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.
