Run multiple containers in parallel

[mfoglio]

Hello,

I am using pyav to stream a few rtsp videos on the same device. I need to access some of the data coming from the streaming and decode the actual frame only if a few conditions arise:

get packet --> compute conditions --> if conditions are satisfied decode the frame

It is my understanding that multiple containers cannot work in parallel because of GIL, therefore I tried to create Process for video ingestion. However, that does not seem to be a solution because VideoFrame objects cannot be pickled. I would need to pickle them to add them to a queue so that they can be later retrieved and decoded only if the abovementioned conditions are satisfied.

How can I solve this situation? My goal is to ingest multiple streams in parallel so that I can fully exploit the CPU.
