Hi, thanks for your code!

I fail to run your code as the gi package cannot be found. I understand it requires the python packages PyGObject and pycairo. The environment is a docker container of python:3.9.2-slim-buster.

On the Dockerfile I have the following install commands:

RUN apt-get update && apt-get install -y
RUN apt-get install ffmpeg libsm6 libxext6 -y
RUN apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-doc gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio -y
RUN apt-get install libglib2.0-dev libgstrtspserver-1.0-dev gstreamer1.0-rtsp -y

RUN pip install opencv-python
RUN pip install pycairo
RUN pip install PyGObject

and then I added also RUN apt-get install libcairo2 -y just before the pip commands and also other intents but they all fail with:

Any idea how to solve this?

Thanks!
