Method Detail

• configure

  void configure​(@Nullable
                 MediaFormat mediaFormat,
                 @Nullable
                 Surface surface,
                 @Nullable
                 MediaCrypto crypto,
                 int flags)

  Configures this adapter and the underlying MediaCodec. Needs to be called before start().

  See Also:

  MediaCodec.configure(MediaFormat, Surface, MediaCrypto, int)

• start

  void start()

  Starts this instance. Needs to be called after configure(android.media.MediaFormat, android.view.Surface, android.media.MediaCrypto, int).

  See Also:

  MediaCodec.start()

• dequeueInputBufferIndex

  int dequeueInputBufferIndex()

  Returns the next available input buffer index from the underlying MediaCodec or MediaCodec.INFO_TRY_AGAIN_LATER if no such buffer exists.

  Throws:

  IllegalStateException - If the underlying MediaCodec raised an error.

• dequeueOutputBufferIndex

  int dequeueOutputBufferIndex​(MediaCodec.BufferInfo bufferInfo)

  Returns the next available output buffer index from the underlying MediaCodec. If the next available output is a MediaFormat change, it will return MediaCodec.INFO_OUTPUT_FORMAT_CHANGED and you should call getOutputFormat() to get the format. If there is no available output, this method will return MediaCodec.INFO_TRY_AGAIN_LATER.

  Throws:

  IllegalStateException - If the underlying MediaCodec raised an error.

• getOutputFormat

  MediaFormat getOutputFormat()

  Gets the MediaFormat that was output from the MediaCodec.

  Call this method if a previous call to dequeueOutputBufferIndex(android.media.MediaCodec.BufferInfo) returned MediaCodec.INFO_OUTPUT_FORMAT_CHANGED.

• getInputBuffer

  @Nullable
  ByteBuffer getInputBuffer​(int index)

  Returns a writable ByteBuffer object for a dequeued input buffer index.

  See Also:

  MediaCodec.getInputBuffer(int)

• getOutputBuffer

  @Nullable
  ByteBuffer getOutputBuffer​(int index)

  Returns a read-only ByteBuffer for a dequeued output buffer index.

  See Also:

  MediaCodec.getOutputBuffer(int)

• queueInputBuffer

  void queueInputBuffer​(int index,
                        int offset,
                        int size,
                        long presentationTimeUs,
                        int flags)

  Submit an input buffer for decoding.

  The index must be an input buffer index that has been obtained from a previous call to dequeueInputBufferIndex().

  See Also:

  MediaCodec.queueInputBuffer(int, int, int, long, int)

• queueSecureInputBuffer

  void queueSecureInputBuffer​(int index,
                              int offset,
                              CryptoInfo info,
                              long presentationTimeUs,
                              int flags)

  Submit an input buffer that is potentially encrypted for decoding.

  The index must be an input buffer index that has been obtained from a previous call to dequeueInputBufferIndex().

  This method behaves like MediaCodec.queueSecureInputBuffer(int, int, android.media.MediaCodec.CryptoInfo, long, int), with the difference that info is of type CryptoInfo and not MediaCodec.CryptoInfo.

  See Also:

  MediaCodec.queueSecureInputBuffer(int, int, android.media.MediaCodec.CryptoInfo, long, int)

• releaseOutputBuffer

  void releaseOutputBuffer​(int index,
                           boolean render)

  Returns the buffer to the MediaCodec. If the MediaCodec was configured with an output surface, setting render to true will first send the buffer to the output surface. The surface will release the buffer back to the codec once it is no longer used/displayed.

  See Also:

  MediaCodec.releaseOutputBuffer(int, boolean)

• releaseOutputBuffer

  void releaseOutputBuffer​(int index,
                           long renderTimeStampNs)

  Updates the output buffer's surface timestamp and sends it to the MediaCodec to render it on the output surface. If the MediaCodec is not configured with an output surface, this call will simply return the buffer to the MediaCodec.

  See Also:

  MediaCodec.releaseOutputBuffer(int, long)

• flush

  void flush()

  Flushes the adapter and the underlying MediaCodec.

• release

  void release()

  Releases the adapter and the underlying MediaCodec.

• setOnFrameRenderedListener

  void setOnFrameRenderedListener​(MediaCodecAdapter.OnFrameRenderedListener listener,
                                  Handler handler)

  Registers a callback to be invoked when an output frame is rendered on the output surface.

  See Also:

  MediaCodec.setOnFrameRenderedListener(android.media.MediaCodec.OnFrameRenderedListener, android.os.Handler)

• setOutputSurface

  void setOutputSurface​(Surface surface)

  Dynamically sets the output surface of a MediaCodec.

  See Also:

  MediaCodec.setOutputSurface(Surface)

• setParameters

  void setParameters​(Bundle params)

  Communicate additional parameter changes to the MediaCodec instance.

  See Also:

  MediaCodec.setParameters(Bundle)

• setVideoScalingMode

  void setVideoScalingMode​(@VideoScalingMode
                           int scalingMode)

  Specifies the scaling mode to use, if a surface has been specified in a previous call to configure(android.media.MediaFormat, android.view.Surface, android.media.MediaCrypto, int).

  See Also:

  MediaCodec.setVideoScalingMode(int)
