Bug 688

Summary: SDL_DisplayFormat fails when using OpenGL
Product: SDL Reporter: Alexei Tereschenko <second_jin>
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED INVALID QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: HG 2.0   
Hardware: x86   
OS: Windows (XP)   

Description Alexei Tereschenko 2009-01-26 21:12:13 UTC 
Test example "testsprite".

Add a macro SDL_OPENGL to the "videoflags" variable in testsprite.c.
(173) videoflags = SDL_SWSURFACE | SDL_ANYFORMAT | SDL_OPENGL;

Run the example. It exits with errorcode 1. The error appears in:
LoadSprite() -> SDL_DisplayFormat() -> "Couldn't convert background:
Empty destination palette". With cmd params "-fast" or "-hw" the result is the same.

Without SDL_OPENGL it works well.

This isn't actually a bug, you can't use the SDL 1.2 blit API with OpenGL enabled, although the error message is terrible. :)
