RBS 2017 Webcam #21

Closed lecler-i closed 5 years ago

lecler-i commented 6 years ago

Hello there, thanks for all the good work and detailed guide !

I have a RBS 2017 and everything is working but the webcam, all we all know.

But i noticed it works almost perfectly (at least it's not all green or black and have decent fps) using Slack or Hangout ! it's the only two website i figured it is working (even betetr than using a software).

I know nothing about codecs and webcam in general, but why is this so ? Would it be possible to use the same stream as they use on slack/hangout and create a "virtual webcam" from this good stream, to be able to use it on any other software / websites?

Sorry about this issue, it's not really an issue about the repo but more a question and some "ask for help" arround webcam workarround

Do you used Slack and Google Hangout in your browser? Chromium, Firefox or Chrome?

rolandguelle commented 6 years ago

I've tried https://www.cam-recorder.com/, works very slow with some defects in the video signal. Google Hangout works (slow) too, with the same problems.

Cheese works with 176x144.

The webcam issue is still open with 18.10, I put the browser / webview info in the unsolved issue / webcam section.

You can see the same thing just using any webcam viewer.

If I bump it up to 1080 in guvcview, I get the distorted image (Stealth late 2016 i7-7500U)

Even 720 isn't guaranteed

Any word on this? Still happening. And I don't see anywhere that has any possible explanation why.

After quite some time I found a fix for this (it could live with that because it worked with Zoom, but recently after a kernel upgrade artifacts started appearing there too).

I added

options uvcvideo nodrop=1

To /etc/modprobe.d/uvcvideo.conf

And reloaded the driver with rmmod uvcvideo, modprobe uvcvideo

To my surprise, even Cheese works now

Adding quirks=512 might also slightly improve webcam quality: https://wiki.archlinux.org/title/Razer_Blade#Webcam_2
