Do existing video apps use TCP? I'll Wireshark next time I use Zoom. Seems like TCP is never going to perform well for low latency applications.
If you have bandwidth to spare, you can optimize for latency by using UDP and sending a lot of duplicate packets, or you can do something smarter with error-correcting codes if bandwidth conservation becomes an issue. The danger is sending too much and incurring queueing delay somewhere.
