[MEncoder-users] Assertion `picture_number<rcc->num_entries' failed.

[Dominique Dumont]

Hello

I'm trying to encode a short mpeg movie clip (received by satellite
with vdr) with this command:

mencoder 'vdr_ at CYCLISME_#3A_LE_DAUPHINE_LIBERE_2006-06-10_001.mpg' -oac mp3lame -lameopts preset=120 -vf pp=ci,crop=688:544 -ovc lavc -lavcopts vcodec=mpeg4:v4mv:vbitrate=1000:mbd=2:trell:vpass=2 -o 't_vdr_ at CYCLISME_#3A_LE_DAUPHINE_LIBERE_2006-06-10_001.avi'


The first pass works fine, but the second pass fails at the end with:

mencoder: ratecontrol.c:676: ff_rate_estimate_qscale: Assertion `picture_number<rcc->num_entries' failed.


The full output is:

mencoder 'vdr_ at CYCLISME_#3A_LE_DAUPHINE_LIBERE_2006-06-10_001.mpg' -oac mp3lame -lameopts preset=120 -vf pp=ci,crop=688:544 -ovc lavc -lavcopts vcodec=mpeg4:v4mv:vbitrate=1000:mbd=2:trell:vpass=2 -o 't_vdr_ at CYCLISME_#3A_LE_DAUPHINE_LIBERE_2006-06-10_001.avi'

IS there any way to avoid this problem ?

Thanks
