The version of mencoder I currently have installed segfaults (immediately) when you ask it to convert x264-encoded MKVs to another format. One sample command-line would be:
Code:
mencoder -nosound -ovc libdv Puella_Magi_Madoka_Magica_720p_GG_-_06.mkv -o a.avi
This produces the following output:
Code:

Extracting the video track with mkvextract and then mencoding
that produces the same output.
I'm using a
very recent MPlayer checkout (I used Pat's SlackBuild, set USE_PATENTS to YES, and set the VERSION to 20110702). The version of x264 that I have installed, and that I've built MPlayer against, is the one currently on SBO: 20101023.
Can anyone else confirm whether this happens to them, or is it just me?
Incidentally, I'm wondering if the version of FFMpeg that the MPlayer configure script downloads might be at fault. The slightly outdated FFMpeg I installed from SBo (6.1) does not crash when converting the same file.
And no, I can't use either Alien Bob's Mplayer build or the MPlayer binaries included with Slackware. Neither is built against either libdv or x264. I need libdv as an output codec.
