Phyton is not right tool for the task. You are measuring nothing and learnt Phyton skills though generally useful but meaningless for this project. Almost all camcoders run A/V streams through some encoders to lower bitrate in order to be able to record on the slow media card; those that don't use very fast storage. Digital cameras use memory buffers and allow limited number of burst frames because of finite size of that buffer and writing to digital media post factum.I am developing a real time embedded processing application. A/V capture and processing all in real time. No need for display.
My processing is certainly less complex than video codec. I know the complexity of these codecs as I worked on the HW part of video and telecommunications processing in the.....90's.
I spent a few years of my carrier working in A/V capturing/encoding business Usually video and/or audio streams are transferred to CPU memory by DMA. If you worked with hardware you must know what I am talking about. I have no idea about video subsystem of Raspberry Pi and how to use it to your task. If 25 years ago most of work was done in assembly last 20 years I successfully avoid it using C and some inline assembly functions.
