PyStream evaluates adaptive video streaming by running Dockerized players on one host and using a virtual reverse proxy to delay each player’s requested segments according to its assigned network trace. Its PyShaper mechanism improves trace fidelity over Wondershaper: across 20 players and two ABRs, average error is reduced by 2–3×. For 64 players, savings are estimated at about 8% under assumptions.
