DecoderVideoRenderer

protected DecoderVideoRenderer(
    allowedJoiningTimeMs: Long,
    eventHandler: Handler?,
    eventListener: VideoRendererEventListener?,
    maxDroppedFramesToNotify: Int
)
Parameters
allowedJoiningTimeMs: Long

The maximum duration in milliseconds for which this video renderer can attempt to seamlessly join an ongoing playback.

eventHandler: Handler?

eventListener: VideoRendererEventListener?

A listener of events. May be null if delivery of events is not required.

maxDroppedFramesToNotify: Int

Public functions

enableMayRenderStartOfStream

fun enableMayRenderStartOfStream(): Unit

Enables this renderer to render the start of the stream even if the state is not STATE_STARTED yet.

This is used to update the value of mayRenderStartOfStream passed to enable.

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.
