Public bug reported: Binary package hint: ffmpeg
OS: Karmic 9.10 Arch: x86_64 Package: libavcodec-dev 4:0.5+svn20090706-2ubuntu2 Installing libavcodec-dev on Ubuntu Karmic (9.10), /usr/include/libavcodec/avcodec.h explicitely says: #define LIBAVCODEC_VERSION_MAJOR 52 #define LIBAVCODEC_VERSION_MINOR 20 #define LIBAVCODEC_VERSION_MICRO 0 which, according to upstream ffmpeg's repository, relates to this commit (from Thu, 26 Feb 2009): http://git.ffmpeg.org/?p=ffmpeg;a=commitdiff;h=68f29ac60ec3f3c33f142497337666a36288d54d Though, from .deb file: $ apt-cache show libavcodec-dev | grep Version: Version: 4:0.5+svn20090706-2ubuntu2 The supposed SVN version number definitely is not the actual one ! I'd recommend upgrade to at least libavcodec 52.30 ( see http://git.ffmpeg.org/?p=ffmpeg;a=commitdiff;h=ff4d4521ceefa3bfb3d7f38ecf67d9a70c69b5a5 from Sun, 31 May 2009) which introduces a new feature called lock manager. Without this, ffmpeg is not thread/instance safe, meaning that 2 applications using ffmpeg's decoders at the same time (unless they are statically compiled) have good chances to crash. (might need to be forwarded to Debian Multimedia people as well ...) ** Affects: ffmpeg (Ubuntu) Importance: Undecided Status: New -- Bad avcodec public version number in karmic and missing lock manager feature causing concurrent lib access issues https://bugs.launchpad.net/bugs/483317 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
