[FFmpeg-user] Audio not playing in Quicktime Player

Thanks to all, I consider the issue solved.

The solution is: I either have to 
- use the MOV container, in which case I can copy the mp3 stream to the output; or,
- use the MP4 container, in which case I have to convert audio to AAC.

Best regards, Gabriel
