Decoding is not keeping up

[glue]

Hello folks, I'm a newbee to ZM and just setting up my first network video manager with ZM v1.36.32.

My ZM is running as a VM with 16 GB RAM and 8 Cores on a Proxmox Cluster, so there should be enough power to rely on.

I added my first camera, a Reolink RLC-842A, which worked well using this howto on reddit: https://www.reddit.com/r/reolinkcam/com ... inder_nvr/

I added a sub monitor with 25 FPS and 640x360 using the RTMP stream (1):
- rtmp://IP/bcs/channel0_sub.bcs?channel=0&stream=0&user=admin&password=PASSWD
- Mocord
- TCP
- Camera Passthrough

Then i added a main monitor with 10 FPS and 4K Resolution with RTSP stream, as I could not get the RTMP stream to connect (2):
- rtsp://admin:PASSWD@10.50.10.100:554//h264Preview_01_main
- Nodect
- TCP
- Camera Passthrough
- Connected Monitor: sub from above

The monitors connect and work.

After a short period of time I get this log messsages:

1/7/23, 2:02:25 PM GMT+1 zmc_m2 1246 WAR Decoding is not keeping up. We are 640 seconds behind capture. zm_monitor.cpp 2624

I tried to double CPU cores and RAM, disabled save JPEGs storage option for sub monitor and reduced the FPS for sub (4) and main (8), but I still have the same problems:

1/7/23, 3:31:44 PM GMT+1 zmc_m2 2188 WAR Decoding is not keeping up. We are 233 seconds behind capture. zm_monitor.cpp 2624
1/7/23, 3:31:44 PM GMT+1 zmc_m2 2188 WAR Decoding is not keeping up. We are 234 seconds behind capture. zm_monitor.cpp 2624
1/7/23, 3:31:43 PM GMT+1 zmc_m2 2188 WAR Decoding is not keeping up. We are 233 seconds behind capture. zm_monitor.cpp 2624

Do you have any ideas who to solve this?

Hello,

sorry for bumping this thread. I still have no clue where to look at. I'd be glad for any hint.

Thanks!

You don't have enough cpu to decode the 4k stream.

reduce fps, turn off saving jpegs, etc...

I had the same problem with a RLC-823A. It started throwing the same not keeping up errors after the last upgrade. I rebooted the camera and things have been stable for a week now. I'm running on Proxmox, 12 vCPU and 32 Gb mem.

My HD stream is nodect and linked: 3840x2160, 8 FPS, 4096 Kbps max and Interframe 1x
My SD stream is mocord: 640x360, 7 FPS, 256 Kbps and Interframe 1x
