I am trying to create a CHD image of a laser game from a .ogg file and a .m2v file.
I started by converting them to an .avi file with the following.
$ ffmpeg -i game.m2v -i game.ogg game.avi
Then i tried to create the CHD with the followin.
$ ./chdman createld -i game.avi -o game.chd
I got the error message unsupported audio. I am guessing I need some flags for ffmpeg to make it work.
