SIGALRM on 0.7.x and weird 0.9.x behavior

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



hi,

I have 4 pixelview that used to work properly on xawtv, but hence I
upgraded and patched the 2.4.20 kernel, the /dev/video1 stopped working.
.. xawtv gives me this error message:

v4l: timeout (got SIGALRM), hardware/driver problems?
ioctl: VIDIOCSYNC(0): Interrupted system call
ioctl: VIDIOCMCAPTURE(0,fmt=15,size=48x32): Device or resource busy
ioctl: VIDIOCMCAPTURE(0,fmt=3,size=48x32): Device or resource busy
ioctl: VIDIOCMCAPTURE(0,fmt=4,size=48x32): Device or resource busy
ioctl: VIDIOCMCAPTURE(0,fmt=5,size=48x32): Device or resource busy
ioctl: VIDIOCMCAPTURE(0,fmt=1,size=48x32): Device or resource busy
ioctl: VIDIOCMCAPTURE(0,fmt=13,size=48x32): Device or resource busy

this error only comes up when I use 0.7.x.

I tried 0.9.x and there is no error messages, but when I run two xawtvs,
each one reading a different /dev/video, they keep "exchanging" the
captured imagens, causing a weird flickering picture... for example, the
first xawtv window show its own picture then the picture of the other
xawtv at 30 frames per second (15 its own and 15 of other).

I have to use 0.7.x, so, any idea of the xawtv error messages?

ah, I'm using xawtv 3.85

really thanks

Fabio Roger
