        Deprecated.
        Description copied from class: MediaCodecRenderer
        Processes an output media buffer.

        When a new ByteBuffer is passed to this method its position and limit delineate the data to be processed. The return value indicates whether the buffer was processed in full. If true is returned then the next call to this method will receive a new buffer to be processed. If false is returned then the same buffer will be passed to the next call. An implementation of this method is free to modify the buffer and can assume that the buffer will not be externally modified between successive calls. Hence an implementation can, for example, modify the buffer's position to keep track of how much of the data it has processed.

        Note that the first call to this method following a call to MediaCodecRenderer.onPositionReset(long, boolean) will always receive a new ByteBuffer to be processed.

        Specified by:
        processOutputBuffer in class MediaCodecRenderer
        Parameters:
        positionUs - 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.
        codec - The MediaCodecAdapter instance, or null in bypass mode were no codec is used.
        buffer - The output buffer to process, or null if the buffer data is not made available to the application layer (see MediaCodec.getOutputBuffer(int)). This buffer can only be null for video data. Note that the buffer data can still be rendered in this case by using the bufferIndex.
        bufferIndex - The index of the output buffer.
        bufferFlags - The flags attached to the output buffer.
        sampleCount - The number of samples extracted from the sample queue in the buffer. This allows handling multiple samples as a batch for efficiency.
        bufferPresentationTimeUs - The presentation time of the output buffer in microseconds.
        isDecodeOnlyBuffer - Whether the buffer was marked with C.BUFFER_FLAG_DECODE_ONLY by the source.
        isLastBuffer - Whether the buffer is known to contain the last sample of the current stream. This flag is set on a best effort basis, and any logic relying on it should degrade gracefully to handle cases where it's not set.
        format - The Format associated with the buffer.
        Returns:
        Whether the output buffer was fully processed (for example, rendered or skipped).
        Throws:
        ExoPlaybackException - If an error occurs processing the output buffer.
