The problem is that ffmpeg head typically requires a newer version of x264 than what is packaged. > couldn't test MLT and kdenlive :P I have a script extracted from the old kdenlive build wizard that automates much of this including building x264 and libvpx from source as well. I will look into adding that here somewhere. > http://kdenlive.org/user-manual/downloading-and-installing-kdenlive/installing-source > > Comments welcome.

Therefore, the following are irrelevant for most users: --enable-libxvid --enable-libgsm --enable-libdc1394 --enable-libschroedinger --enable-libopencore-amrnb --enable-libopencore-amrwb libfaac is still fairly interesting thereby necessitating the --enable-nonfree. However, we should probably mention that is optional along with --enable-libvorbis and --enable-libtheora. > And thanks for the earlier answers which I understand now. > > Simon > > 2010/9/1 Dan Dennedy <[email protected]>: >> On Wed, Sep 1, 2010 at 1:27 AM, Simon A.
