FLAC in .mov container not working

Description

Hey, a file encoded with the following command

ffmpeg -i input.mov -i test.mp3 -vcodec mjpeg -acodec flac test.mov

Does not play in VLC player, reporting:

"VLC does not support the audio or video format "ms��". Unfortunately there is no way for you to fix this." (The format tag characters here pasted correctly from the error window).

This video plays correctly, but no audio.

This should work, right?

Thanks

ms is not a FLAC file... Are you sure you can put FLAC in mov?

Hey, I'm not 100% sure FLAC is legal in a .mov file, but this article states it is:

http://en.wikipedia.org/wiki/Comparison_of_container_formats#Audio_formats_supported

My own libavcodec code is able to read and decode the file fine (and it comes in as FLAC encoded audio).

I've attached test.mov that is a mjpeg movie with FLAC audio in a .mov container that has this error.

Ok looking into this more it seems like ffmpeg.exe isn't writing the correct codec tag for this format (some issue with Vorbis also). May not be a VLC bug afterall.
