Hello everyone! I'm a newbie on Linux OS. (excuse my English). I wanted to kindly ask you an opinion regarding an issue that I can't solve. When I export movies with kdenlive, exporting process reaches the end, and then get a message like this "consumer_avformat.c: video codec unrecognized libtheora - ignoring. The file can be corrupted"
This always occurs and creates files of 0 Kb.
Someone know any solution for this problem? The programm say that MLT can be corrupted....

Thanks to everyone.

Are you sure you have libtheora installed?
Also try using a different codec.

I don't know why, but now there isn't any problem.... all works well. Thanks!
