Most video streaming today is not served by UDP, but by TCP. Only live video uses UDP. Stored video (ex. Netflix) is all sent via TCP.

- nacs 11y ago> Only live video uses UDP Not necessarily. One of the largest live video streaming services, Twitch.tv, uses TCP for streaming.
- gafferongames 11y agoTwitch is not interactive so it can just buffer for a few seconds more and handle the typical worst case of TCP. It'd probably still be better over UDP but I'm not qualified to say that for sure. I'm sure the twitch.tv guys could chime in on their choice and inform us of the pros and cons for their situation. The correct choice is application specific.
