USB 3.0 HDMI Capture Devices don't work any more

[chris109]

Same problem (Image freezes after a view seconds) with several devices connected to several notebooks / PCs.

Tested Capture Devices:

* Elgato Cam Link- https://www.elgato.com/de/gaming/cam-link
* Magewell USB Capture HDMI Gen 2 - http://www.magewell.com/usb-capture-hdmi
* XCSOURCE HDV-UH 60 - http://www.hdcvt.com/index.php/product/des?id=165

Problem occurs with

* Ubuntu 16.04.4
* Ubuntu 18.04

Earlier versions of Ubuntu don't have this problem. Test where done with a variety of applications: OBS Studio, Cheese and more.

Tested signal is 1920x1080, 50p from a "Sony CX405 Handycam".

The whole hardware setup is used regularly. So there is no problem with cables or the camera.

I can't locate source of the problem. All I know is it is related to the
two Ubuntu versions, mentioned in the report and something they have in
common. I hope very much someone can find the time to at least look into it
and can confirm the problem.
