aiortc
J'ai fait fork du projet aiortc pour la raspberry pi avec utilisation de l'encodage matériel :
https://github.com/jpiat/aiortc
peux tu essayer l'exemple examples/picam et me dire si ça fonctionne chez toi ?
pour installer (dans le répertoire du projet)
sudo apt install libffi-dev libopus-dev libvpx-dev libsrtp2-dev libavdevice-dev libavfilter-dev git clone https://github.com/jpiat/aiortc cd aiortc/ python3 setup.py bdist_wheel sudo pip3 install dist/*.whl cd examples/picam python3 webcam.py
Ouvrir un navigateur (chrome ou chromium sur PC ou chrome sur Android) sur un PC/smartphone connecté au même réseau :
http://ip:8080
cliquer sur start
Tentative d'installation sur Buster et Erreurs
J'ai du installer les paquets libavdevice-dev libavfilter-dev, mais voici le résumé de l'erreur obtenue après:
- erreur.txt
