We have been using Vmix call for the last 3 months with just some minor bumps until last night.

1 of 4 guests had excessive video latency (+/- 2500ms) while the audio latency was normal (+/- 300ms). Overall bandwidth was around 2mbs. This is a frequent caller that we haven't had many issues with - same computer, same location, etc. We had the caller refresh the Vmix call window and it corrected but nearly immediately started building back up. We then had the caller fully reboot their computer and after they came back the issue persisted. Toward the end of the show the video latency suddenly cleared up with no apparent cause.

The caller also reported issues connecting on vmixcall, taking multiple tries to establish.

I have read about the Jitter Buffer but I am not clear on if a high jitter buffer can cause video ONLY latency like we experienced or if that would present with both audio and video with high latency.

Thank you!

1) Are you referring to the CPU that is running Vmix or the CPU that is running Vmix Call?
2) All of the calls are setup for direct P2P only and this caller was using the same computer, internet connection, etc. as always.

I am very interested to know if the Jitter Buffer affects video and audio separately because if so that seems to be the likely cause. And again, if that is the case, are there any troubleshooting steps that we can take on the remote end that mitigate that.
