Our last successful event was March 21, 2020, using 23.0.0.46. (https://www.youtube.com/watch?v=jVfZqHtbW10)

I also demoed my preset successfully on Saturday, March 28, 2020.

I updated to 23.0.0.49 on March 30, 2020, then to 23.0.0.50 on April 2, 2020 (the morning of this evening Tech Check).

In the tech check, I had:

• one user in Camden SC, USA with "normal" connection: decent AV, avg latency, no issues. I did not get his Speed-Test results.
  
• three users in the same community with nearly a full minute from my "Can you hear me" to their "Yes".
  
• those 3 users shares a 250MbpsD/30MbpsU connection through TruVista, according to Speed Test at the time of the event
  
• one user in Cincinnati OH, USA, also with nearly a full minute from my "Can you hear me" to their "Yes".
  
• the OH user has a 500/50 connection, according to Speed Test at the time of the event
  
• audio for the 4 affected users was very choppy

I had one caller rejoin twice, then I closed down vMix, restarted, and had them all rejoin, and the result was the same. I then had all join a Zoom meeting and video was clear, audio 5*5.

I released everyone, reopened vMix and submitted a support request, then used the vMix site Contact form to request support, providing my serial as well the 5 vMixCall Keys used.

Please let me know if others are experiencing the same. I'd have an easier time attributing it to regional bandwidth if I didn't have those two anomalies: one bad in OH, and one good in SC among 3 other bads. I'd have an easier time attributing it to a bad update if I didn't have the one good caller in SC. I don't know where to go with this.

Also, it would be helpful to have the vMixCall server's TURN URI to feed to https://test.webrtc.org/ for testing purposes.

My live event is scheduled for Tuesday. I'll be troubleshooting to the extent that I'm able through the weekend and performing another Tech Check Monday afternoon.

Thank you,

Chad

Hi Chad,

vMix itself has very small buffers in the sub-second range, this is also the case with most browsers, and our servers.

So a very long delay well above this usually indicates the caller is on a congested 3G/4G/5G connection either directly on the phone or via tethering,
can you confirm if this was the case for the callers experiencing issues?

Regards,

Martin

Martin,

I just re-tested with only one of the callers from last night and we had clean AV. If you guys don't see anything in your logs related to the Keys I submitted about 20 hours ago, I'll hold out for Monday evening's Tech Check, drop to 720p just in case, and pray for a smooth show Tuesday. Wish us luck, sir.

Best,

Chad
