[olug] Video production

[Jon Larsen]

Eric,

Check out MPlayer.  I have found it to be the best video player for 
linux.  It's command line, and has a wide variety of options, including 
output to a file.  The latest version will play VCD and DVD from the 
command line.  Pretty slick.  You may be able to use it to convert to your 
final output format.  Visit the home page for all the info.

Here's the info from Freshmeat:
  MPlayer is a movie and animation player based on the 0.90pre5 version of 
MPEGplayer and the Avifile library. It uses mpeg2dec/libmpeg2 for MPEG 
decoding. The supported file formats are: MPEG 1/2 (MPG, DAT, BIN, VOB) and 
AVI (Mpeg/PCM/AC3/DivX/MS-ADPCM/aLaw audio and MPEG4/DivX/Indeo/CVID video 
codecs). It supports hardware YUV colorspace conversion and scaling via 
mga_vid/syncfb devices or the X11 Xv extension.
