Hi Natalia,<br>
<br>
Thank you for your response. Yes I was kind of thinking among the same
lines, and try to search the list. Some of the converstations did
discuss the issues with vic crashing with FC1 and FC2. I believe
starting from FC3 and FC4 the Video For Linux 2 drivers were built into
the kernel and resolved several issues with the cx88 series. The latter
AG2.3 and AG2.4 releases also resolved some issues with using the V4L
compatability with V4L2 drivers, so I it works well. However what I am
seeing is a little different, where the streaming works, but one window
would stop sending, and muting/unmuting does not help, and restarting
the vic causes the window to broadcast a green screen. <br>
<br>
Thank you for the tip about reloading the video capture modules, but I
have tried to use tvtime to verify that the card still works after the
green screen. So I think the reboot solves more of an AG issue than a
driver issue. However, as Doug pointed out it could be the manner in
which the AG toolkit uses a compatablity tool for V4L2 instead of the
natives, for very good reason (namely users with Quickcams will have
difficulties as V4L2 support is still beta). I believe he will be
releasing a possible native V4L2 controls for the AG in the coming
week, which may help in what I'm currently faced with. <br>

0.0.3 version by that time and I could hardly make it work (only with a kernel

people did afterwards, search that thread (there are many concerning cx88 chip)
to find some more information. Try a capture card with an 878
chip instead?.</font></div><span class="q">

video using VIC in fedora 3/4</div>
<div><br></div>Hi,<br><br>I've been debugging a non-responsive vic window
problem for days, what happens is that for the first 5 mins, I get perfect
motion on all 3 cameras. All of a sudden one of them will freeze up. Stoping
the session and staring it again causes vic to show a green window, and
essentially render that capture card useless. Still works under tvtime, just
not with vic. I am almost hitting a brick wall, ie. tried almost everything I
could to find out if it was my server(dual core dell 380s), capture card
(Hauppauge Winttv 401 c88xx version), linux (fedora 4), or the vic software.
<br><br>Step 1: was making sure that the Wintv cards were all good, and had
not problem running simultaneously for hrs, a fair amount of burn in tests
were done, the tv cards all seem to be able to run at capture mode for hrs
with no problem. <br><br>Step 2: was to see if vic was kind of not so nvidia
friendly, the video capture server has a dual head 128mb PCI-E, which I've
heard people find not so great to work with under linux. I personally did not
find any such problems, running at 1600x1200 just fine, perfect response time
and etc. But just for kicks I brought out a dual xeon dell box I had lying
around, with more than ample horse power with a pretty simple video card,
probably an intel i810 type of a card. Unfortunatley I faced the same
problem.<br><br>Step 3: Fedora 4 versus Fedora 3. So I decided to try Fedora 3
with some spare hard disks. Fedora 3 seems surprisingly easy to setup AG with,
unlike the mountain I had to climb for Fedora 4. However, it seems to also
mysteriously freeze one of the vic screens, after which every session would
produce a greed screen on the frozen vic. Only a reboot will fix the green
screen problem. But then after 5 mins of starting AG, I'm back to the frozen
screen problem.<br><br>Step 4: AG2.3 versus AG2.4, I was very excited when I
saw that the screen did not freeze up after five minutes. But alas after about
15 mins or so I get a frozen window, and will show up as a green screen
everytime after that. Only a reboot will fix that problem, and would
eventually freeze up again.<br><br>Step 5::Move 1 capture card to another
machine, as it seems to be able to handle 2 just fine. But it appears that
even in this case VIC would cause a frozen screen on one of the windows. And
the usual green screen appears. The one with just 1 works perfectly.
<br><br>So I'm kind of running out of ideas, since the capture cards on their
own pass the burn in test. Software capture tests all pass. The VIC however
mysteriously causes a frozen screen followed by a green screen in next vic
startup. <br><br>Any suggestions would be most welcome. Kind of running out of
hair to pull aswell. Thanks in
advance.<br><br>Proshanta<br><br><br></span></blockquote>
