I have encoded different personal DVD's with the CLI interface of handbrake in order to embed the 3 or more languages of the video. When I open the mp4 file in quicktime I've got the following error message: "An invalid sample description was found in the movie". But I can still open the movie with VLC without any problem. Do you know what's going on?
I use the latest version of the CLI and my command looks like this:
Thanks Rodney for the suggestion. I have renamed my mp4 files in .3gp file but without success. This seems to be a known quicktime issue (http://discussions.apple.com/thread.jsp ... 0�) without a clear fix. All the best, E.
AC3 is not a valid audio codec for mp4 files!
I'm surprised VLC plays the file. You have to use AAC audio with mp4 file format. And as jbrjake said in order to have all the audio tracks you need to specify one -a with them separated by non-numeric digits.
I started to have this problem with 0.9.2 after encoding AAC+AC3 audio. Working too late at night I did not realize that handbrake had not reset the extension from mp4 to m4v. Changing this after the fact works and the files that would only play in VLC now work in quicktime player.
