Video processing on live data.

📽️ VideoProcessor turns a computer into a 4k HDR capable live video processor by connecting a video capture card to a renderer and taking care of details such as conversion, timing and HDR metadata.

This allows advanced renderers to do things like 3D LUT, HDR tone mapping, scaling, deinterlacing and much more which can significantly improve image quality on most displays and beamers.

Capture cards cannot capture HDCP protected data, VideoProcessor can only process what can be captured.

videoprocessor's Issues

Other Declink cards working?

Hello, spending 500 € just for a test is a bit much, so I wonder if the seemingly very similar Deckling Mini Recorder 4k card might work just as well. https://www.mediatec.de/postproduktion/io-interfaces/blackmagic-decklink-mini-recorder-4k?gclid=Cj0KCQjw16KFBhCgARIsALB0g8KGXsF0LjMyVHmkgJG-p-gXG48X69Glu6aE9YediO8kmNCFAbJt2pEaAkeNEALw_wcB

Thx and greetings!

Hdr data doesn't show in videoprocessor anymore

Hi Dennis,

Thanks for your work, Videoprocessor is getting better and better.

I had an issue with Videoprocessor: it was working fine up till I had to reinstall windows 10, after I reconfigured all the data in the tab HDR (in the video processor gui color coordinates, maxfall and maxcll) no longer appear .

I don't know if it is related, but these information are no longer available in the vertex 2 osd. The source of these information is the vertex (like with the filter) or they should be extracted from the video stream?

Thanks if you have any suggestion

Why the madVR Render can successfully block the live frame from VP

Hi Dennis,
Thanks for your works, and I have sucessfully compiled your project and ran VP with the madVR Render(below 134).
When I run VP with the madVR Render(above 134), VP always show black screen. I try to change the frame format, alter timestamp, rename the process name, and reduce the bit counts. But no effect.
So I have not any way to let the madVR of high version running on the VP. Could you tell me some details about live source from capture card which madVR can detect.
Thanks if you have any suggestions.

Crash on source switch/source restart

Crash or no pickup on source change

Some source changes lead to a crash or the source not sending a support format to the capture card. Restarting the card does not help buy sometimes restarting the process does. Probably somewhere in the init of the EDID?
