[MPlayer-users] stripes in image with (x)mga and ffmpeg on G200

Mon Jan 28 01:42:03 CET 2002

Hello!

First I would like to state how satisfied I am with mplayer.  It gives
me performance at least equal to Windows Media Player on my machine
and has just ditched my last reason to occasionally boot windows :-)
Thanks for your excellent work!

One problem remains, though.  I have a divx file that gets thin
horizontal black stripes in the right half of the screen when played
with "-vo (x)mga -vfm 5".  When played in fullscreen or with -vo xv or
-vo x11 or without -vfm 5 it runs fine but considerably slower.

I tried with latest CVS as well as 0.6, gcc 2.95-4 and 3.0.3, always
the same problem.

I have a K6-2 500 and a Matrox G200 AGP card with 8MB SGRAM.  I run X
4.1.0 with the Matrox 1.4.3 drivers, although I also tried the Xfree
builtin driver with the same result.  My soundcard is a Creative SB
Live! running the stock kernel drivers.

My distribution is an up to date Debian woody (testing) with custom
compiled kernel 2.4.17 and libc 2.2.4, gcc 2.95-4, as and ld
2.11.92.0.12.3.

I have uploaded a dd'ed chunk of the avi and the text of this email to 
ftp://mplayerhq.hu/MPlayer/incoming/stripes.avi
ftp://mplayerhq.hu/MPlayer/incoming/stripes.txt

A friend of mine with a G400 could play the file with the same options
without problems, so this might be G200 specific.

Any help would be greatly appreciated, I will gladly provide more
information if necessary.  Below are the outputs of the mplayer -v run
as well as lspci -v and cat /proc/cpuinfo.
Thanks a lot

Diego Biurrun
