Comment (by Pierre-Anthony Lemieux):
The PTS/DTS calculations in the imf demuxer might be incorrect: it looks
like the PTS/DTS of the output frames should be equal to the PTS/DTS of
the input frames minus the entry point into the input MXF file plus the
offset of the input MXF file into the overall timeline -- like in
concatdec.c?
