(Trying again, now that I think I have my list subscription straightened out) Has anyone got a setup anything like this working: - Recent Hauppage "WinTV-Go model 190" board (the '878 chip has a Conexant name/logo, if that matters) - bttv-0.7.63 driver - xawtv-3.43 - Redhat 6.2, XFree upgraded to 4.0.2. - 2.2.19 kernel built from RedHat's upgrade for 6.2, "kernel-2.2.19-6.2.1.src.rpm" (this kernel comes pre-patched with (some version of) the "new" i2c driver) After connecting an NTSC color camera to the composite input I get: $ v4lctl snap jpeg 640x480 foo.jpg v4l: oops: got sigalarm ioctl: VIDIOCSYNC(0): Interrupted system call ioctl: VIDIOCMCAPTURE(0,fmt=7,size=64x48): Device or resource busy ioctl: VIDIOCMCAPTURE(0,fmt=13,size=64x48): Device or resource busy grab: no match for: 640x480 24 bit TrueColor (BE: rgb) and in /var/log/messages, "insmod ./bttv.o bttv_verbose=1" results in these responses to v4lctl: Apr 22 02:40:10 viola kernel: bttv0: resetting chip Apr 22 02:40:10 viola kernel: bttv0: irq: SCERR risc_count=03826808 Apr 22 02:40:10 viola last message repeated 4 times Apr 22 02:40:10 viola kernel: bttv0: aiee: error loops Apr 22 02:46:35 viola kernel: bttv0: resetting chip Apr 22 02:46:35 viola kernel: bttv0: irq: SCERR risc_count=03826808 Similar failures and messages result when using xawtv itself. I don't really want to watch TV, just capture stills from an NTSC video camera connected to the composite input. Any hints? Reading through bttv-driver.c, it's obvious that "irq: SCERR" is the chip signaling an error of some kind. Any idea where to find a Bt878 datasheet these days so I can investigate further myself? (No joy at conexant's useless web site). (If someone were to send me a datasheet, I'll be happy to add some comments to bt848.h ...) Thanks for any assistance...
