Tim,
is it possible to read dvd VOB files in gem?
If you're on win, it should be possible with avisynth. You'll need Avisynth (which is a frame server, http://www.avisynth.org)) and the appropriate mpeg2 decoding plugins (dgdecode, http://neuron2.net/dgmpgdec/dgmpgdec.html) I can't test it right now (not sitting on my real computer), but it should work along these lines:
- create a d2v file of your dvd by running
dgindex.exe. This produces an index file that contains mainly the frame order of your dvd.
- create an avisynth script that reads your vobs
using the index file. It should contain the following lines at least:
LoadPlugin("c:\path\to\dgdecode.dll") mpeg2source("c:\path\to\indexfile.d2v") converttorgb32()
you could add filters for deinterlacing or some other stuff here as well, just add them before the converttorgb32() line.
- Open this avs file with gem and see if it works. If
it doesn't, drop me a mail ...
You shouldn't try to reverse the video and avoid arbitrary jumps within, since avisynth is not exactly optimised to do that sort of things.
I have no clue on how this could be done with linux ... One would need a frameserver for this sort of thing. It might be possible to open a dvd with the vlc client and stream it locally, I remember vaguely that pdp is capable of opening network streams.
hope this helps, Thoralf.
