Troubleshooting a vMix Call

Try downloading the latest version of vMix 17 from the main thread as there have been a couple of updates recently. What sort of computer is it, and is Windows and drivers all up to date etc? I understand, however all I can go on is the error message Windows is telling the vMix Desktop Capture app, so not much I can do to fix it until you are able to figure out what might be using up CPU on the system and in particular the audio. Update, I have soughted the problem out, it's nothing to do with audio errors at all and I don't know why this would make any difference as I am the administrator of my Laptop.

I decided to run vMixDesktopNDI as Administrator and hey presto it worked, I can know change the audio, frame rate and show cursor boxes.

Live Production Software Forums www. Welcome Guest! Troubleshooting weird Behaviour in vMix Call. They were using skype like products with poor results.

For the sake of testing, one year ago I've made a pre event dryrun with this setup 1 Main Deck hosting the vMix Calls at our HQ where a conference room with 30 seats was listening and 2 people were having a speech 8 joining vMix Call from hotels all around Italy, Sardinia and Sicily included where a conference room with 30 seats was listening and 1 people was having a speech Except for a hardware failure in one of the 8 places BSOD and a problem with audio that being listened through loudspeaker had a delay and was feeding back the test was quite successful so I further developed the project.

How much latency affects the streaming even having more than 10Mbits available? How can I pre check a location to be sure to not having problems on the day of the event?

Regards Marco. Marco, With that many guests, your bandwidth requirements go up quite sharply. You would be better off using a video conference service instead of vMix Call.

The VC service is designed for real-time, bi-directional engagement. Audio sync should be perfect all the time.

Consider as an example the weekly World of Live Streaming show that uses Zoom. Quote: How vMixcall traffic is routed?

Hi mjgraves Thanks for your answer Quote: With that many guests, your bandwidth requirements go up quite sharply. Hi Marco were the Sicily and Sardinia locations affected by your issues? If these 2 locations are those you had problems with, I'd bet it's due to their geography and ISP infrastructure being less good as on the continent Regarding vMixCall and WebRTC, I also quite frequently use vMix for connecting several places together during live events productions.

Most of the time it remains in France up to 8 cities but from time to time I also have to deal with foreign countries all over the planet. So far I must say vMix Call does the job very well. I had issues btw, most of the time due to bad network environnement despite I always provide a setup roadmap and requirements - some people just don't care and use Wifi or shitty network gear and lazyness or incompetence of the remote crew, so I understand.

Twice I also experienced very bad transmissions, each time remote location was a small island in Asia, once they even tried to use a hotel broadband satellite link.

Obviously I had to cancel their participation 'cos even audio was unusable. In general I can say that up to ms latency is not an issue at all.

However the internet is not equal everywhere in terms of quality and routing. I use vMix with video conference services every day. They can be complementary. So maybe the remote station had the issue? Hi everybody Finally I got all my stuff back in my lab and I've been able to troubleshoot the problem. Launched the first with same preset that had no problem and was continuing to work perfectly 2. Launched the second with same preset that video delay problem and was continuing to have delay problem 3.

Checked vMix Call Buffer on the second and it was increasing over and over 4. Copied the preset from the first to the second and the problem disappeared 5.

Launched again the second as in step 2 but changing the vMix Call pointing to another one Hosted on the main vMix. Again video delay 6. Launched again the second as in step 4 but changing the vMix Call pointing to the same having problem.Check to make sure the caller has a Webcam and Microphone plugged in and these have been selected in the browser.

In Google Chrome the camera and microphone can be configured by clicking the grey Camera icon at the top right hand corner of the address bar. In FireFox, the browser will prompt to select the camera and microphone each time the call is connected. This may occur if the internet connection is interrupted. This indicates network congestion between vMix and the caller.

The video and audio from the caller will adapt automatically after several seconds, however if the Return Video bandwidth is too high for the callers. Audio quality may also briefly drop to Telephone quality during periods of network congestion. If network congestion can be ruled out, try a different webcam.

During periods of network congestion, the received frame rate may drop as low as 1 frame per second. The video frame rate may also lower in response to camera lighting or performance limits of the caller's laptop, PC or mobile device.

This latency can range from approx ms for guests on the same or nearby network to between 1 and 1. As vMix Call will generally adapt to the worst case scenario, if a brief period of network congestion results in higher than expected latency during a call, the guest can refresh their browser. If speakers must be used such as in a boardroom environmentthe Microphone will need to be directional to ensure it is not picking up the speakers audio.

The video and audio from the caller will adapt automatically after several seconds, however if the Return Video bandwidth is too high for the callers internet connection, then you may need to select a lower quality by right clicking the Call input in vMix.

High Latency vMix Call uses what is known as a Jitter Buffer which adds a variable amount of latency to each call to ensure smooth video and synchronised audio. As vMix Call will generally adapt to the worst case scenario, if a brief period of network congestion results in higher than expected latency during a call, the guest can refresh their browser to re-establish the call and reset the Jitter Buffer.A number of bundled pieces of software with laptops and PCs has been found to interfere with the graphics card and cause problems with programs like vMix.

Have been using Zoom. Today was the second week in a row that I have tried with vMix and at the last second as to revert to zoom to do it due to issues with vMix call. The issue today was a delay in video; video freezing and poor audio quality with one guest the other guest was fine - I played with settings and could not sort.

At the last second we shut down vMix and went to Zoom and the video and audio from that guest was fine so I assume that means the problem was not on her end Not sure where to start troubleshooting this Most built-in webcams can only support p Zoom is itself a webrtc-based service.

Hi I have been using the beta I upgraded to the release version. It seems to be related to audio. I have a background mp3 file playing during the stream and after about 5 minutes the audio starts to stutter badly. Eventually, I get a Windows message to tell me that vMix has crashed.

If I click on the Windows message to close it, the whole app closes down. I have reverted to beta version. This leads me to believe it is a minor change in the release version which has caused my issue.

Is it just me??!! Any ideas appreciated. I have uninstalled and reinstalled from scratch to no avail. AfjalKhan Did you try the final release of vMix You cannot post new topics in this forum.
