or null if the buffer data is not made available to the application layer (see `getOutputBuffer`). 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`.
`int bufferIndex`	The index of the output buffer.
`int bufferFlags`	The flags attached to the output buffer.
`int sampleCount`	The number of samples extracted from the sample queue in the buffer. This allows handling multiple samples as a batch for efficiency.
`long bufferPresentationTimeUs`	The presentation time of the output buffer in microseconds.
`boolean isDecodeOnlyBuffer`	Whether the buffer timestamp is less than the intended playback start position.
`boolean 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 format`	The `Format` associated with the buffer.

Returns
`boolean`	Whether the output buffer was fully processed (for example, rendered or skipped).

Throws
`androidx.media3.exoplayer.ExoPlaybackException`	If an error occurs processing the output buffer.

`long presentationTimeUs`	The presentation time of the output buffer, in microseconds.
`long releaseTimeNs`	The wallclock time at which the frame should be displayed, in nanoseconds.

resetCodecStateForFlush

@CallSuper
protected void resetCodecStateForFlush()

Resets the renderer internal state after a codec flush.

setOutputSurfaceV23

@RequiresApi(value = 23)
protected void setOutputSurfaceV23(MediaCodecAdapter codec, Surface surface)

shouldDropBuffersToKeyframe

protected boolean shouldDropBuffersToKeyframe(
    long earlyUs,
    long elapsedRealtimeUs,
    boolean isLastBuffer
)

Returns whether to drop all buffers from the buffer being processed to the keyframe at or after the current playback position, if possible.

Parameters
`long earlyUs`	The time until the current buffer should be presented in microseconds. A negative value indicates that the buffer is late.
`long elapsedRealtimeUs`	`elapsedRealtime` in microseconds, measured at the start of the current iteration of the rendering loop.
`boolean isLastBuffer`	Whether the buffer is the last buffer in the current stream.

shouldDropOutputBuffer

protected boolean shouldDropOutputBuffer(
    long earlyUs,
    long elapsedRealtimeUs,
    boolean isLastBuffer
)

Returns whether the buffer being processed should be dropped.

Parameters
`long earlyUs`	The time until the buffer should be presented in microseconds. A negative value indicates that the buffer is late.
`long elapsedRealtimeUs`	`elapsedRealtime` in microseconds, measured at the start of the current iteration of the rendering loop.
`boolean isLastBuffer`	Whether the buffer is the last buffer in the current stream.

shouldForceRenderOutputBuffer

protected boolean shouldForceRenderOutputBuffer(
    long earlyUs,
    long elapsedSinceLastRenderUs
)

Returns whether to force rendering an output buffer.

Parameters
`long earlyUs`	The time until the current buffer should be presented in microseconds. A negative value indicates that the buffer is late.
`long elapsedSinceLastRenderUs`	The elapsed time since the last output buffer was rendered, in microseconds.

Returns
`boolean`	Returns whether to force rendering an output buffer.

shouldInitCodec

protected boolean shouldInitCodec(MediaCodecInfo codecInfo)

shouldSkipBuffersWithIdenticalReleaseTime

protected boolean shouldSkipBuffersWithIdenticalReleaseTime()

Returns whether to skip buffers that have an identical release time as the previous released buffer.

shouldSkipDecoderInputBuffer

protected boolean shouldSkipDecoderInputBuffer(DecoderInputBuffer buffer)

Returns whether the input buffer should be skipped before the decoder.

This can be used to skip decoding of buffers that are not depended on during seeking. See BUFFER_FLAG_NOT_DEPENDED_ON.

Parameters
`DecoderInputBuffer buffer`	The input buffer.

shouldUseDetachedSurface

protected boolean shouldUseDetachedSurface(MediaCodecInfo codecInfo)

skipOutputBuffer

protected void skipOutputBuffer(
    MediaCodecAdapter codec,
    int index,
    long presentationTimeUs
)

Skips the output buffer with the specified index.

Parameters
`MediaCodecAdapter codec`	The codec that owns the output buffer.
`int index`	The index of the output buffer to skip.
`long presentationTimeUs`	The presentation time of the output buffer, in microseconds.

supportsFormat

@RendererCapabilities.Capabilities
protected int supportsFormat(MediaCodecSelector mediaCodecSelector, Format format)

Returns the Capabilities for the given Format.

Parameters
`MediaCodecSelector mediaCodecSelector`	The decoder selector.
`Format format`	The `Format`.

Returns
`int`	The `Capabilities` for this `Format`.

Throws
`androidx.media3.exoplayer.mediacodec.MediaCodecUtil.DecoderQueryException`	If there was an error querying decoders.

updateDroppedBufferCounters

protected void updateDroppedBufferCounters(
    int droppedInputBufferCount,
    int droppedDecoderBufferCount
)

Updates local counters and decoderCounters to reflect that buffers were dropped.

Parameters
`int droppedInputBufferCount`	The number of buffers dropped from the source before being passed to the decoder.
`int droppedDecoderBufferCount`	The number of buffers dropped after being passed to the decoder.

updateVideoFrameProcessingOffsetCounters

protected void updateVideoFrameProcessingOffsetCounters(long processingOffsetUs)

Updates local counters and DecoderCounters with a new video frame processing offset.

Parameters
`long processingOffsetUs`	The video frame processing offset.
