I'm not sure if we have the same problem, but here's mine: Whenever I start fxtv now, the window is black and I get: ioctl(METEORSSIGNAL, -65535) failed: Invalid argument Trying to change the input results in: ioctl(METEORSSIGNAL, -65535) failed: Invalid argument TVCAPTURESetInputDevice(): Called when cature is on TVSCREENStartVideo called with continous capture already running...ignored ioctl(METEORSSIGNAL, -65535) failed: Invalid argument SetCaptureMode called when contin running SetTransferMode called when contin running SetRegionGeom called when contin running SetPixelGeom called when contin running TVSCREENCapConfigure() failed: Continous is running Using "mplayer -tv on:driver=bsdbt848" gives me a really messed up image of whatever is on the attached camera, with scanlines, wrong colors, etc., and at about 1Hz. However: starting gnomemeeting and enabling local video feed works fine, as does the simple bktr_grab example that grabs an image. I've rolled back the driver, and a version before 8/10 works, while one after 8/11 doesn't. I'm thus pretty sure that the following commit broke things: > nectar 2003/08/10 16:04:55 PDT > > FreeBSD src repository > > Modified files: > sys/dev/bktr bktr_core.c > sys/i386/isa spigot.c > sys/kern sys_process.c > sys/pci meteor.c > Log: > Add or correct range checking of signal numbers in system calls and > ioctls. > > In the particular case of ptrace(), this commit more-or-less reverts > revision 1.53 of sys_process.c, which appears to have been erroneous. > > Reviewed by: iedowse, jhb > > Revision Changes Path > 1.126 +1 -1 src/sys/dev/bktr/bktr_core.c > 1.60 +2 -0 src/sys/i386/isa/spigot.c > 1.113 +2 -2 src/sys/kern/sys_process.c > 1.63 +2 -0 src/sys/pci/meteor.c Try rolling back your sources before 8/11 and see if that fixes things for you, too.
