I'm not sure if someone said this already or not, but the XvPutVideo simply displays incoming analog video into the drawable specified in the XvPutVideo call (some setup and configuration calls are req'd previous to calling XvPutVideo() ). If you wish to display "video in a window" on your linux box from an analog source, like a camcorder, then this will work - I use it all the time. It should not load down your system - it will take a bit of PCI bandwidth moving YUV across the bus, but it should use no CPU. This call will only work on certain hardware, depending upon the drivers available. It does work on an ATI All-in-Wonder Radeon and ATI All-in-Wonder Radeon 8500 DV with the GATOS drivers. Also, if you load the v4l module in your XF86Config-4, you will be able to use the XvPutVideo call on a video4linux device installed in your machine. If anyone knows of any other hardware this works on, please let me know. I'm not sure if that helped or not, but that's what XvPutVideo() does....
