It depends on the specific use case and requirements. Some popular live streaming protocols include:
- Real-Time Messaging Protocol (RTMP): This is a widely-used protocol for streaming audio, video, and data over the internet, and it is supported by many streaming platforms and encoders.
- HTTP Live Streaming (HLS): Developed by Apple, HLS is a widely-supported streaming protocol that uses standard web protocols to deliver video streams. It is designed to work well with varying network conditions and is supported by most major browsers and devices.
- Dynamic Adaptive Streaming over HTTP (DASH): Similar to HLS, DASH is a protocol for streaming video over the internet that uses standard web protocols. It is designed to adapt to changing network conditions and is supported by a wide range of devices and browsers.
- WebRTC: WebRTC is a technology that allows real-time communication directly between web browsers, without the need for a centralized server. It is a newer protocol, but it is gaining popularity due to its low latency and support for peer-to-peer communication.
Ultimately the best protocol for live streaming will depend on the audience, the platform, and the encoder you are using, as well as the network conditions.
VeerCast uses all these protocols, and allows the user to decide which one works best for you and your users.
