Today I upgraded my Gentoo dxr3 VDR system to the actual stable tree (vdr 1.6.0_p2 dxr3 vdr-dxr3 0.2.8 ffmpeg 0.5_p20373). After depclean and revdep-rebuild, I restart vdr. The OSD flash up and everything on my TV is frozen, vdr chrash with a segfault. The prevourios 0.5-r1 version of ffmpeg works fine. After googeling I found a bug http://developer.berlios.de/bugs/?func=detailbug&bug_id=14990&group_id=5358 that describe the crashing behavior.
Every 0.5_pxxxx ffmpeg version seems unstable and crashes like:
Code:
vdr[27014]: segfault at 20 ip b67280d9 sp b14f80a0 error 4 in libavcodec.so.52.37.1[b6662000+593000]


When I mask the buggy ffmpeg with
Code:
>=media-video/ffmpeg-0.5_p20373
in the /etc/portage/package.mask, I got a conflict with media-libs/x264:
Code:

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:               

media-libs/x264:0

  ('ebuild', '/', 'media-libs/x264-0.0.20091021', 'merge') pulled in by
    >=media-libs/x264-0.0.20091021 required by ('installed', '/', 'media-video/mplayer-1.0_rc4_p20091026-r1', 'nomerge')
    (and 3 more)

  ('ebuild', '/', 'media-libs/x264-0.0.20081006', 'merge') pulled in by
    <media-libs/x264-0.0.20090923 required by ('ebuild', '/', 'media-video/ffmpeg-0.5-r1', 'merge')
    (and 3 more)


After putting -x264 to my useflags, everthing compile and works fine.
