The monitoring can be used various purposes, for example custom tally devices. This is a very simple protocol, a bit verbose perhaps, but still very easy to use for both routing inputs to outputs but also for monitoring changes in the routing. The basic input to output routing can be changed and monitored using the videohub routing protocol on port 9990. It is also very easy to switch or monitor inputs, so for example you could use something like a networked Arduino, ESP32 or similar MCU to access the switcher in various ways (Say Tally display, input switching according to some sensor, go wild!) Videohub Routing protocol For example you can easily start a video stream to a custom RTMP endpoint, something you actually can't do from the proprietary software without editing the Streaming settings XML file. Always make sure your switcher(s) are on a private trusted network!Īlthough these protocols are somewhat limited in functionality, they do provide the basics for switching of inputs/outputs, monitoring of inputs/outputs, recording and also streaming. Note: All of these protocols, even the UDP one, are open without any kind of authentication. FTP is also available on the models that include recording, these are the Pro and Pro ISO models.
Blackmagic ATEM Ethernet Protocol 1.0 on port 9993.Videhub routing protocol on port 9990 ….The protocols available are the following: For some of these you might even find ready made libraries for easy access. These can all be accessed manually for example using telnet or easily from programs. Fortunately it has been reverse engineered and there are plenty of various libraries (C++/Qt, C#, Arduino, etc) available so custom applications are possible.įortunately the ATEM Mini video mixer devices can also be accessed with a couple of simple TCP protocols too. And the UDP protocol is closed and undocumented officially.
Unfortunately that piece of software is available for Windows and Mac OS only, strange enough as it is also made with Qt, so a Linux build should be a walk in the park. There is the official Blackmagic Design proprietary Windows/Mac OS only ATEM Switcher software and that uses the proprietary, undocumented, UDP protocol that is used to do just about everything possible on the various video switchers. The ATEM Mini switches can be manipulated any many different ways.
