Hello. > I compiled&installed ffmpeg from svn
> I *have* libavformat-dev installed, and the wanted file is somewhere on my > harddisk: > $ locate libavformat.so.50 > /usr/olib/0.2.0/lib/libavformat.so.50.4.0 > /usr/olib/0.2.0/lib/libavformat.so.50 Ok, some comments on your installation: - If you installed ffmpeg from svn, you should remove packages ffmpeg, libavformat, libavformat-dev, libavcodec and libavcodec-dev since they are all replaced by ffmeg svn and will probably conflict if both packages and svn version are installed. - /usr/olib/0.2.0/lib/libavformat.so.50.4.0 This comes from the openlibraries project ( http://www.openlibraries.org ), not sure how it behaves... - If you installed ffmpeg from svn, you should have a libavformat located in: /usr/local/lib/libavformat.so.50 Then, check if your /etc/ld.so.conf file contains a line "/usr/local/lib". If it doesn't, add it (before the "/usr/olib/0.2.0/lib" line if there is one) and the do "ldconfig" as root. You can then make some tests to see where the problem is: 1) ffplay your_movie file 2) inigo your_movie file 3) try playing your movie file in kdenlive Also make sure you configured and compiled ffmpeg and mlt using the options recommended in http://kdenlive.sourceforge.net/downloads.php#requirements regards jb
