Oki, for some reason it now works (I’ve restarted the server, that’s the only thing I know I did). Works in the way that I hear the sound, but don’t see the video…
This is true both in the .avi and the AVI file with .m4v extension (I set all .m4v files to avi in the DB). For some reason, there’s now (?) no video stream in the output:
Try updating the file in the db so that has_video is 1.
