Hi all. I'm building an application that should do this: -render a video on the background (taken from /dev/video0, a v4l2 device, bttv device) - render (and update) a surface (with alpha transparency) upon it (let's call it DrawSurface).
Now i've no problems doing the two step by themselves, but i'm just getting confused choosing the best approach to do it together. Should i PlayTo the videoprovider directly onto the primary surface and than blit the DrawSurface upon redraw callbacks? should i playto the videoprovider on a separate surface (double buffered or not?) and than blit the videosurface, than the DrawSurface upon the redraw callback? For this purpose what would be the best solution: overlay or grabbing? Is overlay suitable for drawing a semi-transparent surface on it? Thans to anyone who would shed a bit of light in this chaos!
