Description Jochen Buchholz 2010-05-26 06:11:17 UTC
I updated my VDR Gentoo System. ffmpeg updates from 0.5-r1 to 0.5_p20373. Vdr crash after restarting with:
klogd: vdr[1856]: segfault at 20 ip b66d9879 sp b1bff0a0 error 4 in libavcodec.so.52.37.1[b6611000+59d000]
I downgraded ffmpeg to 0.5-r1 and everything works fine. I tried all masked version's of ffmpeg - same result. Thank goodness I saved the old ebuild of ffmpeg 0.5-r1 because it's gone from portage now :-( 

emerge --info is to long for pasting in this bug, because I got a Message that I reached 16Kb message size. I will append it.

Reproducible: Always

Steps to Reproduce:
1. Update and sync system emerge -NDu world 
2. emerge --depclean ; revdep-rebuild -i
3. restart vdr

Actual Results:  
klogd: vdr[1856]: segfault at 20 ip b66d9879 sp b1bff0a0 error 4 in libavcodec.so.52.37.1[b6611000+59d000]

Expected Results:  
none of above

Current stable Gentoo ffmpeg version seems buggy:

emerge --info

emerge --info is 24kb long - I cant paste it, because there is a 16KB limit.

please describe exactly how to trigger the segfault and provide a meaningful backtrace: http://www.gentoo.org/proj/en/qa/backtraces.xml

My hollywood plus card and my old mainboard had an hardware chrash last month. I use now the xine plugin with vdr-fbfe, so I can view much more formats. I tryed to get an new dxr3 card to simulate the error, no chance. I think we can close this bug.
