lavtrans can be used to convert the recorded videos from one MJPEG
"container" format to another one. It can also be used to split
the streams, or do destructive edits.
Like all the other mjpegtools(1) lavtrans also accept a
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,
not the 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
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.
