MultiCam solutions are using CPU and GPU resources for recording and streaming the program. Hardware is different between the server boxes so you need to take care about limitations for maximum number of streams supported:
Our recommendation for IP-Box:
- 2x GPU, 0x CPU (1 record +1 live stream or 2 live streams with no recording)
Our recommendation for SDI-Box:
- 2x GPU + 1x CPU (1 record + 2 live streams or 3 live streams with no recording)
GPU streams work only when a monitor is connected to the screen output of the system (DP or HDMI interface).
If you use the system with KVM extender or without monitor (RDP, Teamviewer, VNC), MultiCam will use CPU for all streams, and GPU will not be available. CPU will be overloaded and you will have a problem with sound and/or with video inputs.
- Sound “jumps” and interrupts
- Video inputs disappear for 1 second or less
If you open Task Manager, you will see something like this:
- Connect your monitor to HDMI or DP.
- Check the configuration of the record and streaming (remember about our recommendation above)
You should see “GPU encoding” activated in the Live streaming easy setup area.
You should have MP4 H.264 (NVidia GPU) selected in the video codec for PGM recording.
- Open Nvidia Settings (Right Down corner)
- Go to Workstation => View System Topology and find the output with connected monitor
- After click on EDID =>Export => Current output and Export this file to Desktop (for example)
- After click on LOAD tab, open EDID file and choose the same output. For example, for our case, we made export for DVI, and choose DVI when load file.
- After you will see the icon “monitor” and note - “File” opposite output what you choose.
- After you can disconnect the monitor.
