Segfault on Mpeg/MPG

Hello VLC community!

I have VLC 0.8.6a running on SuSE Linux 10.2. Whenever I try and open a MPG or MPEG format file, I get the following lovely output (ran with vlc -vvvv)

VLC works beautifully on everything else (avi, wmv, mk4, mkv, mov, etc). Do I have a bug here? I know my mpeg libraries are working because I can open the same file in movie player and it works fine. Any ideas?

Also, note that the

Code: Select all

** (.:29309): CRITICAL **: clearlooks_style_draw_focus: assertion `height >= -1' failed

Appears when I click file->quick open file.

It is probably useful to also note which versions of ffmpeg and mpec2dec I have on my machine:

Code: Select all

ffmpeg v. 0.4.9-8.pm.svn20070224 mpeg2dec v. 0.4.1-0.pm.2

How did you install VLC?

Using the RPMs from the VLC Project? wat does 'rpm -q vlc' give you?
I could see that you have ffmpeb and a52dec from the PackMan repository, and not from the VLC Repo. Can you try to change this and see if it helps?

[jduv]

Thanks for your reply.

Code: Select all

jduv@schala2-lnx fonts > rpm -q vlc vlc-0.8.6a-3.0

Also, I recently installed mplayer and it dies on mpg's as well. Totem, however, works perfectly fine. This leads me to believe that the problem may not be with VLC, but with ffmpeg or mpeg2dec. I installed VLC by following the directions on the VLC site for SuSE Linux 10.2

I changed over to version 0.0.6980-2.0 of ffmpeg and it still breaks =(.

[dimstar]

Can you verify that all the packages you use are the ones from the VLC Repo?

Maybe post a list of ,pm. RPMs. you can get with
rpm -qa | grep ".pm."
Maybe I see something else that's known to cause such behaviour.

And in plus, as a small test, be sure to delete the ~/.vlc directory, in case there is a broken cache.

Hey, thanks again for all your help!

The version of ffmpeg I have currently installed is the one from the packman repo, but I did switch it back to the vlc repo and try and run it. So I guess I should roll back all the packages associated with VLC to their VLC specific versions. I'll try that and repost.

[jduv]

Bingo.

Problem lies in libmpeg2. I rolled back to an earlier version (the one recommended by VLC) and it works beautifully.

Thanks for all your help guys. Now if I can just fix the other problem (see my ALSA broken pipe post).
