[PlanetCCRMA] mpeg3toc segfault

Hi Pat,
   Thanks for answering. Here's the documentation we found on the
Cinelerra site:


Down a bit under 'supported file formats' we found:

# AVI with mp3 audio and MPEG-4 video
# MPEG 1, 2 video

You need to run mpeg3toc to generate a table of contents for these,
then load the table of contents. Mpeg3toc needs the absolute path of
the MPEG file. If you want to edit a DVD, find the corresponding ifo
file for the program of interest and run

          mpeg3toc /cdrom/video_ts/vts_01_0.ifo dvd.toc

or something similar. Then load dvd.toc. This allows frame accurate
editing where none would be possible otherwise.

This segfaulted on my son's machine so I loaded Cinelerra on my
machine this morning and here it didn't segfault and does produce an
output file:

[mark@Godzilla mark]$ mpeg3toc /home/mark/fw-tut1.avi test.toc
[mark@Godzilla mark]$ amples=131072

(Yes - 'amples' not 'samples' - don't ask me...)

But then loading this into Cinelerra doesn't work. I start Cinelerra
and then try to load the toc but Cinelerra just quits:

rk@Godzilla mark]$ cinelerra

I presume it must be possible to load avi files into Cinelerra for
viewing? I don't know as I've never used this app before.

My son is trying to learn about making videos of his XBox adventures
and we want to put them together on one of our Linux machines.
