The Pros and Cons of WebRTC
Advantages of WebRTC include:
- Adjusts the quality of the communication stream if network conditions change.
- Supported by major web browsers, including Google Chrome, Mozilla Firefox, Android, and Safari.
- Does not require third-party components or plugins and is free as open source software.
Disadvantages of WebRTC include:
- Users must establish their P2P browser connection, creating a bandwidth issue and limiting scalability.
- There are expensive maintenance costs when media must be relayed through a TURN or SFU server.
- Content distributors who wish to stream with a professional encoder and camera might find the adaptive bitrate streaming abilities of WebRTC limited.
