Comment (by helmboy):
In terms of parsing the MXF demuxer should pass all the data after the DC
to the codec which would handle the CDP and override the timestamps when
the internal timecode is set. The codec would be selected by the DID and
SDID. The ancillary header always uses the same field of 1, line of 9,
wrapping of 1 and YUV coding of 4.
I would write the code myself, but lack enough MXF source files to test it
on.
