Command-line method to split MPEG2 file

[bmeehan]

I'm trying to create a web interface to select an existing MPEG2 file (recorded using MythTV on a PVR-250), input a start time and a length and then processes that in the background, delivering the short clip as an available download.

right now, i've gotten to this far:

$commandline="mpeg2cut " . $infile . " " . $outfile . " " . $GOPindex . " " . $cutstart . "-" . $cutend

mpeg2cut is a script by Gavin Hurlbut and is included with nuvexport by Chris Petersen. It uses avidemux2 to cut out the segments. But I haven't gotten it to work yet.

Question #1. Is this the best way to accomplish this? I need to make the file download available as quickly as possible to the user.

Question #2. Is there a way to do it without the dumuxing and the lot? I tried it once with just split() but it was pretty lousy.


Thanks for your video-guru help.

There is a way to do this without demuxing but its not a command line, its gui. The program is for linux and its called gopdit. I can provide more info if you'd like. Linux is a great os once you get used to it.
