[MPlayer-users] mermaid.avi: artifacts in mplayer, plays fine in xine

Thu Feb 19 08:14:38 CET 2004

I've uploaded to incoming the file mermaid.avi. This is the first 10Mb of an
AVI file that plays with artifacts in mplayer (-pre3 and -current) but
perfectly in xine. The chopped version won't play in xine, and has lost sound
in mplayer.

The artifacts are only actually visible right at the very end of the chopped
version. They only seem to effect objects that move down from the top of the
frame. I tried various encoder-bug settings in mplayer but it didn't work.

The effect is as if the codec copies chunks of white pixels from off the top
of the frame and blends them into what's already there.

I can provide more if necessary, but the whole file is 449 large. I have no
way of knowing what it was encoded with, so don't ask.

Here's the output of mplayer -v on the original full version:
