Yup, checked that and chanded it accordingly. I tested it with all Xv ports which i assumed to correspond to the video devices i have (which seems to be a wrong assumption because of the results i got). Anyway - if i start the program it displays some image but it is half offscreen and half set to the side, as a completly misconfigured overlay and looks pretty close to the overlay (guessed upon the coloring as xv images have a slightly darker gamma than overly here). The video is display for some seconds and then it locks up for some seconds and the process repeats. After launching the app the X server is no longer responsive and often can not be restarted cleanly at all. In short - it does not work. (BTW - i think you mixed up the order of some of the parameters of the XvPutVideo() call in that modified rootv.c). Any more ideas? Eventually i can test it with a system with an Nvidia card to see if it works anything different... > Not sure I completely understand you here, but any program can use the > XvPutVideo() call. There are various reasons why the author of xawtv chose Just to go for sure - i guess the XvPutVideo call is not just an X-server integrated version of the overlay+clipping functionality like xawtv does?

Exactly, and in the case of xawtv (and my kvdr) i use it to display consecutive grabbed frames which works but with the mentioned limitations. _______________________________________________ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
