Member Function Documentation

void Frame::decodeAudio (  uint8_t *    dest = 0 ) 
 

decode audoi data

Parameters:
dest:  if 0, then a new audio buffer is allocated and added to the Frame if non 0, then the audio is decoded into the given memory space

void Frame::decodeVideo (  uint8_t *    dest = 0 ) 
 

decode video data

Parameters:
dest:  if 0, then a new video buffer is allocated and added to the Frame if non 0, then the video is decoded into the given memory space

void Frame::makeWriteableVBuf (    ) 
 

make copy if f is locked

If o is locked, a new VideoBuffer containing a deep copy of o. If o does not have videobuffer, it will be created from the DVFrame.
