Hello RC,

thanks for your input!
-ac null prevents audio playback successfully but then -identify doesn't 
show enough audio properties. In my script I also check ID_AUDIO_NCH and 
ID_AUDIO_CODEC to make sure the files have an audio track. I should have 
mentioned that earlier.

Yesterday I ended up using mplayer -endpos .1 -vo null -ao null -frames 
1 -identify "${1}" in the script following Reimar's suggestions.

Sebastian
