[mythtv-users] avidemux2 command line? nuv -->> DVD

[Cory Papenfuss]

 	I do basically the same thing, but I have figured out how to coerce 
avidemux2 into doing some things via the command line.  I run the gui manually 
to cut out commercials and then save the edit list.  After that, running the 
appropriate command line flags (check with avidemux --help) I can get it to 
demux.

 	I actually capture at a non-DVD resolution (640x480) and then 2pass 
encode at 352x480.  I'd like to run it from the card directly, but I can get 
better quality per disk space with offline MPEG2 encoding can do a better job 
than the PVR250 at low resolutions.  I can actually get all that done via a 
script that calls avidemux manually.

 	Be careful with the mplex.  My .nuv's from the PVR250 have a 
video/audio offset (usually mplex -O 3003mpt).  There also appears to be a bug 
in mplex that does some integer overflow around 66ms specified offset.  I 
haven't ferreted that out yet.
