I wanted to use the x264 codec to encode some DV-video I've shoot with my camera. Mencoder that is installable through the RPM manager doesn't seem to have been compiled with this option. I checked out MPlayer source from SVN

I tried to compile MPlayer/MEncoder by hand. But I had som troubles when trying to compile it. I get the following error:

Anyone who can help with this? Configure went fine and it Identified my CPU correctly.

Or is there some other way to encode with x264?

Have you tried the mencoder, x264, and all the libx264s from the PLF repos?

I never thought of the fact that there was a plf version also. I used the standard Mandriva version, and now that I changed to the plf version it actually works nicely. Thanks!
