Comment 5 for bug 162664

I'm not sure if this is related or not. On my setup:

15:19 alexjb@alexjb-desktop/x86_64 [Desktop] >cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=7.10
DISTRIB_CODENAME=gutsy
DISTRIB_DESCRIPTION="Ubuntu 7.10"

15:21 alexjb@alexjb-desktop/x86_64 [Desktop] >dpkg -l mplayer
ii mplayer 2:1.0~rc1-0ubuntu13.1 The Ultimate Movie Player For Linux
ii xorg-driver-fglrx 8.452.1-1 Video driver for the ATI graphics accelerato (envy installed)

I get flickery video playback with gstreamer, totem and mplayer. It looks very much like the video redraw is out of sync with the screen refresh. I experimented with the -vo option of mplayer and got the following results:

xv, gl, gl2, sdl - flickers horribly
x11, ggi - works, nice stable display
dga - crashes X
xvidx, xover - no driver loaded

So I don't think it's a problem with the low level driver, just some of the display modes don't sync while others do.

I currently have set my ~/.mplayer/config to:

15:24 alexjb@alexjb-desktop/x86_64 [Desktop] >cat ~/.mplayer/config
# Write your default config options here!
vo=ggi

As a work around. I've also uninstalled totem-mozpluging to use the mplayerplugin
