Ich habe avi und mov-Files von einer Digicam mit mencoder ausgelesen und dabei 
gibt es sehr viele übersprungene Frames, so dass der Ton viel zu schnell ist 
und am Ende mehr als 1 Minute Stille ist.

mencoder "$MOVFILE" -of rawaudio -oac mp3lame -lameopts preset=standard -ovc 
copy -o "$MP3FILE"

Was könnte man machen, dass der Ton synchron bleibt? Es ist ja keine konstante 
Verschiebung und wird immer schlimmer? Hängt das mit 29.970 fps zusammen?
