You can't just use DTS instead of PTS for streams with bframes when there
should be PTS in the output. Such file will not be compliant. It will play in
some players but will have problems in other (that use decoders that don't
output frames in presentation order and rely on PTS, such as Apple decoders)
The proper way in this case would be to mux DTS instead of PTS for VFW streams.
IIRC avidemux already sets DTS (although it seems to set PTS on keyframes as
well, which I'm not sure is right; and avimux always muxes PTS which definitely
It seems that right now avidemux | matroskamux and avidemux | avimux wouldn't
