I’m able to successfully connect two remote vMix systems or iOS (Larix Broadcaster) via SRT. However, I need to get a stream from a musician into vMix with high quality audio and cannot figure out a method to get from his macOS over the Internet into vMix. We’ve tried vmix call but the audio is only streaming at 65kbps and it sounds pretty bad.

I tried setting him up with OBS 25, but it seems like they do not support SRT on MacOS yet - or Atleast the version of ffmpeg they include doesn’t. I tried having him install the home brew ffmpeg with srt but couldn’t get that to work in OBS. I tried streaming his webcam via VLC, which didn’t work either.

Does anyone have a free or low cost option for a direct connection from macOS to vMix? The quality of the feeds I have been able to get working using SRT via iOS or PC are really incredible.

I'm hoping OBS makes the changes required to their macOS version of ffmpeg soon, which would make it pretty easy. According to an OBS developer on 4/4, they said they would be updating it soon. https://obsproject.com/mantis/view.php?id=1619 I have not been able to find any other solutions, but I will let you know if I do.

Did you do anything to get SRT enabled in ffmpeg or just out of the box installation?

I can confirm this is working now in the latest version of OBS for macOS. Video looks good and audio sounds great, using SRT in both directions with OBS on a mac over the internet. They are sending me high quality video and audio and I am returning my output to them at a low bit rate so they can see what I'm streaming and hear me. They put OBS into studio mode so they can see what they are sending me and what I am sending them at the same time.

Using srt://ipaddress:port?latency=200&pbkeylen=32 and default settings in vMix. vMix is setup for both connections as listener and I setup UDP port forwarding on my router for those two ports.

Works great - thanks for the help.

You had the two musicians playing together somehow? This doesn't seem possible to me. We didn't have any issues with studio mode, they were able to see my feed without issue.

Hello,

Very interesting !
if I understand correctly, you receive the sound via soudjack.eu (great sound, very low latency ?) and you receive the webcams via SRT? And you sync video and audio into vmix ?

I have some troubles with latency on OBS, i nerver have less of 2 seconds. Maybe i made a mistake in the output of vmix for return video. Vmix has to be on listener on input and output ? Do you use the rendez-vous ?

Thanks
