Subject:    avi to mpeg ?

Hello,
 Are there any avi to mpeg conversion tools for Linux?  

  Also, xawtv and kwintv both capture to avi files, but the captured
files are huge: e.g. 150MB/min.  bttvgrab does not capture to avi, and
I have had trouble converting the captured pmm files to mpeg-1 if there
are more than 2000 to 3000 frames.  At 30 frames per second, that's
not big enough for many purposes.  Further the quality is not too
good.

If one wanted to capture video segments of 1/2 to 1 hour from TV or
VCR, can anyone make recommendations? 

TIA,
 -sen

You could try qtmpeg at http://www.ee.up.ac.za/~justin/v4l2.  It is still very 
crude, and v4l2 only, but it works.  Captures QT movies in YVU9, RAW, or 
RTjpeg formats.  xanim can view the YVU9 and RAW formats.  qtplay (included) 
can play the RTjpeg formats.  It also includes tools to convert (some) QT 
movies (at least those captured using this package) to mpeg.

tried mjpeg instead of raw rgb data (xawtv >= 3.0)?

How do you do it?   I couldn't find the options to capture in mjpeg
format.

TIA,

You are not very good in searching...

xawtv has it in one of the menus of the recording dialogbox.

streamer --help says:

[ ... ]
  -f format   specify output format       [none]
[ ... ]
formats:
  raw data:      rgb, gray, 422, 422p, 420p
  file formats:  ppm, pgm, jpeg
  movie formats: avi15, avi24, mjpeg
                               ^^^^^
[ ... ]

This needs libjpeg which is a compile time option.  Make sure
you have libjpeg-devel installed when compiling xawtv.
