Edited out too much repeating information. I suspect I made some sort of encoder setting error. This led to a compounding lag where my IP cam sources where getting slow and choppy. Initial testing showed the less I did otherwise with the PC the better. I had been gaming and streaming in and out with no issues a few weeks prior. Initial trouble shooting revealed the encoder was reporting only 35% usage with one cam and I still got this symptom.
I eventually wiped my drive and installed from scratch. I am not messing with the stream intake/encoder settings other than bitrate and resolution. So far the cams seem smooth and on pace with displayed PC time stamp. There is a bit of back and forth 3-5 second with the PC. The clock display is a loaded html file which itself is about 30 seconds behind the PC.
I ran a 7 hour stream today @ 720 at 1024 bit rate… 2 720/1024br RSTP cam source. finished with same 4 second “delay” it started with.
Overnight and tomorrow I am bumping everything up to 1080dpi 4096br. I expect there will be some issues and that is fine at this “extreme” for the system.
I will be using the PC a bit at the same time nothing too heavy until tomorrow night.
I am running: AMD Ryzen 5 1400 Quad-Core @3.20 GHz Gigabyte B450M DS3H - 8GB DDR4- Windows 10 20H2 19042.870 on a 1TB partition on a 2TB NVMe - NVIDIA GTX1070
Maybe the Ryzen 5 is just a little too close on the spec side?
The point is… SOMETHING changed. I will report back regardless of what I find.
