Hi again: I am running vstreamutil.c . When I lunch the program I got a window in black. I have another computer with the program sending images from the camera. I have seen that my program is sending RTP packets . But I don?t know if they are right or not. I receive the images with the program. When I open it I got a black window that turns green. And if a see the status I am receiving data. When I put the mouse over the window It closes and return this message : XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0" after 99 requests (98 known processed) with 2 events remaining. Could you help my?? Regards Jorge -------------- next part -------------- An HTML attachment was scrubbed...
