[Gnash-dev] OpenGL buffering question

[Rob Savoye]

On the assumption there are people on this list that have more OpenGL 
experience than I do (I don't have much), I have a question. My current 
working version of the plugin appears to play movies, but instead of the 
rendered frames, I get the hardcoded triangle/square graphics instead. 
The odd thing is the code to draw the hard-coded graphic is never 
executed. It's like it's stuck in the double buffer, and when I swap 
buffer, I get an older stored image ? Maybe I should check in my current 
version after a little more cleanup.

I figured out the problem with the player was a mutex locking up. For 
some odd reason, the mutex as accessed by the player thread was 
non-functional, although it worked just fine in the plugin thread. I 
replaced the use of SDL_Mutex with Mozilla's PRLock, and now it works 
fine. I've been reading through the NSPR API docs, and I think I'm going 
to completely modify the plugin to use Mozilla's NSPR API for mutexes 
and threads instead of SDL on the assumption they're better supported 
within Mozilla.
