vlc 1.1.8 crash segfault on DVB-T

[djsb]

Hi all,

I'm using vlc with an avermedia card on Linux (ubuntu 10.04) / Windows (xp) and i have the same crash behavior.
In our country (portugal) DVB-T Stream is mpeg4 based. VLC starts showing 2 or 3 seconds of video and audio, but then segfaults.

I've tested version 1.0.4 and 1.0.6 as well as the last 1.1.8 on Windows and Linux. The capture card works great with mplayer or their own software (Avermedia USB Video capture HD 830).

Here's the output:

My best guess is that reception errors occur and the codec is not handling that very well. It's really impossible to find the problem with so few details anyway.

[djsb]

What further details can i supply to you?

On windows my signal strength is announced by the hardware/software vendor as between 80 a 95%.
This happens only with vlc (linux or windows xp), not mplayer or avermedia own software.

[Rémi Denis-Courmont]

valgrind trace might be helpful in finding the culprit. Fixing the bug may be more difficult as it depends on the right expert looking at the issue.

[djsb]

As you suggested i include a valgrind debug.

thank you

[Rémi Denis-Courmont]

This looks like a bug in libdvbpsi. It probably does not deal with corrupt TS packets correctly.

You should report it to dvbpsi developers...

[djsb]

It looks this libdvbpsi is maintained by vlc developers. Isn't this the forum?

best regards and thank you for your help.

[Rémi Denis-Courmont]

It's the same cover organization. But I don't think dvbpsi developers read this forum.
