How to set specific format for videoIn (Skia)?

[zeos]

Hi vvvvolks,

yet another try with latest gamma preview :) I am having this Logitech BRIO, which apparently has also IR stream (NV12 encoded). One can see it in the supported formats output pin from the videoIn (MediaFoundation) node, but how can one set the node to use this specific format?

Not sure about the Media Foundation but if you use the VideoIn fron th CV pack you could do the following: RighClick > Configure > Show Prefered API > ANY and type in NV12.

here it works on the latest stable.

Other though is - been a long time an might be wrong but- as far as I remeber that camera comes with a software. You could also do the adjusmntes there and it will be saved on the camera.

Yes, I ended up using the OpenCV :) videoIn too.
Now I need to see if I can decode the NV12 stream, and if this is the IR / Depth one or not.

In any case, I tested the camera with C#/C++ test samples called “Frames” or something like that and indeed it does expose them.

cheers
