Deprecated.

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](https://developer.android.com/reference/java/lang/String.html "class or interface in java.lang")getName()

Deprecated.

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.html "class in com.google.android.exoplayer2")format)

Deprecated.

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

Deprecated.

Creates a decoder for the given format. Specified by:createDecoder in class DecoderVideoRendererParameters: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](../../decoder/VideoDecoderOutputBuffer.html "class in com.google.android.exoplayer2.decoder")outputBuffer,[Surface](https://developer.android.com/reference/android/view/Surface.html "class or interface in android.view")surface)

Deprecated.

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 DecoderVideoRendererParameters:outputBuffer - VideoDecoderOutputBuffer to render.surface - Output Surface.Throws:Gav1DecoderException

setDecoderOutputMode

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

Deprecated.

Deprecated.

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 DecoderVideoRendererParameters:decoderName - The name of the decoder.oldFormat - The previous format.newFormat - The new format.Returns:The result of the evaluation.
