 Posted: Sun Sep 01, 2013 7:33 pm Post subject: libav* libraries cause segfaults or failed compiles |
 |
|
I'm having an issue where a lot of packages that references libavcodec fails to compile and a lot of packages that use libavutils segfault. This started happening after I replaced ffmpeg-1.2.2 with libav-9.8. I have since re-installed ffmpeg (v1.2.3) and tried deleting the libraries and doing a revdep-rebuild, rolling back a few versions, compiling libav/ffmpeg manually etc.
Under both libav and ffmpeg, compiles end in error with messages along the lines of | Code: | avcodec.c: In function 'ffmpeg_OpenCodec':
avcodec.c: error: 'CODEC_ID_x' undeclared (first use in this function) |
where 'x' is a codec (eg "VORBIS", "AAC")
After many (successful) recompiles, mpv spits out the same segfault error every time

I am particularly confused by | Code: | | /var/tmp/portage/media-video/ffmpeg-1.2.3/work/ffmpeg-1.2.3/libavcodec/avpacket.c: No such file or directory. |
Is this a problem with the ebuild? |
