I meant that mp4save writes an mp4 file, but the mp4info only shows a 
video track and the hint track for the video - no audio at all.


I read that .mp4 does not support all audio files. Thus - what 
video/audio format does app_mp4 support? What happens if the SIP client 
uses a non supported codec - will asterisk's transcoding features be used?
