[MEncoder-users] First 111 frames duplicated

[double]

Hi,

If I transcode a wmv2,wmav2 video to whatever, mencoder will
duplicate the first 111 frames:
111 duplicate frame(s)!

As a result A/V is completly out of sync. Is there anything I can
to to prevent this duplicate frames on startup?

Command line:

mencoder http://doppelbauer.name/error.wmv -of lavf -ofps 25 -vf 
scale=320:240 -ovc lavc -oac lavc -lavcopts 
vcodec=wmv1:vqscale=2:acodec=wmav1:abitrate=128:autoaspect -mc 0 
-channels 2 -srate 44100 -o test.wmv >txt 2>&1
