jonbendtsen@media:/jon_compiles_ffmpeg/ffmpeg$ ./configure --enable-gpl
--enable-libx264
ERROR: libx264 not found
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
installing the debian package now.
okay, so it compiled, but the same cmdlines doesnt work.
