Description David Zaslavsky 2022-02-24 00:14:08 UTC
When I install Zoom from the ebuild, my webcam video does not show up in the app. I see a black screen where the video feed is supposed to appear, both in the settings page and in meetings. The symptoms are the same as https://bugs.gentoo.org/715106, but this is NOT resolved by setting USE=bundled-libjpeg-turbo, so as requested in that bug report, I'm creating a new one. (I actually did experience that bug at the time when it was current, and I fixed it by setting USE=bundled-libjpeg-turbo at the time. The video worked for a while, then stopped working again roughly a few months ago.)

I've tried reinstalling Zoom with each USE flag enabled and disabled (just in case), I've tried resetting my user-specific configuration settings for Zoom, and I've tried installing a couple of older versions going back as far as 5.8.6.739, the oldest version currently available in Portage. None of that makes a difference.

I went to Zoom's website https://zoom.us/download#client_4meeting and downloaded their Linux client, version 5.9.3 (1911). That actually _does_ work: I see my webcam video appearing within the app, as expected.

$ curl -O -L 'https://cdn.zoom.us/prod/5.9.3.1911/zoom_x86_64.tar.xz'
$ md5sum ~/Downloads/zoom_x86_64.tar.xz 
029ae0593aae58dfcc4403e9fe907505  /home/diazona/Downloads/zoom_x86_64.tar.xz
$ tar -Jxf ~/Downloads/zoom_x86_64.tar.xz -C ~/.local/opt/
$ ~/.local/opt/zoom/ZoomLauncher

Reproducible: Always

Steps to Reproduce:
1. emerge =net-im/zoom-5.9.3.1911
2. Open Zoom either through the desktop shortcut or by running `zoom` on the command line
3. Open the settings page in Zoom and go to 'Video'
Actual Results:  
The area which should show the webcam video is black

Expected Results:  
That area should show live video from my webcam

Comment 1 David Zaslavsky 2022-02-24 00:21:12 UTC
Oh I forgot to include this:

$ equery uses net-im/zoom
[ Legend : U - final flag setting for installation]
[        : I - package is installed with flag     ]
[ Colors : set, unset                             ]
 * Found these USE flags for net-im/zoom-5.9.3.1911:
 U I
 + + bundled-libjpeg-turbo : Use bundled libturbojpeg instead of media-libs/libjpeg-turbo
 + + bundled-qt            : Use bundled Qt and icu instead of system-wide libs 
 - - opencl                : Use OpenCL for virtual background support (virtual/opencl) 
 + + pulseaudio            : Add support for PulseAudio sound server

Comment 2 Ulrich Müller gentoo-dev 2022-02-25 06:33:20 UTC
I could reproduce this once, but then I couldn't any more.

What I did:

Reproduced the problem with zoom-5.9.3.1911 following the steps in the original report:

(In reply to David Zaslavsky from comment #0)
> 1. emerge =net-im/zoom-5.9.3.1911
> 2. Open Zoom either through the desktop shortcut or by running `zoom` on the

> Actual Results:  
> The area which should show the webcam video is black

Downgraded to previous version:
5.9.1.1380 -> black
5.8.6.739 -> video

At this point I thought that the issue appeared in 5.9.1.1380, and upgraded again to confirm this. However, the problem is gone now:
5.9.1.1380 -> video
5.9.3.1911 -> video

I'll investigate further.
Comment 3 José María Fernández González 2022-04-29 09:47:10 UTC
I don't know whether it is related.

I upgraded yesterday from net-im/zoom-5.9.6.2225-r1 to net-im/zoom-5.10.4.2845-r1 . With the former, blur background for webcam video worked out the box, but with the latter black webcam video is broadcasted and shown when blur background is set.

After some tests, I got it working through the usage of /opt/zoom/ZoomLauncher instead of /usr/bin/zoom
Comment 4 Ulrich Müller gentoo-dev 2022-11-12 12:52:39 UTC
Is this still an issue in zoom-5.12.6.173?
Comment 5 David Zaslavsky 2022-11-20 22:48:39 UTC
Sorry, it took me a while to get time to check this. But yes, it is still an issue in the latest version.

$ emerge -pv net-im/zoom
[ebuild   R   ] net-im/zoom-5.12.6.173  USE="bundled-libjpeg-turbo bundled-qt pulseaudio -opencl -wayland" 

I also checked that if I download Zoom 5.12.6 directly from Zoom's website (using the same procedure described in my first comment) and open it, the video appears properly there. So whatever is going on is still a quirk of the Gentoo installation of Zoom, not an intrinsic bug in Zoom.
