       yuv2lav - encodes lavtool's raw YUV frame streams into MJPEG files


       yuv2lav [-f a|A|q|m] [-q num] [-b num] [-I num] [-m num] [-v num] [-w file] -o output-file


       yuv2lav  is  a  simple  MJPEG  encoder  for  raw  YUV frame streams as they are emitted by
       lav2yuv(1) or lavpipe(1), for example. It reads its input from stdin  and  is  capable  of
       writing AVI and Quicktime.


       The  command line options allow to specify the output file name, JPEG encoding quality and
       the amount of memory that will be allocated for JPEG compressed data.

       -o output-file
              This (compulsorary) option sets the name of the file that yuv2lav  will  write  its
              output  to. If the output file contains a % (e.g. file%02d.avi), the output will be
              written to multiple files in case this is necessary (file00.avi, file01.avi and  so

       -f a|A|q
              This sets the output file format, which has to be one of
               a - for AVI file output,
               A - for AVI with reversed fields,
               q - for Quicktime output or
              AVI  with  reversed  field  of  course  only  makes  sense  if yuv2lav's feed is an
              interlaced video source and should only be needed if you experience frame  reversal
              problems  in your output.  If you don't use that option yuv2lav will set the output
              format to AVI if the last 3 char are avi, or to Quicktime if you use  mov.  If  you
              use the -f option it overides the setting in the filename

       -q num This  option  specifies the JPEG encoding quality as passed through to libjpeg. The
              default value is 80, num must  lie  within  24...100  inclusive  (think  of  it  as
              percentage  values,  although with a lossy compression algorithm like JPEG, keeping
              100% of the original quality is of course not really possible).

       -b num This option specifies the size of the buffer (in kBytes) that yuv2lav allocates  in
              order  to  store  the  compressed  JPEG  data  in  it.  The default value (256k) is
              perfectly enough for 100% quality full sized PAL/NTSC, but if you want to  compress
              Super-Mega-HDTV  or  if you are low on memory, you can use this option to suit your

       -m num This is the maximum size (in MB) per file. Normally this depends on the output file

       -I num Force a specific interlacing type. 0 means no interlacing, 1 means top-field-first,
              2 means bottom-field-first.

       -w file
              This is the WAV file containing audio data to be combined  with  the  video  stream
              into the output file.

       -v num Verbosity level. 0 means only print error messages, 2 prints full debug output.

       lav2yuv movie.avi | yuv2lav -fq -q 30 lowbitrate.qt
              would recompress movie.avi as a low bit rate Quicktime file.

       lavpipe input.pli | yuv2lav -q80 output.avi
              would save the movie assembled by lavpipe as a single AVI file.
