Hi all
Not sure if this is the right location for this post ? Please move it if not.
I'm really hoping someone can help me with this please… I’ve been pulling my hair out for a couple of weeks now !!
I have been running a couple of 24/7 livestreams (streaming to YouTube) for about a year now, they look to the skies for auroras and meteors. I used some cheap tapo 2k 4mp cameras for this. The cameras were dead simple and worked flawlessly, however, the image quality wasn’t great at night (quite noisy) so I recently upgraded to Annke NC800 4k 8mp cameras instead.
The image quality in darkness is much nicer but they have been an absolute pig to setup using the web interface (I gather Annke is the same as Hikvision). Setting up aside (I may come back to that) my biggest problem has been regular pixelated horizontal lines flashing up and if I ramp up the resolution or bitrate this turns into catastrophic screen splitting and vertical bands/green screens etc. Please see the pics.
If I increase the bitrate/resolution this happens...
I was hoping I could use them both at 4K but no chance ! I have dialed them back a bit but tried to keep the image quality as good as possible for the live streams, one is set at 4k to retain best quality and I am downscaling it to 1080p in OBS for streaming, the other is set at 1080p and I am streaming from OBS at 1080p. My current settings are below…. At these lower settings both streams run OK but I still get regular lines/blocky pixels, sometimes every couple of minutes, other times its more stable and then it occurs every hour or so.
So… My internet is OK I think. 200Mbps download and 50Mbps upload consistently. I actually spoke to my ISP last week and they temporarily increased my upload speed to 200Mbps to test it. The higher upload speed made absolutely no difference, as soon as I increased the cameras resolutions and bitrate everything fell apart.
My PC should be up to the job (I think ?) HP Z2 G5 - i7 10700, 32GB ram, Nvidia GTX 1660ti. It is used solely for streaming these cameras.
I have both cameras wired to the PC and Router with Cat6, there is a 1gb powered network switch between the cameras and the PC/Router.
Running it right now the task manager looks like this... Nothing looks under stress. Not sure if those upload zigzag spikes are of any significance ?
I have adjusted all of the camera settings over and over on the Annke web interface and also within OBS to try and remove the problem, basically trying to reduce bitrate wherever I can because I’m not sure what else I can do ?
I am a bit confused. I knew the 4k cameras would be more demanding in terms of bandwidth/encoding etc, I thought my PC and internet speed should handle both 4k cameras fairly easily, but they don’t !
After getting nowhere with settings I started to think perhaps it could be a dodgy cable somewhere so in desperation I’ve swapped out all but 1 cable (waiting for a new one to be delivered on Monday), changing one of the outdoor cables did seem to bring some slight improvement but it certainly hasn’t fixed the problem.
I’m not sure where to look next ? Any advice would be most welcome at this stage. A simple camera upgrade has turned into a bloody nightmare that has dominated a couple of weeks of my life !!
Thanks.
