Renders media read from a SampleStream.

Internally, a renderer's lifecycle is managed by the owning ExoPlayer. The renderer is transitioned through various states as the overall playback state and enabled tracks change. The valid state transitions are shown below, annotated with the methods that are called during each transition.

Renderer state transitions

Format support

The player will select a renderer based on the RendererCapabilities returned from getCapabilities. If the capabilities indicate support for a Format, the renderer is expected to handle SampleStream instances containing samples of this Format.

Resource management

Renderers should acquire resources like codecs when entering STATE_ENABLED for the first time. As the renderer may transition quickly to and from STATE_DISABLED, it is recommended to hold onto resources even when entering STATE_DISABLED. The player will explicitly call reset if the renderer is no longer needed, at which point any acquired limited resources should be released.

Configuration changes

As renderers are created once in the lifetime of a player, they may need to be re-configured later based on user settings or other environmental changes. This is generally done by handling player messages in handleMessage. There are many predefined common reconfigurations in MessageType, but custom renderers can add their own handling as needed.

Reading and rendering samples

The renderer receives a SampleStream to read from when enabled. When seamlessly transitioning from one item to another, the renderer may get new instances via replaceStream. Note that replaceStream may be called as soon as the end-of-stream signal has been read from the current SampleStream to allow reading new samples as early as possible. At this point, the renderer may still be processing samples from the previous stream(s). Once the current stream has been marked as final, no further calls to replaceStream are allowed to happen without first disabling the renderer again.

The player will regularly call render to let the renderer make progress. Once the renderer has prepared its internal pipeline to handle continuous playback progress, it should report itself as isReady. The player will only transition the renderer to STATE_STARTED if it reports itself as ready. If the renderer is blocked from making progress, it should return false from isReady, which will result in a stop operation back to STATE_ENABLED.

As long as it is in STATE_STARTED, the renderer is expected to actively output the data it is processing in line with the current playback position passed to render. The only exception is the very first sample (for example the first video frame), that is allowed to be output in STATE_ENABLED if the mayRenderStartOfStream flag was set in enable or later set via enableMayRenderStartOfStream.

Once the renderer finished all processing it needs to do (that is, no further call to render is needed) and the current stream is final, it should report itself as isEnded.

Timestamps and offsets

The renderer deals with potentially multiple consecutive input streams and has to handle position updates and stream transitions. This means there are multiple types of timestamps and offsets relevant in the context of this class:

  • SampleStream timestamp: The timestamp associated with each sample read from a SampleStream. This corresponds to the time in the Timeline.Period this stream belongs to. The current playback context can be obtained by using the Timeline and the MediaPeriodId provided together with each .
  • Renderer timestamp: The timestamp of the overall playback. This is a continuously increasing value across all input sample streams and what it passed to render as the current positionUs.
  • Stream offset: The constant offset between the current SampleStream timestamps and the renderer timestamp. This value is provided when setting a new stream in enable or replaceStream.
  • Stream start position: The renderer timestamp at which the current first starts playing. This value is provided when setting a new stream in enable or replaceStream. Note that it may be different from the Stream offset as streams can start at non-zero SampleStream timestamps.
  • Reset position: The Renderer timestamp at which continuous playback last started. This is either the stream start position provided in enable, or the position set in any subsequent resetPosition call. Note that this value is not changed when playback transitions seamlessly to a new stream after calling replaceStream. After any position reset, the samples read next are those needed to start playback at the intended reset position. In some cases, the renderer will encounter output data before the intended reset position (for example video frames starting from the previous keyframe). In these cases, the renderer should drop data internally and only start producing output at the intended reset position.

Constants

DEFAULT_DURATION_TO_PROGRESS_US

getDurationToProgressUs

MSG_CUSTOM_BASE

const val MSG_CUSTOM_BASE = 10000: Int

MSG_SET_AUDIO_ATTRIBUTES

const val MSG_SET_AUDIO_ATTRIBUTES = 3: Int

A type of a message that can be passed to an audio renderer via createMessage. The message payload should be an instance that will configure the underlying audio track. If not set, the default audio attributes will be used. They are suitable for general media playback.

Setting the audio attributes during playback may introduce a short gap in audio output as the audio track is recreated. A new audio session id will also be generated.

If tunneling is enabled by the track selector, the specified audio attributes will be ignored, but they will take effect if audio is later played without tunneling.

If the device is running a build before platform API version 21, audio attributes cannot be set directly on the underlying audio track. In this case, the usage will be mapped onto an equivalent stream type using getStreamTypeForAudioUsage.

To get audio attributes that are equivalent to a legacy stream type, pass the stream type to getAudioUsageForStreamType and use the returned C.AudioUsage to build an audio attributes instance.
