Hans de Goede fixed bug #495
When running boswars: http://www.boswars.org/ on a machine with intel
integrathed graphics it crashes when it tries to play the initial theora
splashscreen video:
X Error of failed request: BadAlloc (insufficient resources for operation)
Major opcode of failed request: 140 (XVideo)
Minor opcode of failed request: 19 ()
Serial number of failed request: 25
Current serial number in output stream: 26
boswars: xcb_xlib.c:41: xcb_xlib_lock: Assertion `!c->xlib.lock' failed.
Aborted
I recognized this problem from a few years back, when I encountered it while
working on the Xv blitter for xmame. The problem is that for some reason
creation the Xvport and XvImage succeeds, and failure (lack of resources / hw
capability?) is only indicated during the first XvPut[Shm]Image. I've written a
patch for SDL using the work around for this I developed for xmame (and which
is still used successfully in xmame after many years of usage).
I'll admit it isn't very pretty, but after investigating several possibilities
this was the best option, any other fixes would need changes to the SDL api and
abi.
