[MPlayer-users] weird color bug in -mf, cvs version

Hello -- I'm seeing a very weird color artifact on some frames read
with -mf. I copied the last frame of the sequence, added some text to
the copy, and then copied it about 10 more times (just so the frame
sits on screen for a few moments).
Playing it back with -mf, the 10 identical frames have some sort of
flashing color thing going on. It's pretty odd.
Running the attached script will download the two frames and copy
the 2nd one 9 times. If you then run mplayer on 1) just the identical
frames, and 2) all of the frames, you (hopefully) will see the flashing.
The color seems to shift up by half a frame, creating a ghost image of
the lower half of the frame. The lower half of the image is left without
color. This alternates with every frame, which creates the flash.
I would suspect a video driver problem, except it happens with "-vo x11"
and "-vo xv", AND it shows up in video created with mencoder. This is
all with a cvs build as of yesterday.
btw, no editorial comments on the video content, please. ;)
