videoin causes blue screen of death

bug open misc legacy

guest 10/05/08 - 09:47

Hello everyone

I have installed VVVV on two xp pcs.

The following problem happens just in one of them:

The moment i "move over" the videoin control with the mouse pointer - Windows crashes to the blue screen.

This also happens when I load the videoin help (sample file).

On both computers - I have DX9:
DirectX 9.0c (4.09.0000.0904)

dxdiag finds nothing.

Is it something with DShow? Is it a separate component ?

The dump says something about mcdevice.sys

Thanks

helo guest,

we like to blame those rare bluescreens on failing hardware drivers. so please make sure you have latest drivers for your graphic card and camera.

also tell us which camera and graphiccard you are using on both machines. maybe someone has specific experience with your hardware.

Well, in fact, there are two virtual cam's installed.
They are screen-capture-as-webcam-input software:
Luminositi SoftCam
and
MagicCamera Capture

The funny behaviour of all this is:

  • Creating the videoin control - ok
  • Moving the mouse on the input points - ok
  • Clicking on the input points - ok - i see the values, and i also see the list of devices: SoftCam and MagicCamera. (Currently no real webcam connected)
  • Moving the mouse over the control, or clicking one of the output points - blue screen

Now, I am trying to uninstall this screen-capture software:
But one of them - SoftCam - stays forever in the list of "webcams" in all applications.

Maybe you can help me with this:
How do I remove a certain "virtual webcam" from the windows webcam's list? Uninstall didn't make it for this SoftCam.

Of course, this issue is a candidate for the cause of blue screen: In the other computer (the stable one..), there are currently no webcam connected nor virtual webcam installed.

(I also upgraded MS Windows Media Player from 9 to 11, upgraded DirectX, but these did not solve the problem)

More information:
The webcam - is a philips PCVC690 - not connected at the time of crash.
The graphic card is - ATI MOBILITY RADEON 9600. I have manually upgraded it's driver to the latest, lately. But there is no other occurence of the symptom, other than vvvv-videoin.

Thanks
Israel

hola,

the funny behaviour you describe is quite seriously just as it is. only when evaluating the videoins output the videocapture driver is actually initialized internally. and there it seems to fail.

  • How do I remove a certain "virtual webcam" from the windows webcam's list? Uninstall didn't make it for this SoftCam.

hmm..evil. you could browse through the registry and delete all references to SoftCam. however, do this at your own risk. or try to contact the makers of softcam or install a newer version of that sofware..

good lukc.

sadly now I have to report the same problems. bluescreen with videoin.

specs:

win xp sp2
logitech quickcam 9600
actual pentium
ati radeon hd 3650
vvvv 40beta17

... and a fresh installed system including latest drivers!

the bluesceen reports something like lvuvc.sys Address error - the bluesreen disappears a lot to fast to get the hole error message.

link | m9dfukc 27/08/2008 - 21:49

hmm, shit now I have to get a new cam asap. anybody with the same cam around, can you confirm that error?!

Edit: Ok, seems that this is a know issue based on terrible logitech camera drivers. I hope I will find a workaround - maybe with generic drivers - otherwise I have to buy me a new cam tomorrow :(

link | karistouf 28/08/2008 - 09:46

yesterday a bluescreen crash on videoIn with beta17...

video IN is a dvcam, just playing with fiducials and pete deinterlace plug in...
i have virtual splitcam installed but not used

i m XP... could that be due to SP3 ?

cheers , :-)

link | m9dfukc 28/08/2008 - 11:24

nobody here uses the Logitech QuickCam Pro?

link | m9dfukc 28/08/2008 - 14:23

now tested VirtualDub and there everything seems to work! doesn`t virtualdub also use directshow ? why does it work there and not in vvvv? anyway ... is there a way to remotecontrol virtualdub ... everything I wanna do is save triggered videostills in a folder for further processing them in vvvv?!

Edit:
Ok, I realized that it maybe would be to much overload to use virtualdub for just make a still - anybody knows a good and remoteable (via udp ok osc) little capture programm to save still images from the imput stream?

link | m9dfukc 28/08/2008 - 15:19

...because I got more and more away from the actual topic I opened a new thread here.

link | m9dfukc 28/08/2008 - 20:07

@joreg: hmm, I tested my cam in graphedit and there everything seems to work fine! Doesn't that me that it also should work in vvvv?

link | joreg (vvvvgroup) 28/08/2008 - 21:03

graphedit is a hint but not the whole truth.
there are still different ways to render the image and the exact rendering technique used in vvvv cannot be simulated in graphedit.

