IOMega Buz working, but overlay sometimes "screws up" ...

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



I have the IOMega Buz working under RedHat 7.2 with kernel 2.4.9-31.  I
was surprise that I didn't have to patch some of the drivers, although
they seem to be fairly "updated" under 2.4.9-31 anyway.

One interesting issue I am having is with xawtv, both the included 3.54
in 7.2 as well as Rawhide's 3.73.  For some reason, after running for
awhile, I will lose the normal ~640x480 picture and can only "get it
back" if I reduce the xawtv window so it is 128x96!  If I try to make it
big again, it looses the picture (sometimes with a little, single scan
line at the very time)  I have _no_idea_ why it happens, but a
_cold_reboot_ (complete power-off) seems to be the only way to fix it.

But even when it happens, I can still use the lavrec and other
MJPEGTools fine to capture.  It looks like some kind of "overlay" issue,
although I'm not a regular V4L user (this is my first setup).  "-debug
2" didn't seem to give me anything different than normal.  I think it
could be the result of me running another DGA, SDL or other app though. 
E.g., I got it once after running MPlayer with SDL output, although I
couldn't reproduce it after rebooting.  So it might be random as well.

My mainboard is the Tyan Tiger MP (S2460) with the AMD760MP (762+766
north+south) chipset -- dual-Athlon.  My video card is the nVidia
GeForce3 Ti200 with the nVidia closed source drivers.  I've tried the
1.0-2313, 1.0-2802 and 1.0-2880 drivers and don't make a difference
either way.
