Method Detail

init

void init(PixelStore pixelStore)
   throws IOException

Starts reading media data from the source.

Parameters:

pixelStore - The pixel store where the buffers for the returned pictures will be borrowed from.

Throws:

IOException

seekFrames

void seekFrames(int seekFrames)
         throws IOException

Skips some number of frames in this source

Parameters:

skipFrames - The number of frames to skip

Throws:

IOException

getNextVideoFrame

VideoFrameWithPacket getNextVideoFrame()
                                throws IOException

Gets the next video frame from this source

Returns:

A picture holding the decoded frame, when the picture is not used it must be returned to the appropriate pixel store for the maximum efficiency.

Throws:

IOException

getNextAudioFrame

AudioFrameWithPacket getNextAudioFrame()
                                throws IOException

Gets the next decoded audio frame from this source

Returns:

The audio buffer containing PCM samples of the decoded audio and the audio format.

Throws:

IOException

finish

void finish()

Closes the input and flushes all the buffers related to this source.
