Ben Speirs:
|Does anybody have an example parameter file to use with mpeg_encode?
...
|Also I'm really not sure what a lot of the fields do. Is there any
|better documentation?
I had the same trouble when I was cooking config files for MPEG
movie-making inside of fxtv. There was more useful info in the mpeg_encode
source package. I don't recall which files, but at least some of them
are installed with the FreeBSD package:
> pkg_info -L mpeg_encode-1.5b
...
/usr/local/bin/mpeg_encode
/usr/local/share/doc/mpeg_encode/users-guide.ps
/usr/local/share/doc/mpeg_encode/template.param
In case it might help, I've attached the mpeg_encode config file-related
snippet from fxtv_cnvt.sh which is used for cooking MPEG video and system
streams. The first part + one of the next 3 parts + one of the last two
parts are all appended together and __var__iables substituted appropriately.
|How about information on mpeg2encode? Should I be using this program
|instead? There were no man pages with this package.
You mean mpeg2codec? No experience with it, but I'd be interested in what
folks have to say as well. It wasn't there back when I was working with
MPEG video stream generation.
