       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.

       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.

       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.

       -ooutput-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 on).

       -fa|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

       -qnum 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).

       -bnum 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 needs.

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

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

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

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