SDL YUV surfaces

SDL Development
1

Guys,
Any plans on implementing YUV surfaces ? It would be nice to have HW YUV
overlay with ability to put OSD by just using SDL blit functions. Right now
I’m forced to use custom built code to achive this and of course it does not
use HW acceleration…
For now it would be ok to use sw blits only( we can steal it from DFB ).
Thanks,

Not at the moment. If you’re interested in contributing this, make sure
your code works on all supported platforms and submit a patch to the mailing
list.

hi,
this normally happens if you try to write in space that doesn’t belong to you.
for example:
int x[10];
x[15]=12;

Your program crashed, and SDL caught the resulting exception in order
to clean up and return the display to a usable state. (If this isn’t
done on some platforms, the user may be forced to reboot if a
fullscreen application crashes.)

Use this (from a post by John Popplewell earlier today):

SDL_Init ( SDL_INIT_VIDEO | SDL_INIT_TIMER | SDL_INIT_NOPARACHUTE);

to disable the SDL parachute, so you can have your debugger of choice
trap the exception instead.
