Bug#238100: XVideo workaround for SDL apps
FWIW, I found a workaround for the problem I reported, working for
applications using the SDL library (this includes both mjpeg tools and VLC,
can't say for other video apps).
From the SDL FAQ on their website (www.libsdl.org) :
Q: How do I disable XFree86 XVideo acceleration?
A: You can disable all YUV hardware acceleration by setting the environment
variable SDL_VIDEO_YUV_HWACCEL to "0".
This works for me.
Notes to Branden Robinson :
1) First and foremost, thank you for your maintainance of the humongous
XFree set of packages. I am perfectly aware of the amount of work it
entails, and I do *not* criticize it ! Far from it ...
2) The above workaround might help to pinpoint the problem. Since you have
marked the bug "upstream", I presume you have submitted it. Could you pass
the info along ?
3) I didn't report libxv1 as broken in 4.3.0-5 ; I reported it broken *for*
*me*, *and* saw that users of other cards submitted similar reports. I
agree with you that it might be problems in individual card drivers ;
however, it might also be caused by a new assumption of the libxv1 about a
function which happens to more or less well supported by various cards drivers.
