NAME
yuv2lav - encodes lavtool's raw YUV frame streams into MJPEG files
SYNOPSIS
yuv2lav [-f a|A|q|m] [-q num] [-b num] [-I num] [-m num] [-v num] [-w file] -o output-file
DESCRIPTION
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.
OPTIONS
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
on).
-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
needs.
-m num This is the maximum size (in MB) per file. Normally this depends on the output file
type.
-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.

EXAMPLES
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.
