Product: SDL Reporter: Stefan Bradl <stefan_bradl>
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: 1.2.11   
Hardware: x86   
OS: Linux   

Description Stefan Bradl 2007-07-13 13:06:46 UTC 
I followed this tutorial for playing videos with sdl 
http://www.dranger.com/ffmpeg/ 
and found out that sdl crashes when I use 
SDL_SetVideoMode(...) with SDL_OPENGL.
Comment 1 Sam Lantinga 2007-07-15 07:26:09 UTC 
I believe this is fixed in SDL 1.2.12:
Couldn't create overlay: YUV overlays are not supported in OpenGL mode
Comment 2 Stefan Bradl 2007-07-15 12:57:33 UTC 
Tried out SDL 1.2.12 but the bug still exists
Comment 3 Sam Lantinga 2007-07-15 12:59:59 UTC 
Can you attach a simple test case that shows the problem?
Comment 4 Stefan Bradl 2007-07-15 13:07:28 UTC 
ok I'll try to make a little test case because the project where i found this problem is a little bit bigger...

Comment 6 Sam Lantinga 2007-07-15 14:34:51 UTC 
I'm taking a look at it now...
Comment 7 Sam Lantinga 2007-07-15 14:55:30 UTC 
So it is actually failing and returning a NULL overlay surface.  Whatever library you're using isn't checking the return value.  I fixed it so it isn't crashing in SDL anymore, but the application still crashes because it assumes that it got a valid overlay.
Comment 8 Stefan Bradl 2007-07-16 02:54:42 UTC 
but why fails 
SDL_CreateYUVOverlay() only when OpenGL is initialized?
Comment 9 Stefan Bradl 2007-07-16 02:59:30 UTC 
ah ok I understand...yuv overlays are generally not supported in in opengl...
Is there a workaround for this problem because I need to play videos in an OpenGL window.

Take a look at the glmovie test program in the SMPEG source
