                              int maxDroppedFramesToNotify)

  Creates a new instance.

  Parameters:

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

  eventHandler - A handler to use when delivering events to eventListener. May be null if delivery of events is not required.

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

  maxDroppedFramesToNotify - The maximum number of frames that can be dropped between invocations of VideoRendererEventListener.onDroppedFrames(int, long).

                              int numOutputBuffers)

  Creates a new instance.

  Parameters:

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

  eventHandler - A handler to use when delivering events to eventListener. May be null if delivery of events is not required.

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

  maxDroppedFramesToNotify - The maximum number of frames that can be dropped between invocations of VideoRendererEventListener.onDroppedFrames(int, long).

  threads - Number of threads libgav1 will use to decode. If THREAD_COUNT_AUTODETECT is passed, then the number of threads to use is autodetected based on CPU capabilities.

  numInputBuffers - Number of input buffers.

  numOutputBuffers - Number of output buffers.

Method Detail

• getName

  public String getName()

  Description copied from interface: Renderer
  Returns the name of this renderer, for logging and debugging purposes. Should typically be the renderer's (un-obfuscated) class name.

  Returns:

  The name of this renderer.

• supportsFormat

  public final @com.google.android.exoplayer2.RendererCapabilities.Capabilities int supportsFormat​(Format format)

  Description copied from interface: RendererCapabilities
  Returns the extent to which the Renderer supports a given format.

  Parameters:

  format - The format.

  Returns:

  The RendererCapabilities.Capabilities for this format.

• createDecoder

  protected final Gav1Decoder createDecoder​(Format format,
                                            @Nullable
                                            CryptoConfig cryptoConfig)
                                     throws Gav1DecoderException

  Creates a decoder for the given format.

  Specified by:

  createDecoder in class DecoderVideoRenderer

  Parameters:

  format - The format for which a decoder is required.

  cryptoConfig - The CryptoConfig object required for decoding encrypted content. May be null and can be ignored if decoder does not handle encrypted content.

  Returns:

  The decoder.

  Throws:

  Gav1DecoderException

• renderOutputBufferToSurface

  protected void renderOutputBufferToSurface​(VideoDecoderOutputBuffer outputBuffer,
                                             Surface surface)
                                      throws Gav1DecoderException

  Description copied from class: DecoderVideoRenderer
  Renders the specified output buffer to the passed surface.

  The implementation of this method takes ownership of the output buffer and is responsible for calling VideoDecoderOutputBuffer.release() either immediately or in the future.

  Specified by:

  renderOutputBufferToSurface in class DecoderVideoRenderer

  Parameters:

  outputBuffer - VideoDecoderOutputBuffer to render.

  surface - Output Surface.

  Throws:

  Gav1DecoderException

• setDecoderOutputMode

  protected void setDecoderOutputMode​(@com.google.android.exoplayer2.C.VideoOutputMode int outputMode)

  Description copied from class: DecoderVideoRenderer
  Sets output mode of the decoder.

  Specified by:

  setDecoderOutputMode in class DecoderVideoRenderer

  Parameters:

  outputMode - Output mode.

• canReuseDecoder

  protected DecoderReuseEvaluation canReuseDecoder​(String decoderName,
                                                   Format oldFormat,
                                                   Format newFormat)

  Description copied from class: DecoderVideoRenderer
  Evaluates whether the existing decoder can be reused for a new Format.

  The default implementation does not allow decoder reuse.

  Overrides:

  canReuseDecoder in class DecoderVideoRenderer

  Parameters:

  decoderName - The name of the decoder.

  oldFormat - The previous format.

  newFormat - The new format.

  Returns:

  The result of the evaluation.
