I was using the default kernel that comes with Red Hat 8.0 with good results. xawtv-3.83 was working fine, i could use both overlay and grabdisplay modes. Then i switched over to kernel-2.4.20, with the Con Kolivas patch (ck4) applied: http://members.optusnet.com.au/ckolivas/kernel/ Now all of a sudden xawtv behaves very strangely. There's a delay of a few seconds when i start it; the overlay mode still works fine, but grabdisplay has big issues: - if i drag the window, the image stays in the same place - if i press F (full screen), it eats up the whole screen as it should but the actual image remains in place, small and unmoved Also, with the RH kernel, when i boot up the system, the sound starts to play in my audio system for a certain TV channel, even before using xawtv; i had to fire up and then close xawtv to get rid of the unwanted sound. Now, with this kernel, it doesn't happen anymore; i actually like that, but i wonder why it changed. These are the errors that i see in xterm: [florin@rivendell florin]$ xawtv This is xawtv-3.83, running on Linux/i686 (2.4.20-ck4) Warning: Cannot convert string "-*-ledfixed-medium-r-semicondensed--39-*" to type FontStruct Warning: Missing charsets in String to FontSet conversion Warning: Cannot convert string "-*-ledfixed-medium-r-semicondensed--39-*,-*-*-*-R-*-*-*-120-*-*-*-*" to type FontSet v4l: timeout (got SIGALRM), hardware/driver problems? ioctl: VIDIOCSYNC(int=0): Interrupted system call ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=15): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=5): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=4): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=1): Device or resource busy ioctl: VIDIOCMCAPTURE(frame=0;height=32;width=48;format=13): Device or resource busy no way to get: 1024x768 32 bit TrueColor (LE: bgr-) no way to get: 384x288 32 bit TrueColor (LE: bgr-) no way to get: 1024x768 32 bit TrueColor (LE: bgr-) no way to get: 384x288 32 bit TrueColor (LE: bgr-) no way to get: 384x288 32 bit TrueColor (LE: bgr-) [florin@rivendell florin]$ The timeout thing must be the initial delay. The image size are the errors occuring while going to full screen and back a few times. All this was tested in grabdisplay mode. Since xawtv worked fine before, i figured the problem could be in the kernel. Are you guys aware of any issues with v4l in 2.4.20? Could the ck4 patch be the cause of it? This is the relevant part of my modules.conf: alias char-major-89 i2c-dev options i2c-core i2c_debug=1 options i2c-algo-bit bit_test=1 alias char-major-81 videodev alias char-major-81-0 bttv alias char-major-81-64 tuner pre-install tuner /sbin/modprobe bttv options bttv radio=1 # options tuner debug=1 My card is a Hauppauge WinTV.
