[Dri-devel] 2D textures for video rendering
Hello guys, I hope you are not bored with me yet :( short target description: I have 2 cameras that muxed in their way to bt848, I have to draw contents of the cameras (while alternating the mux) to two windows with as few CPU usage as possible. my video card is i810. I get frames in non-shared memory buffer. As it turns out XVideo is not applicable since it can't deal with two windows simultaneously on one port card. so I am yours again :) Do you know whether 2D textures might be used as a surface to draw video on? Is DMA path of memory - texture implemented in i810 driver? (4.1.0) what do you think of this path at all? I just have no real expirience with OpenGL and I am afraid of various problems that might arise (for example RGBvsBGR, i.e. is BGR_EXT supported in hardware (i810) or it will just eat my CPU in converting? well, hope to get some answers, the project seems to be very simple for non professional view of my boss :( Michael Zayats ___ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel

System: Dual 550 Celeron, All-in-Wonder (original) PCI, 3D Rage II+. XServer is 4.1.0 with Gatos devel branch. Module is for 2.4 kernel. To use this on another card, you would have to enter the proper PCI id in the code. Oh yes, it uses the secondary register aperture, not the linear mapped aperture, but I don't think it makes a difference. Have not tried GUI dma, but it is quite similar. R C I'm sorry, but have no luck trying to install your module.
