Gav1Decoder

public Gav1Decoder​(int numInputBuffers,
                   int numOutputBuffers,
                   int initialInputBufferSize,
                   int threads)
            throws[Gav1DecoderException](Gav1DecoderException.html "class in com.google.android.exoplayer2.ext.av1")

Deprecated.

Creates a Gav1Decoder. Parameters:numInputBuffers - Number of input buffers.numOutputBuffers - Number of output buffers.initialInputBufferSize - The initial size of each input buffer, in bytes.threads - Number of threads libgav1 will use to decode. If Libgav1VideoRenderer.THREAD_COUNT_AUTODETECT is passed, then this class will auto detect the number of threads to be used.Throws:Gav1DecoderException - Thrown if an exception occurs when initializing the decoder.

getName

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

Deprecated.

Description copied from interface: Decoder

Returns the name of the decoder. Returns:The name of the decoder.

-

createInputBuffer

protected[DecoderInputBuffer](../../decoder/DecoderInputBuffer.html "class in com.google.android.exoplayer2.decoder")createInputBuffer()

Deprecated.

Description copied from class: SimpleDecoder

Creates a new input buffer. Specified by:createInputBuffer in class SimpleDecoder<DecoderInputBuffer,​VideoDecoderOutputBuffer,​Gav1DecoderException>

-

createOutputBuffer

protected[VideoDecoderOutputBuffer](../../decoder/VideoDecoderOutputBuffer.html "class in com.google.android.exoplayer2.decoder")createOutputBuffer()

Deprecated.

Description copied from class: SimpleDecoder

Creates a new output buffer. Specified by:createOutputBuffer in class SimpleDecoder<DecoderInputBuffer,​VideoDecoderOutputBuffer,​Gav1DecoderException>

decode

@Nullable
protected[Gav1DecoderException](Gav1DecoderException.html "class in com.google.android.exoplayer2.ext.av1")decode​([DecoderInputBuffer](../../decoder/DecoderInputBuffer.html "class in com.google.android.exoplayer2.decoder")inputBuffer,[VideoDecoderOutputBuffer](../../decoder/VideoDecoderOutputBuffer.html "class in com.google.android.exoplayer2.decoder")outputBuffer,
                                      boolean reset)

Deprecated.

Description copied from class: SimpleDecoder

Decodes the inputBuffer and stores any decoded output in outputBuffer. Specified by:decode in class SimpleDecoder<DecoderInputBuffer,​VideoDecoderOutputBuffer,​Gav1DecoderException>Parameters:inputBuffer - The buffer to decode.outputBuffer - The output buffer to store decoded data. The flag C.BUFFER_FLAG_DECODE_ONLY will be set if the same flag is set on inputBuffer, but may be set/unset as required. If the flag is set when the call returns then the output buffer will not be made available to dequeue. The output buffer may not have been populated in this case.reset - Whether the decoder must be reset before decoding.Returns:A decoder exception if an error occurred, or null if decoding was successful.
