Hi.

Need to send a UDP multicast stream using FFMPEG.

I realize at this point this cannot be done in Vmix, but is anyone doing this my using the external output directly into another instance of FFMPEG and could you share?

I think you can send UDP over VLC with vMix
There are some instructions on internet

You can do it like this:

On vMix PC:
- Enable External Output in vMix
- ffmpeg.exe -f dshow -i video="vMix Video":audio="vMix Audio" -b:v 1500k -f mpegts udp://remoteip:1234

For 'remoteip' put in a multicast IP address.

Regards,
Patrick

So vMix can actually send udp?
Do you have some video tutorial for this?

No, vMix cannot send a udp stream nativly.

But: vMix can send the output to external vMix Audio/Video direct show device. And from there ffmpeg can grab the video and send it by udp.

No, there isn't a video tutorial abut this.

Just try:
-Activate external output
-Download ffmpeg and open command prompt. Put in command with a vaild IP
-Open VLC to play the video

Do you also know a good way to play the multicast stream to a browser without using plugins?

No, I don't know a way without plugins. None of the current browsers is capable to receive multicast streams natively. Perhaps this will change in future...
