I download the latest android version from the official website - v4.4.3, and everything works fine to connect to rtsp video streaming via 4g, but the v4.4.3 version that I compiled by myself, which was compiled without any reported errors, does not connect to the video. What’s even more amazing is that after I installed the android version provided by the official website, my version works. Is it possible that the qgc official website left a hand and there is a stable version, after all, I compiled the process without any reported errors and got a package that is different from the official website? Can anyone tell me?
