This page documents the setup of a Linux system for screencasting
On Screen Display
Show Keyboard commands
When showing software it's usefull for the students to see which keyboard shortcuts are pressed. This on screen display (OSD) can be installed like this:
sudo apt install screenkey
will install the screenkey application. Run it from the taskbar:
Show Mouse Clicks
Stream Canon 5D via USB
Stream from OBS to a virtual camera source
We can't stream directly from OBS into Jitsi, BigBlueBitton, Google Meet, Skype, etc. For this wee need a virtual camera source.
sudo modprobe v4l2loopback devices=1 video_nr=10 card_label="OBS Cam" exclusive_caps=1 sudo apt install qtbase5-dev git clone --recursive https://github.com/obsproject/obs-studio.git git clone https://github.com/CatxFish/obs-v4l2sink.git cd obs-v4l2sink mkdir build && cd build cmake -DLIBOBS_INCLUDE_DIR="../../obs-studio/libobs" -DCMAKE_INSTALL_PREFIX=/usr .. make -j4 sudo make install