if you have mediaplayer classic and in the playback-output options you select VMR9 (renderless) and "Use texture surface and render video in 3D" that should come pretty close to vvvvs rendering mode.

then restart mpc and file->device and check your cam.

link | m9dfukc 29/08/2008 - 00:38

thanks for the tip joreg, will try that tomorrow. I also think about a workaround - using something like split cam and route that into vvvv (works with split cam but the software only supports pal resolution) ...is this a good idea or rather a performance killer!?

link | m9dfukc 29/08/2008 - 13:41

Hi Joreg, tried your suggestion and in mediaplayer classic with the mention settings everything works fine! so I wonder a little what the problem is and what causes the bsod - any tips!?

link | joreg (vvvvgroup) 29/08/2008 - 14:15

hmm..can you join ##vvvv?

jup - I am in #vvvv right now

link | ramos 11/09/2008 - 00:15

hi there,

its the same problem (with the same camera) at my pc now.
started with a very old philips webcam and the vvvv40beta17 and directX from aug2008 on WinXPpro everything was fine.
then i installed the "logitech quickcam pro 9000 pro" with the newest drivers from logitech (installer called qc1180.exe).
after that vvvv crashes with bluescreen when starting the video-output (on CamShiftTracker help.v4p for example).
now, after deinstalling the logitech-driver, the problem is gone...
now the pro9000 is working as DirectShow "usb device".

with virtualDub there has been none of the problems all the time.

hth,
best regards
ramos

link | joreg (vvvvgroup) 11/09/2008 - 00:35

and how about beta18?

link | ramos 12/09/2008 - 11:16

with beta18 its the same story:
with logitech-driver -> bluescreen
without logitech-driver-> camera is working as 'usb-device'

link | joreg (vvvvgroup) 13/09/2008 - 20:54

with beta18 without logitech-driver working as usb-device..how well? the problem with beta17 was that it was too slow. but this could be fixed with beta18. what else would you need the logitech-driver for then?

link | m9dfukc 13/09/2008 - 22:00

hi joreg,

beta18 doens't fix the slowing down of the system for logitech quickcam 9000 pro. sadly the cam is now already used in the installation so I can't give more informations at the moment ... but in a month or so I will get the cam back then I can make some more tests.

... another problem is that without the logitech drivers all the 'extra' cam options are not available.

best andreas

@joreg - maybe we see us next week, I still need to get my cam back (but it's not that hurry)

Hi there,

I hope this thread hasn't died yet.
I get the same prblem using the built-in cam on my Nexoc E619 (aka Compal IFL90/Sagem 2090 etc...).

Whenever a pin in VideoIn is clicked vvvv freezes. Its even impossible to kill the process in the taskmanager. Logout doesn't help either, so I have to restart the whole machine, which is a major turnoff.

The cam is a Sonix, don't know which one though. Found no newer drivers than the ones provided by the laptop manufacturer.

System specs:
XP Pro SP3
.NET installed
DX 9 latest

Deactivating the cam and using another one (Philips TouCam Pro II in this case) solves the crashing problem. Of course I would prefer not having to carry that around...

Can this be fixed by vvvv? I don't expect anybody at Sonix to burst into tears and write new drivers if I told them (actually I wouldn't know what's to fix).

Alternatively I'd suggest to start a compatibility list.

ps: besides: just took my first steps with vvvv. nice work so far guys :-)

link | joreg (vvvvgroup) 26/11/2008 - 23:34

helo fluff,

you are using beta19.1, right?
hm...really hard to deal with those problems.
@m9: do you have your cam back meanwhile? probably i could have another look at it...and maybe that could solve fluffs troubles also..

link | fluff 26/11/2008 - 23:50

hi joreg,

used 18 and 19.1
(forgot that cause I had posted before but the server died on me and I had to write again)

link | m9dfukc 27/11/2008 - 01:38

hi joreg - I;m really busy atm, but I can borrow the cam in the beginning of next month.

link | lasal 29/11/2008 - 15:16

Hi
an other problem with the web cam, runs very slow, or freezed.

mac book pro 15" sp3,
ati radeon x1600, updated
vvvv 40.17, 18, 19, 19.1 (the same problem)
the latest bootcamp drivers installed.

thanks a lot

link | joreg (vvvvgroup) 11/02/2009 - 22:02

@m9dfukc:
think i got the little bugger. so i have beta>20 running with the quickcam pro 9000s 11.8 driver. but still only with 5fps@1600x1200 so thats the same as with the generic windows usb cam driver. but this seems just to be the specs, as the cam reports the following:

 I420 1600x1200 - 1600x1200 Granularity in X:1 Granularity in Y:1 @5 to 5fps
