Download Android SDK and put it under a known location. Get the
appropriate commandlinetools package from this page. Then, extract
it under ~/Android/.
mkdir -p ~/Android/Sdk
cd ~/Android
cp ~/Downloads/commandlinetools-linux-6858069_latest.zip .
unzip commandlinetools-linux-6858069_latest.zip
After this, we have to set up the build environment, accept android
licences, and build scrcpy from the dev branch.
export ANDROID_SDK_ROOT=$HOME/Android/Sdk
~/Android/cmdline-tools/bin/sdkmanager --sdk_root=$ANDROID_SDK_ROOT --licenses
cd /tmp
git clone https://github.com/Genymobile/scrcpy
cd scrcpy
git co dev
First, install dependencies.
sudo apt-get install ffmpeg libsdl2-2.0-0 adb gcc git pkg-config meson ninja-build libavcodec-dev libavformat-dev libavutil-dev libsdl2-dev openjdk-11-jdk
These commands should suffice to build scrcpy, tho Android being Android, you never know.
meson x --buildtype release --strip -Db_lto=true
ninja -Cx
Create a v4l2-loopback device.
sudo modprobe v4l2-loopback
On the phone, enable USB debugging, and install OpenCamera on your
Android device. Connect via USB, make sure to confirm USB debugging
once Android asks, and launch OpenCamera. In it, go to Settings > On screen GUI > Immersive Mode and select Hide everything. Camera
controls should disappear after a few moments of inaction when you go
back to the camera.
Now we can launch scrcpy:
ADB=/home/g/Android/Sdk/platform-tools/adb ./run x --v4l2-sink=/dev/video0 -N -S --lock-video-orientation=0
Note: currently this seems to leak memory, see this issue.
This will expose /dev/video0 as a v4l2-loopback device.
The server will start listening. I have so far tested this with Zoom and Jitsi on Firefox, and also OBS from Debian stable repositories (22.x, AFAICT). Cheese doesn’t work.
I have automated the camera streaming, you can checkout the script here https://github.com/imneonizer/android-webcam
