I would like to be able to tune the player buffer, so I can control for network irregularity. A few examples: As a conference live streamer, I want to have higher buffer in the player (30-40s) because latency doesn't matter as much, and the internet connection at the venue is always a challenge. As a global social live streaming site, I want to have a higher player buffer for users in locations that have bad internet infrastructure, and a lower player buffer for users in locations that have good internet infrastructure.
