Few Video Sources listed

Hi everyone,

I’m compiling my own version of qgoundcontrol based on Stable V4.0 version on my laptop. I discovered a question when I’m trying to use rtsp video stream, only ‘video stream disable’ and ‘integrated camera’ are listed. No UDP port or rtsp at all. I’m wondering how I may fix this.

Thanks in advanced.

Updating, I’ve fixed the few listed problem by changing the GST_ROOT in VideoStreaming.pri file. But a new problem came up.

I’ve tested the camera through VLC to ensure the rtsp address is correct: rtsp://
But no video is shown after entering this address into QGC.

Does anyone know how to fix this? Thanks in advanced
