If the output makes use of standard Android UI components, then this should normally be the
looper associated with the application's main thread, which can be obtained using ContextWrapper.getMainLooper(). Null may be passed if the output should be called

RendererCapabilitiesRenderer supports a given format. The returned value is
the bitwise OR of three properties:
RendererCapabilities.FORMAT_HANDLED,

RendererCapabilities.FORMAT_UNSUPPORTED_SUBTYPE and RendererCapabilities.FORMAT_UNSUPPORTED_TYPE.RendererCapabilities.ADAPTIVE_SEAMLESS, RendererCapabilities.ADAPTIVE_NOT_SEAMLESS and

BaseRendererBaseRenderer.onEnabled(boolean) has been called, and also when the stream has been replaced whilst
the renderer is enabled or started.
The default implementation is a no-op.
onStreamChanged in class BaseRendererformats - The enabled formats.offsetUs - The offset that will be added to the timestamps of buffers read via
BaseRenderer.readSource(FormatHolder, DecoderInputBuffer, boolean) so that decoder input
buffers have monotonically increasing timestamps.ExoPlaybackException - If an error occurs.protected void onPositionReset(long positionUs,
boolean joining)
BaseRendererBaseRenderer.onStreamChanged(Format[], long) has been called, and also when a position
discontinuity is encountered.
After a position reset, the renderer's SampleStream is guaranteed to provide samples
starting from a key frame.
The default implementation is a no-op.

RendererSampleStream.
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. It may
also render the very start of the media, for example the first frame of a video stream. 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.
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.
render in interface RendererpositionUs - 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.ExoPlaybackException - If an error occurs.protected void onDisabled()
BaseRendererThe default implementation is a no-op.
onDisabled in class BaseRendererpublic boolean isEnded()
RendererExoPlayer instance to transition to
Player.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:
Renderer.STATE_ENABLED, Renderer.STATE_STARTED.
public boolean isReady()
Renderer
If the renderer is in the Renderer.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 Renderer.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:
Renderer.STATE_ENABLED, Renderer.STATE_STARTED.
