Bug 18736

Created attachment 8027 [details]
dmesg output of segfaults in libmad and other libs

Confirming the current problem, even if I cannot confirm the problem started with the last libmad update: I haven't watched television on my laptop since many weeks.

[marja@cldrn_64 ~]$ rpm -qa | grep mad
lib64mad0-0.15.1b-20.mga6
[marja@cldrn_64 ~]$

Attaching dmesg output of 8 tries.

I'll attach the cli output of the last 3 tries later.

Cli output of 3 times starting VLC

Note that on these 3 tries, after some unpleasant noise instead of normal sound, the VLC screen disappeared, but the message about
"Segmentation fault      (core dumped)" only appeared after having done Ctrl+C.

Summary: some update broke DVB-T playback => mad update seems to have broken DVB-T playback / playing m3u streams
Source RPM: vlc-2.2.4-2.mga6, kaffeine-2.0.3-1.mga6 => mad-0.15.1b-20.mga6

Thanks for the update. This should be fixed in rel21 of libmad which I just submitted to Cauldron with a corrected patch that fixes layer1 and layer2 playback. Please test.

lib64mad0-0.15.1b-21.mga6.x86_64 does indeed fix it,  thanks Shlomi :-)

@ Christian

Please reopen if that release doesn't fix it for you.

Status: NEW => RESOLVED

It's fixed here, too. That was quick, thanks :-)

There is a new issue since the update: VLC and Kaffeine both crash when switching TV channel.

Maybe the same problem as reported in #18776. Shlomi, do you mind watching the suggested patch? Thanks.

I'll submit it as an update to stable.

latest libmad update fixed it.
