Why is RTSP Video Lagging in QGroundControl Daily (Master), but Works Fine in 4.4.3?

Hi everyone,

I’m facing an issue with RTSP video lag in the QGroundControl Daily (master) version.

I’m using the following setup:

1.Cube Orange+

2.SIYI MK15E remote controller

3.SIYI A8 Mini camera (RTSP stream)

** Problem:**
I have tested on both QGC 4.4.3 and QGC Daily (master build)

The RTSP video stream from the A8 Mini works perfectly in QGC 4.4.3.
But in the QGC Daily (master) version, the video lags heavily (8-10 seconds delay)
I haven’t changed anything : same camera, same RTSP URL, same hardware, same network.

What has changed in the QGC Daily/master branch that might be causing this RTSP lag?
Is anyone else facing the same issue with RTSP streaming in the Daily build?

Any ideas or known issues related to this would be really helpful.
Thanks in advance!
