Hello, i am writing a driver for my webcam and i am testing it with xawtv and gnomemeeting. I have two problems: 1) the window xawtv uses to display the frames is not resized to a particular resolution that xawtv successfully asked with the appropriate ioctl. I have to do it manually. Any idea? (I don't think the problem is the window manager). 2) The frames are grabbed using the YUV422-16bit format (original video), but when xawtv try to display them, the colours vary from green to purple only (i am not an expert, but i think the u or v value is setted to 0). 3) Gnomemeeting shows just the first captured frame even if the VIDIOCMCAPTURE and the VIDIOCSYNC commands continue to work in the right way (as debugging messages say). Did it ever happen to someone ? Below is the output from the driver after xawtv starts (i hope this may help): w9968cf.c: Opening the Video Blaster WebcamGo, minor n. 0... w9968cf.c: [w9968cf_start_transfer,680] Starting the isochronous transfer (153600 bytes/frame)... w9968cf.c: Video device is open. w9968cf.c: Invalid IOCtl: 0x80585600. w9968cf.c: [w9968cf_ioctl,1129] VIDIOCGCAP successfully called. w9968cf.c: [w9968cf_urb_complete,500] Got interrupt, but the camera is not streaming. w9968cf.c: [w9968cf_stop_transfer,715] Isochronous transfer stopped. w9968cf.c: Video device closed. w9968cf.c: Opening the Video Blaster WebcamGo, minor n. 0... w9968cf.c: [w9968cf_start_transfer,680] Starting the isochronous transfer (153600 bytes/frame)... w9968cf.c: Video device is open. w9968cf.c: Invalid IOCtl: 0x80585600. w9968cf.c: [w9968cf_urb_complete,500] Got interrupt, but the camera is not streaming. w9968cf.c: [w9968cf_stop_transfer,715] Isochronous transfer stopped. w9968cf.c: Video device closed. w9968cf.c: Opening the Video Blaster WebcamGo, minor n. 0... w9968cf.c: [w9968cf_start_transfer,680] Starting the isochronous transfer (153600 bytes/frame)... w9968cf.c: Video device is open. w9968cf.c: [w9968cf_ioctl,1129] VIDIOCGCAP succe ,1151] VIDIOCGCHAN successfully called. w9968cf.c: [w9968cf_ioctl,1165] VIDIOCSCHAN successfully called. w9968cf.c: [w9968cf_ioctl,1165] VIDIOCSCHAN successfully called. w9968cf.c: [w9968cf_ioctl,1165] VIDIOCSCHAN successfully called. w9968cf.c: [w9968cf_ioctl,1165] VIDIOCSCHAN successfully called. w9968cf.c: Invalid IOCtl: 0x800476C6. w9968cf.c: [w9968cf_ioctl,1522] VIDIOCGFBUF successfully called. w9968cf.c: [w9968cf_ioctl,1175] VIDIOCGPICT successfully called. w9968cf.c: [w9968cf_ioctl,1334] VIDIOCGMBUF successfully called. w9968cf.c: [w9968cf_mmap,1094] mmap method successfully called. w9968cf.c: [w9968cf_ioctl,1151] VIDIOCGCHAN successfully called. w9968cf.c: [w9968cf_ioctl,1175] VIDIOCGPICT successfully called. w9968cf.c: [w9968cf_ioctl,1175] VIDIOCGPICT successfully called. w9968cf.c: [w9968cf_ioctl,1175] VIDIOCGPICT successfully called. w9968cf.c: [w9968cf_ioctl,1175] VIDIOCGPICT successfully called. w9968cf.c: [w9968cf_ioctl,1175] VIDIOCGPICT successfully called. w9968cf.c: [w9968cf_ioctl,1235] VIDIOCSPICT successfully called.
