       lavtrans - Convert MJPEG videos to other MJPEG video formats

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

       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.

       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

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

       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.

       This man page was written by Bernhard Praschinger.
