If it’s only video then as I had explained above its one of two things.
- The communication isn’t perfect some packets are being delayed or dropped which can cause issue. The ST live video control is very sensitive to errors and delays. Try a faster connection and reboot the hub and camera.
- Your phone doesn’t support the codec parameters as the video tile depends on your phone capabilities.
I’m assuming that your basic configuration is correct, i.e. Your camera doesn’t use RSTP ports. I.e. The link you’re getting in live logging works in VLC. If so then it’s one of the above. If not then first you’ll need to get that fixed
