How to change Chromes media device API
I am trying to acces a webcam through WebRTC in Chrome.
Everything works on most PCs but on some it just shows a black screen.
Drivers and everything is installed and a little test program from the webcam manufacturer shows a video stream on all PCs.
In Chrome under chrome://media-internals you can look up some information about the media devices used in chrome.
On the PCs, that show a valid video stream, Chrome is using Direct Show as the device API. On the PCs, that show a black screen, Chrome is using Media Foundation as the device API.
How can I change the device API Chrome is using to acces the webcam?

This seems hardware related, not about programming. There's just one WebRTC API for all devices (emphasis on 'web'). Unless you're attempting to fix Chrome by building a custom version of Chromium? If so, please include more detail.

Chrome recently switched to MediaFoundation for capture, see the comments in
https://bugs.chromium.org/p/chromium/issues/detail?id=849636#c10
about how to test whether that particular camera works or not. If it does not work with MediaFoundation you should file a bug specifying the camera model so it can be blacklisted. Trying the same camera in Firefox on https://webrtc.github.io/samples/src/content/devices/input-output/ might give an indication about the model.

I will try it with Firefox and with the -disable-MediaFoundation tag on monday. But the PCs on which the webcam is working on, are running the same version of Chrome. I doublechecked that.

Can you gather more information about the device (manifacturer, model name) and file a bug at crbug.com please? That sounds like the device needs to be blacklisted. Please post a link to the bug here.
