The non-free answer can be found in a previous post (Gatut SE Ribowo
<gatutr@yahoo.com> 2000-09-28).
Quoting the pertinent part: "I tried to play VCD with MpegTV. It runs just
fine, but the FullScreen mode doesn't work." (S/He's obviously having some
problems.)
My own attempts to play VCD's with free tools has thus far been successful.
The problem I believe is in getting the data off the VCD. If the data (found
in the pseudo file </cdrom/mpegav/avseq0?.dat>) can be extracted correctly,
you can can watch the movie in the VCD. To test this little theory of mine I
copied </mpegav/avseq01.dat> using windoze. plaympeg played <avseq01.dat>
just fine. Under gtv the video looks a bit jumpier.
BTW, I tried both dd and cp under linux but the resulting file is unplayable
(or only the first frame, freeze-framed, appears). I also found out that the
program cdrdao can duplicate some VCD's.
Now, can anybody complete this half-baked answer? Does anybody know of any
linux way of extracting the data off a VCD so it can be piped to plaympeg,
etc? This probably will be the video equivalent of audio "ripping." VCD's are
the poor man's DVD and are more in keeping with the openness of the linux
movement.
