NAME

   lavtrans - Convert MJPEG videos to other MJPEG video formats

SYNOPSIS

   lavtrans  -o  outputfile  -f a|q|i|w  [-i  num]  lavfile1 [lavfile2 ...
   lavfileN]

DESCRIPTION

   lavtrans can be used to convert the  recorded  videos  from  one  MJPEG
   "container"  format   to  another one. It can also be used to split the
   streams, or do destructive edits.

   Like all the other mjpegtools(1) lavtrans also accept a edit list  file
   in  place of actual video files. This allows it to be used to construct
   a stand-alone copy of the  editted  video  sequence  described  in  the
   editlist.

   Note  that  lavtrans can only change the container type of MJPEG video,
   not the format.  As such it is not possible to use it  combine  streams
   of different format.

OPTIONS

   lavtrans accepts the following options:

   -f [a|q|m|i|w]
        Specifies the output format that should be saved.
          a - output to AVI file
          q - output to Qicktime file
          i - output single JPEG images,
          w - output WAV file (sound only!)

   -i num
        Convert a single frame to a JPEG file.

   -o outputfile
        Specifies the name of the output file If you want as output single
        JPEG images the output file string must be a valid format string

   filename
        Multiple filenames as input are acceped, also mixing of edit  list
        files and other in video files.

BUGS

   There  seem  to  be  problems  with  the  transoding of large Quicktime
   movies. One other thing is that with interlaced movies only  one  field
   is  extracted.   So  you get pictures with the full horizontal size and
   half vertical size.
