lavtrans(1)
NAME
lavtrans - Convert MJPEG videos to other MJPEG video for
mats
SYNOPSIS
lavtrans -o outputfile -f a|q|i|w [-i num] lavfile1 [lav_ file2 ... lavfileN]
DESCRIPTION
lavtrans can be used to convert the recorded videos from
MJPEG one "container" format to another. It can also be
used to split the streams, or do destructive edits.
Like all the other mjpegtools(1) lavtrans can also accept
an 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, no its format. As such it is not possible to
use it combine streams of different format.
OPTIONS
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
m - output to movtar 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 - filename
Multiple filenames as input are acceped, also mixing
of edit list files and other in video files.
BUGS
There seem to be problems with the transoding of large
Quicktime movies. One other thing is, that interlaced
movies only one field is extracted. So you get pictures
with the full horizontal size and the half vertical size.
