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
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:
The funny behaviour of all this is:
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)
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.
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.
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..
sadly now I have to report the same problems. bluescreen with videoin.
win xp sp2
logitech quickcam 9600
ati radeon hd 3650
... 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.
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 :(
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?!
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?
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.
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.
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.
@joreg - maybe we see us next week, I still need to get my cam back (but it's not that hurry)
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.
XP Pro SP3
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 :-)
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
