SRT Initial Connection with vMix from iPhone

[hanfordtroy]

We are using your great kit to enable live SRT AV streaming from an iphone to a live vMix session. It has worked very well thus far. We have one odd observation. When we start publishing, we see packets moving, and we see the SRT connection is established, immediately. Oddly though, we don't end up seeing or hearing video for about 90 seconds on the receive side. Its just black screen in our preview on vMix. And, then we see the video, but it seems to be in fast-forward-mode for 2-4 seconds, then the video is live, and a perfect solid stream. This could be an issue on the vMix side for sure. I don't think it is bandwidth related, bc the stream plays fine after about a 90 seconds. Anyway, wanted to share my experience. I am happy to help figure this out, if you'd like. Nice Work!

Is vMix the name of a service? https://www.vmix.com/
Since I'm not familiar with the specifics of the service, it would be best to ask vMix for the reasons behind this issue.

I have tested connections using Ffmpeg, SRT, and Cloudflare but have not encountered such phenomena.
Thank you for your report.
