Error with Raspberry Pi 4 & Camera Module v2 #87

Closed SteeveGL closed 3 years ago

SteeveGL commented 3 years ago

I tested with the code on master 344e824 on my Raspberry Pi 4 with Noir Camera Module V2 . I got the error AttributeError: module 'lib' has no attribute 'SSL_OP_NO_TLSv1_3'

Any ideal? I guess I have to update a library...

SteeveGL commented 3 years ago

I replaced the line balena-cam/Dockerfile.aarch64#L34 by

RUN pip3 install aiohttp aiohttp_basicauth==0.1.3 aioice==0.6.10 aiortc==0.9.11 numpy==1.15.4 opencv-python==3.4.4.19 pyOpenSSL==19.1.0 --index-url https://www.piwheels.org/simple

A package has a dependency to pyOpenSSL > 19.1.0, and that cause that error.

Now I get Video device is not ready. Sound like a progression.
