[Xpert]Fw: video rendering using HW scaling

[Michael Zayats]

I know that it is a newbie question, but everybody should start at some point :)   I have video frames captured 25fps in 24bpp RGB. I want to draw them in X11 window. I can't just overlay from framegrabber(bt848) to the framebuffer (because of camera switches that take place in a middle, frames are filtered in my app). Hardware scaling is needed badly. I don't know if it's important, but my framebuffer is running in 32bpp and I couldn't make it run in 24 bpp (i810).   to summarize: I have buffers with 24bpp RGB and want to put it fast and CPU-economically in X11 window.   Can somebody advise me? XVideo? undocumented XvPutImage? some simple code skeleton for it?   thanks for any help,   Michael
