A couple of comments: - yes, h264 is a very complicated set of techniques and therefore almost all bugreports regarding h264 decoding bugs without a proper and concrete sample is of very little use. The maintainers really need to be able to reproduce exactly the situation that you are experiences.
- Ubuntu does not follow http://ffmpeg.org, but http://libav.org. Use http://bugzilla.libav.org as upstream bug tracker. As you have experienced, the ffmpeg developers are not exactly helpful when it comes to bugreports regarding their upstream libav.org. Please refrain from advocating to replace libav by ffmpeg; this has been discussed before and is dismissed. - There are a number of h264 improvments scheduled for the next point release 0.8.1 (and also possibly for 0.7.5). - libavcodec.so (both in ffmpeg and libav) do not support "native" h264 encoding. At all. However, they do provide a wrapper for libx264, so that all h264 encoding actually goes via x264. - bugs for libx264 go to the x264 mailing list: http://mailman.videolan.org/listinfo/x264-devel (cf. http://www.videolan.org/developers/x264.html) - I strongly suspect the main problem that this bugreport describes is related to passing the correct options to libx264. Here ffmpeg and libav differ a bit. Your bug description still lacks the *exact* commandline options that you have used and what was exactly the commandline output of the 'avconv' tool. If you are developing your own application that links against libavcodec, then a stripped down version of your could could also help. Please note that the 'ffmpeg' tool is no longer maintained. - This is definitly an upstream issue that should be discussed at libav upstream. As you have noticed, the symptoms that you've described require an intimate knowledge of both libavcodec and libx264, which you generally cannot expect from an average Ubuntu Maintainer. Please use the upstream bugtracker at http://libav.org or the respective user mailing lists, which can be found at http://lists.libav.org/mailman/listinfo ** Changed in: libav (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/937678 Title: missing support for H264 profile main level 3.1 and security issue To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libav/+bug/937678/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
