Hi @Phil Londrico. Per today, WebRTC is the most used, and probably most widely-supported protocol for low-latency playback from a web browser. There are other solutions, all of them proprietary by third parties, and pretty much all of them based on websockets.
There are several initiatives to get low-latency over HTTP; probably the most known and discussed is Apple’s Low-Latency HLS (LL-HLS), of which the spec was made final just now in Mar/Apr. Then there’s LHLS with CMAF, an initiative from MPEG et al. And THEOplayer has developed HESP and is working hard on pushing this in the market. However, it’ll take some time before either of these will be ready for implementation in production environments. The entire chain (at least media server, cdn, and player, and sometimes also the encoder) must be updated to support low-latency. My guess is another 6-12 months, but that’s IMHO.
AFAIK Wowza has support for Apple’s LL-HLS and LHLS CMAF, but I don’t know of any player that supports either of these per today. And the CDN must also support certain features in order to convey the stream with low delay.
