Even on the fastest gpus that we could realistically use, railbird's video
processing pipeline can only run at about 2x real time. If we were to wait for
users to finish recording their tracking sessions to start uploading video to
our backend it could take hours for them to have complete statistics, at which
point they will likely have moved on to thinking about something else. The
obvious solution here is streaming, but unfortunately, pretty much every
streaming protocol in existence is optimzed to minimize latency at all costs.
They achieve this by adjusting the bit rate or dropping frames to synchronize
the stream closely with the recording time, whenever the connection bandwith
becomes spotty or cuts out momentarily. These sacrifices in the name of
