How to measure jitter and loss of a codec transmission in python

I'd like to test the jitter and loss of an internet connection using python and some h264 encoded video.

I'm assuming I should stream mp4 from a server to a client. I know I could use ffmpeg to do this. But I'm not sure how I would measure the packet jitter or packet loss. The same applies to using python sockets to stream mp4.

What's the best way to analyse packets I've sent in python?
