Can somebody (anybody?) point me at a document that describes the
VIDDEC abstract decoder in terms of its design and implementation?
Specifically, I would like to learn hw the 'displayBufs' field in the
IVIDDEC_OutArgs is interpreted, used, and initialized (probably in the
other order :-)
The description given in "ividdec.h" and repeated in the HTML
documentation isn't terribly enlightening, IMHO:
"The decoder fills this structure to denote the buffer pointers for
current disaplable frames. In case of sequences having I & P frames
only, these values are identical to outBufs passed in process()."
Looking at the viddec_copy example code, I see
outArgs->displayBufs.numBufs = 0; /* important: indicate no displayBufs */
I am sure that both of these (the documentation given in "ividdec.h"
and the comment given in the code make sense in the context of some
larger work, I just don't know where to find that larger work.
