Hello, I want to convert a .3gp file to a .flv I've seen on Internet that this is a common problem, but I'cant find a solution. I get a .flv file twice as fast as the original and with no audio, I don't know how to fix this, does anybody knows a solution? sorry bout my english... Here's the line I execute... Ive already tried to specify the codec and etc etc etc etc but no way....
