I tried that, and all I got was segfaults..
$ mencoder mf://*.JPG -mf w=800:h=600:fps=25:type=jpg -ovc raw -oac copy -o 
output.avi

Could not find matching colorspace - retrying with -vf scale...
Opening video filter: [scale]
The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.
Why do we get NULL??
