Playing FLV files is not the problem, FireFox will do it fine. Again what I want to do is convert them from FLV to MPEG4. I tried to use FFMPEG code ffmpeg -i file_name.flv file_name.avi and at the end it comes back with 'file corrupt or truncated" I have used MOYEA FLV converter before on another platform and it works perfect. Since I switched to Ubuntu I am dedicated to it and until I find a native program (or one is written) I can only use what I know. [Wink]
