Avidemux padá

Zdravím.

Snažím se digitalizovat video z 8mm kamery. Zdárně se mi povedlo nahrát ho do počítače pomocí :

mencoder tv:// -tv driver=v4l2:input=2:width=640:height=480:device=/dev/video1:audiorate=4800 
-o test.avi -oac copy -ovc lavc -lavcopts vcodec=mjpeg

V avidemuxu jsem to trochu prostříhal a chtel jsem to uložit. Nastavil jsem video na mjpeg, audio na AC3, filtr na deinterlace a když dám "save" avidemux spadne. V konzoli je přitom toto:

Goodbye...

Dělá to, podle všeho, hlavně když vyberu nějaký kodek, co má v závorce (lavc). Tušítě někdo, kde je problém ?

To jsem psal já ... to není bordel, to je modulární!
