Hello

Does anyone have experience with streaming via UDP over the public Internet?

We want to stream a camera signal (720p, live output) from the encoder (vMix Basic) from the event directly
into our studio 120km away with a maximum delay of 1 second. In the studio we want to insert the stream
with vMix (Stream Input).So we do not want to stream through a cloud, but directly from event to studio.

Can someone tell us which software and hardware are needed?

Could vmixCall a solution?

Best regards
Patrick

Consider that literally every enterprise class video conferencing system passes video+audio over UDP and the public internet. Also, most VoIP phone systems send the media over UDP and the public internet. SIP is the most common protocol for signalling, with RTP or SRTP for media.

The reason that vidconf and VoIP is significant is they are fundamentally real-time communications, that can be peer-to-peer connections. Minimal latency.

TCP was avoided as media transport for many years because staying real-time is more important than a few lost packets. TCP didn't start to be used for VC/VoIP until Microsoft introduced their Internet Communication Server/Lync product. As is their way, they had to change things to skirt existing standard operating procedures. Embrace and extend, etc.

vMix Call most certainly works for this. It's a WebRTC solution, which is essentially a technology developed for delivering video conferencing via the web browser. It has built-in solutions for NAT traversal, supporting direct peer-to-peer connection when possible. This minimizes latency.

I'm not familiar with things like MediaLook, but they are certainly an alternative that might support higher bitrates. Also RTMP MiniServer.

Yes I use HDMI and SDI encoders I purchase on eBay to send video over the internet. Delay is less than 1 second.

On vMix you receive it with the VLC stream input

You could do the same thing computer to computer using VLC to stream and vMix to receive

I would recommend one of the following
- vMix call (WebRTC)
- Medialooks (SRT with error correction)
- Zixi (UDP with error correction)

VMIX call is a valuable option, especially because of the return video.
i added a small manual how to use.
VMIX Video Duplex
