Hi, I'm just testing out vMix for use in a school for simple production work.

As a test I've been asked to set up a video presentation, with some cut slides and a live feed from a webcam.
The first parts of this are non problem, it's just the webcam i'm having problems with.

First test was just using the built-in webcam in the laptop i'll be using, this seems to work with no problems.
Next step, grabbed a Logitech HD C510 Webcam from another computer as the subjects obviously won't be in control of the mixing.
After setting the capture input settings i am informed that "No combination of intermediate filters could be found to make the connection."
With error data:-
DirectShowLib-2005
AddNewInput

After a few searches there are a number of sites saying that this is a codec problem, but the drivers are installed and logitech software loads and displays fine.
Is there an easy fix for this? or an obvious problem in using this webcam with vMix?
Alternatively, can you recommend a webcam model that is known to work.

Obviously i'd like to work with something better than a webcam, but as this is to be run from a laptop which doesn't have USB 3.0, so a BlackMagic Design Intensity Shuttle isn't really an option, and i'm not sure the cheaper options on capture devices, like a compro C200 are worth bothering with in this scenario? (i can get my hands on a panasonic video camera if that is likely to work).

Thanks for any assistance you can offer on this,
MK

Apparently there are "No capture filters" according to MPC-HC.
I find this odd, as i can capture from the built-in webcam in vMix...

I've checked that directx is up-to-date, just going to install directx sdk to see if that makes a difference.
I'm running Win7 Enterprise x64 if that makes any difference.

OK, so downloaded normal MPC, and that works, after running it, MPC-HC also works...

I have put an order in for a C510 to test with. Will let you know what I discover in about a weeks time.

Hi MK,

Just received the C510 today and after a bit of testing have worked out what the issue is.
It will be fixed in vMix 2010 v9 due out soon. In testing I discovered that the camera can output full frame rate 720p when the drivers are installed (and with the vMix fix) which is much better than the LifeCam Cinema which only seems to get around 20fps.

The fix should also resolve issues with other webcams that use the I420 codec.

Regards,

Martin
