Any way to play a mpeg or even a avi movie within a OpenGL context using
SDL ?
And what do you guys think of HawkNL. A cross-platform network lib. ?
It looks nice and fully featured and has coverage by flipcode and
therefore a lot of users. It uses it’s own threads though. Anyway to
integrate or let it cooexist with SDL ?
I have seen ParaGUI, it looks really good. Although it’s draw functions
are completely based on SDL atm.
Do the SDL blitting ect. Functions also work within a OpenGL context ?
most of that i cant answer, i do know however that you cant use SDL 2d drawing routines when you set GL mode. There are GL techniques and functions to draw 2d but because of how GL works internaly, it cant give you normal access to the video buffer when its initialized.----- Original Message -----

Has there been any talk of an invisible framework of 2D drawing
function replacements when you use OpenGL under SDL? For instance,
SDL_Init() would set up functions invisibly using function pointers,
etc. I’ve seen similar trickery done other places.

Well GL isnt setup until you set the video mode with the flag SDL_OPENGL,
but as far as what your saying, i have heard nothing. I would be inclined
to doubt that anyone would make a “wrapper” for the GL API to do 2d drawing
with the conventional SDL 2d drawing function names because 2d SDL code and
the code to do 2d blits in GL are night and day as far as function
parameters and how they operate. But who knows! It would be pretty cool if
they pulled that off so that it was “seamless” in that you didnt know it was
gl doing the blitting.> ----- Original Message -----

Seems you are new to the list, please check out glSDL by David
Olofson at http://olofson.net/mixed.html. It does everything you
said.

Well, although it’s outside the scope, you could use glSDL for that. Someone (either (gl)SDL or the application) would have to deal with OpenGL state management, though, or any (gl)SDL calls will screw up subsequent OpenGL rendering.

Yeah. There’s a simple example in my smoothscroll demo as well…
