I'm currently trying to build and package ffmpeg-2.5.1. I'm not looking to push it to the repos anytime soon though as there are quite a issues to contend with first. I don't know if gst-av and gst-ffmpeg will work with it, if it will run to slowly, consume too much RAM etc. Its just as a test.

Good news is binary wise it's built. I'm converting the latest debian sid package whilst trying to remain as close to the original package as possible. One aspect which is failing at the moment is the ffmpeg.install processing, in particular manpages. It can't install them because it hasn't built them. Checking config.mak, HAVE_POD2MAN is not set. The executable is in /scratchbox/tools/bin AND /usr/bin. pod2man from command line work fine.

Anyone got any suggestions?
