first off, thanks to everyone for the help so far... but the
questions just keep coming:
i think it's best if i explain exactly what im working on before i
ask more questions. i'm working on an app that analyzes a live video
feed. in response to the feed, i'm drawing a number of little
widgets on a canvas, they all need to redraw at 30fps, and be dragged
around and resized by the user. currently i'm compositing everything
in the canvas... i'm starting to ponder moving all this to opengl.
i'm hoping you guys can offer a run down of the pros and cons. how
well can i integrate a number of opengl contexts into a single
window? or if i do one, will i run into bottle necks loading lots of
fairly large textures?
other questions: i just realized my video frame is backwards, is it
possible i've attached the texture backwards? or am i looking at it
from the behind?
eventually it crashes by spawning a few thousand threads all waiting
on mpqueues. anyone seen this problem with opengl? seems to only
happen if i keep swapping out the texture with glTexSubImage2D... if
i set the texture once then it'll run for hours. do i need to
dispose of the old one before i add the new one?
i think that's it for tonight... i'm sure i'll come across more in
the coming days.
thanks again,
mike
