[MPlayer-users] mplayer crashes with mencoder-mpeg2-AVI-file

[Bernd Knorr]

Hi,

I created an AVI file (vcodec: lavc mpeg2video) with the following mencoder 
command (CVS-version of  20040614):

mencoder -oac lavc -ovc lavc -tv 
driver=v4l2:width=720:height=576:alsa:audiorate=48000 -lavcopts 
acodec=mp2:vcodec=mpeg2video:keyint=25:aspect=4/3:abitrate=128:vbitrate=10000:vmax_b_frames=2 
-vf lavcdeint -o test.avi tv://

When I to play this file with mplayer it crashes (see the output at the end of 
this mail).
The problem only occurs, if vmax_b_frames>=2.
Avidemux2 also has problems opening that file (hangs while "checking for 
B-Frames...")

If I output to mpeg-format or vmax_b_frames<2 everything is fine.
