Background Why choose Qt + MQTT for implementation? Initially, I used Electron + WebRTC + SRS for implementation, but WebRTC requires exchanging protocols, and obtaining protocol content in Electron’s WebRTC is done through Chromium, which is difficult to control. The key issue is that the Electron package is hard to manage, so I abandoned Electron. … Read more
