# Zoom's Screen Sharing is tricky because |
|
# 1. I'd rather run it (or, any properity software) in containerized |
|
# environment (i.e., flatpak on Fedora 32), so big NO to the official rpm |
|
# 2. I have switched to Gnome Wayland recently and no intention to switch back |
|
# to X11, due to a few reasons like Firefox looks better on Gnome Wayland. |
|
# 3. RPMFusion's OBS is broken on my system for whatever reason. |
|
|
|
# After searching on the Internet and github for a while I found and tested the following solutions. |
|
# Reference: https://wiki.archlinux.org/index.php/Screen_capture#Wayland |
|
# Overall scheme: |
|
# a. Use OBS Studio+obs-xdg-portal to capture any Wayland Window |
|
# b. Use V4L2lookback to forward videos to as camera so that Zoom/Skype can use. |
|
# I have tried other combination listed the wiki, but most of them either |
|
# doesn't support Gnome Wayland, or cannot pipe the video to Zoom/Skype. |

# Step 2: Build flatpak |
|
## Install the SDK if you hasn't, the version may change in the future |
|
## so you can try to build and see the error about the rigth version. |
|
flatpak install flathub org.kde.Sdk/x86_64/5.14 |
|
cd com.obsproject.Studio |
|
flatpak-builder --force-clean build-dir com.obsproject.Studio.json --user --install |

cd com.obsproject.Studio.V4L2Sink |
|
flatpak-builder --force-clean build-dir com.obsproject.Studio.V4L2Sink.json --user --install |
|
cd .. |
|
|
|
# Step 3: build v4l2lookback |
|
git clone https://github.com/umlaeute/v4l2loopback.git |
|
cd v4l2loopback/ |
|
make |
|
sudo make install |
|
sudo modprobe v4l2loopback exclusive_caps=1 card_label=WfRecorder |
|
v4l2-ctl --list-devices # Optional: check the loopback device is ready. |
|
|
|
# Final: run the right OBS Studio |
|
flatpak make-current --user com.obsproject.Studio stable # The instructions above should install to the stable branch, ... |
|
flatpak run --user com.obsproject.Studio # ... and copied the compiled OBS Studio to the user installation. |
