       lav2yuv [options] lavfile1 [lavfile2 ... lavfileN]


       lav2yuv  converts  an  MJPEG video sequence described by a
       sequence of MJPEG video files and/or edit  lists  pointing
       to  such  files  into the simple uncompressed planar 4:2:0
       Y'CbCr format, as used by  mpeg2enc(1)  MPEG  encoder  and
       image  processing  filters  like yuvscaler(1) or yuv2dfil­
       ter(1) or yuvdenoise(1).

       Output is to stdout  so  that  by  piping  the  output  of
       lav2yuv into a suitable pipeline it is possible to process
       and then encode or play back video recorded in any of  the
       mjpegtools MJPEG container formats: AVI, quicktime or mov­
       tar or edit lists describing  editted  versions  of  video
       held in such files.

       Mixing  different  files  with  different video formats is
       currently not possible.

       The -S -T -D options are used for scene  detection,  which
       is used by linux video studio.


       lav2yuv accepts the following options:

       -m   Force mono-chrome

       -S list.el
            Output a scene list with scene detection

       -T num
            Set scene detection threshold to num (default: 4)

       -D num
            Width decimation to use for scene detection (default:

       -o num
            Frame offset skip num frames in the beginning if  num
            is negative, all but the last num frames are skipped

       -f num
            Only  num  frames are written to stdout. 0 means that
            all frames are processed.
