Public functions

experimentalEnableProcessedStreamChangedAtStart

fun experimentalEnableProcessedStreamChangedAtStart(): Unit

Enables the renderer to invoke onProcessedStreamChange on the first stream.

When not enabled, onProcessedStreamChange is invoked from the second stream onwards.

getDurationToProgressUs

fun getDurationToProgressUs(positionUs: Long, elapsedRealtimeUs: Long): Long

Returns minimum amount of playback clock time that must pass in order for the render call to make progress.

The default return time is DEFAULT_DURATION_TO_PROGRESS_US.

Parameters
`positionUs: Long`	The current render position in microseconds, measured at the start of the current iteration of the rendering loop.
`elapsedRealtimeUs: Long`	`elapsedRealtime` in microseconds, measured at the start of the current iteration of the rendering loop.

Returns
`Long`	Minimum amount of playback clock time that must pass before renderer is able to make progress.

handleMessage

fun handleMessage(@Renderer.MessageType messageType: Int, message: Any?): Unit

Handles a message delivered to the target.

Parameters
`@Renderer.MessageType messageType: Int`	The message type.
`message: Any?`	The message payload.

Throws
`androidx.media3.exoplayer.ExoPlaybackException`	If an error occurred whilst handling the message. Should only be thrown by targets that handle messages on the playback thread.

isEnded

fun isEnded(): Boolean

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

fun isReady(): Boolean

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.

render

fun render(positionUs: Long, elapsedRealtimeUs: Long): Unit

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.

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

Parameters
`positionUs: Long`	The current media time in microseconds, measured at the start of the current iteration of the rendering loop.
`elapsedRealtimeUs: Long`	`elapsedRealtime` in microseconds, measured at the start of the current iteration of the rendering loop.

Throws

Indicates the playback speed to this renderer.

The default implementation is a no-op.

Parameters

`targetPlaybackSpeed: Float`	The target factor by which playback should be sped up. This may be different from `currentPlaybackSpeed`, for example, if the speed is temporarily adjusted for live playback.

Throws
`androidx.media3.exoplayer.ExoPlaybackException`	If an error occurs handling the playback speed.

setRenderTimeLimitMs

fun setRenderTimeLimitMs(renderTimeLimitMs: Long): Unit

Sets a limit on the time a single render call can spend draining and filling the decoder.

This method should be called right after creating an instance of this class.

protected abstract fun processOutputBuffer(

    bufferFlags: Int,
    sampleCount: Int,
    bufferPresentationTimeUs: Long,
    isDecodeOnlyBuffer: Boolean,
    isLastBuffer: Boolean,
    format: Format!
): Boolean

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
`positionUs: Long`	The current media time in microseconds, measured at the start of the current iteration of the rendering loop.
`elapsedRealtimeUs: Long`	`elapsedRealtime` in microseconds, measured at the start of the current iteration of the rendering loop.
`codec: MediaCodecAdapter?`	The `MediaCodecAdapter` instance, or null in bypass mode were no codec is used.
`buffer: ByteBuffer?`	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`.
`bufferIndex: Int`	The index of the output buffer.
`bufferFlags: Int`	The flags attached to the output buffer.
`sampleCount: Int`	The number of samples extracted from the sample queue in the buffer. This allows handling multiple samples as a batch for efficiency.
`bufferPresentationTimeUs: Long`	The presentation time of the output buffer in microseconds.
`isDecodeOnlyBuffer: Boolean`	Whether the buffer timestamp is less than the intended playback start position.
`isLastBuffer: Boolean`	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.

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

Parameters

shouldUseBypass

protected fun shouldUseBypass(format: Format!): Boolean

Subclasses should only call this method if operating in a mode where buffers are not dequeued from the decoder, for example when using video tunneling).

Throws
`androidx.media3.exoplayer.ExoPlaybackException`	Thrown if an error occurs as a result of the output format change.
