Hi, from the video you appear to be using VLC to replay the video. There are known problems with VLC and unencapsulated H.264 bitstreams (see the comments in the WARNING box here).
I'd recommend either using a different player (ffplay handles these streams fine), or writing straight to an mp4 file (which VLC will play). Seeing as you're using Python, the PyavOutput might be worth looking at, as it will write mp4 files directly.
