ATEM Mini (Extreme) streaming to Vimeo, Rumble and Bitchute

Can the ATEM Mini Pro and Extreme (inc ISO versions) stream directly to Vimeo, Rumble or Bitchute as an alternative to YouTube? If not, are there any plans to support these as they are rapidly becoming very popular?

Have you tried modifying the xml file as mentioned in this post?

This is what mine has for twitch

<LiveStream serviceName="Twitch" url="rtmp://live.twitch.tv/app" key="live_7secret stuff here" lowLatency="False">
<Credentials username="" password=""/>
<bitrate low="4500000" high="6000000"/>
<audioBitrate low="128000" high="128000"/>
</LiveStream>

I am looking into getting a streaming device of some sort and Rumble as an option would be great. Please let me know if you intend on adding support for these other streaming platforms.

I was able to live stream to Rumble from an ATEM Mini Extreme ISO, but it is awkward to set up.

Evey time you start a live stream on Rumble, not only do you get a new stream key, you also get a new URL for the stream destination server. That means that you have to edit an xml file and upload it to your ATEM using "Load Stream Settings" every time you do a live stream on Rumble.
