We are facing a persistent issue with our church streaming. The issue is having a very pixelated photo/ghosting for the PTZ cameras only. Other fixed cameras are working fine. (see the attached)
I have contacted the manufacturer, and still no resolution. The issue is evident using Wirecast, on OBS, there is an issue of Interlacing, rather than pixelation.
The following has been done trying to narrow down the root cause:
1. New streaming PC (i7, 10Gen, 2.5GHz,16Ram, 6GB Geforce GTX 1660 Ti , Giga port, WAN speed is around 800Mbs Down/100 Mbs Up, 2 ms Ping
2. Lowered/Increased the Bitrate, FPS, I frame, Resolution, VBR/CBR whatever combination is out there
3. Ran live tests for more than 40hr, the issue is isolated with the PTZ cameras only.
4. In OBS , tried all interlacing options
I have two theories:
1. The firmware of the PTZ cameras has issues with graphics cards. The manufacturer does not seem to fully understand the issue and insists to use IE it is more optimized (what IE has to do with the streaming over RTSP, I have no clue)
2. There is a joystick controller that connects to the cameras through a LAN cable, the cameras and the joystick are connected through a branch switch. I have to inspect this...but is there a way to know if it is causing any throttling? Without having access to this switch (yet)
What do you think? Is it hardware related (switch) or software (codecs/firmware compatibility) or something else?
Here is a log
