Member Function Documentation

Frame * YUVStreamIO::getFrame (   )  [virtual]
 

returns a frame if one complete frame is available, otherwise null is returned.

This function is typically blocking. Don't use a NULL return value to conclude STREAMEOF, always check with getState()!

Reimplemented from RawStreamIO.
