Date: Tue, 24 Aug 2004 06:16:32 +0200 From: Christian Biere Subject: [SDL] YUV Overlay vs. XV_AUTOPAINT_COLORKEY I have a problem with SDL's YUV Overlay support using X11 Xv. Some people reported that they get nothing but a black screen. I've compared the output of xvattr they've sent me with the values I get here. It turned out that XV_AUTOPAINT_COLORKEY was disabled. By enabling this feature everything works fine.
