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
