I've been using NVIDIA Shield TV + Google Duo + Logitech C920 webcam with great success to video chat with family for several months. I highly recommend this setup to anyone who has patience and some technical know-how. I sideloaded Google Duo (arm64-v8a nodpi) as well as the Set Orientation app (to keep the video in landscape). I also use a bluetooth mouse to help navigate the screen - it is very helpful for selecting which contact to call, as well as for answering incoming calls. A prior thread mentioned success using the app AutoInput to answer calls, but I haven't tried this since the mouse works well for me.

Unfortunately the Shield 7.2 update caused the C920 to be waaaay zoomed in at all times, so the other party can only see a small part of my couch now. There are no relevant settings that I can adjust.

Does anyone have any ideas on how to force the webcam to be fully zoomed out at all times?? I'm hoping that an app exists that can force this functionality in the background, similar to how Set Orientation forces Duo to be in landscape mode.

I tried a variety of cross-platform (Android/iOS) video conferencing apps today in an effort to find a replacement for Duo, in case the problem cannot be fixed. As I'm completely Google branded, and because of the overall quality of the experience, I was most content with Duo. However, to help the community, and to give hope to those that want a similar setup, here is what I found:

- Facebook Messenger (and the Lite version) did not work; wouldn't connect to the camera.

- TrueConf worked well on my end, but my mom could hear her echo badly (this was the only app that had poor echo cancellation in my experience), plus the video doesn't expand to fill the whole screen.

- WhatsApp seemed to work well, but was vetoed by my mom because there isn't a native iPad app yet (only iPhone). You can reportedly use the WhatsApp web interface on the iPad, but she wasn't willing to try this.

- Skype works well (Lite version kept crashing), but I'm unable to answer calls with my mouse (maybe AutoInput could fix it?) - not too big a deal, just have to call them back.

- Viber also works well, but can't answer calls, similar to Skype.
