Control: tags -1 + patch First of all, I can see how you're busy, but if you think my problem is trivial, please just tell me so. If I'm sending a message saying "I don't know how to continue", even explicitly saying that I know this may not be what you need, a reply only saying "this is not what we need" is totally unhelpful. It shouldn't be too much effort to type the extra sentence "what you describe you did should have worked, did you try restarting the server?" (which I thought I did, but I suppose I didn't). A line like that helps more than you might think; it confirms that I was on the right track. Since I don't know much about the code or how it's supposed to work, that is good to know.
Anyway, a server which is unable to play any video 5 minutes after starting gives quite a strong motivation to fix things. So after I got a backtrace, I debugged the thing. The problem was that the result of intel_get_pixmap_private() could be NULL, but that wasn't checked. So I grepped for it and added checks to all calls of that function. The patch is attached. You will want to check if I'm handling it the right way everywhere, because I just guessed the proper course of action. Then again, most code would segfault without handling it, so perhaps most of these can't ever be triggered anyay (but I'm not too sure about that; it certainly can set it to NULL when calloc fails). Thanks, Bas
