[MPlayer-users] RGB image sequence -> AVI problems

[sebaaihb at mailbox.tu-berlin.de]

Hi all,

I am trying to convert a sequence of 500x500 RGB  images to an AVI, but the 
resulting AVI is only black&white when I use a codec other than -ovc wrgb
I tried both jpeg and png with the following commands:

 mencoder \*.jpeg -mf on:w=500:h=500:fps=15:type=jpeg -ovc wrgb -o output.avi
-> that looks fine, but the movie file is huge

mencoder \*.jpeg -mf on:w=500:h=500:fps=15:type=jpeg -ovc lavc -lavcopts 
vcodec=mjpeg -o output.avi
-> back quality black&white only, but really small file 

What am I doing wrong? Is there a way to tell mencoder to encode the images to 
a color movie?
I pasted the output of mencoder when encoding with -ovc lavc at the end  of 
the mail.

Thanks for all tips,

Sebastian
