The following drop box link contains an archive of two capture files, one with AC3 audio, the other with E-AC3 audio: https://www.dropbox.com/s/23lmw5vru3816sa/streams.tar.xz There's not likely to be much that we can do about this, unless it's worked around by the VLC developers or fixed in FFmpeg. From what I understand, FFmpeg 2.3 is ABI compatible and shouldn't cause issues, but it sounds like it is (I suspect it's responsible for the gstreamer problems that have been discussed on the dev mailing list as well). You could report it to FFmpeg (they have a trac bug tracker and also #ffmpeg on Freenode) and if that doesn't result in a favorable output, report it to VLC, if you want to speed up the process. *Maybe* rebuilding VLC and gstreamer1.0-libav will help, but that would still indicate a problem in FFmpeg. We can try it, though. vlc-2.1.5-2.mga5 submitted for Cauldron. Please let us know if it helps. Yeap, problem solved, I can read *AC3 audio. Nice job. Thank you so much. Thanks for the report! I'll try rebuilding the gstreamer ffmpeg/libav packages too. Status:

Created attachment 5299 [details] Vlc logs when problem occurs Description of problem: After updating ffmpeg and libav packages, VLC is no longer able to handle E-AC3 streams. In France, DTTV on HD channels is encoded in extented AC3 format, while Satellite HD channels use AC3. Streams captured on Sat are still readable while those captured on Terrestrial are now crashing VLC. The problem occured after upgrading the following packages: ffmpeg-2.3-1.mga5.tainted.x86_64 Thu 17 Jul 2014 11:25:09 PM CEST lib64swscaler2-2.3-1.mga5.tainted.x86_64 Thu 17 Jul 2014 11:25:08 PM CEST lib64avformat55-2.3-1.mga5.tainted.x86_64 Thu 17 Jul 2014 11:25:08 PM CEST lib64avfilter4-2.3-1.mga5.tainted.x86_64 Thu 17 Jul 2014 11:25:08 PM CEST lib64postproc52-2.3-1.mga5.tainted.x86_64 Thu 17 Jul 2014 11:25:07 PM CEST lib64avcodec55-2.3-1.mga5.tainted.x86_64 Thu 17 Jul 2014 11:25:07 PM CEST lib64swresample0-2.3-1.mga5.tainted.x86_64 Thu 17 Jul 2014 11:25:06 PM CEST lib64avutil52-2.3-1.mga5.tainted.x86_64 Thu 17 Jul 2014 11:25:05 PM CEST How reproducible: Direct play of french DTTV HD channel form capture card crashes vlc File reading of french DTTV HD capture crashes VLC (log included) Steps to Reproduce: 1. start vlc from konsole in verbose mode 2. Open capture device in VLC. 3. Select HD DTTV channel 4. vlc crashes Or 1. start vlc from konsole in verbose mode 2. Open HD DTTV channel capture file 3. vlc crashes Two examples of 10s capture files will be included after bug submission (AC3 and E-AC3)
