A module to control Blackmagic Design ATEM Switchers
If setInterval
send atem.changeTransitionPosition(num)
quickly like 15ms
after a few minutes, The ATEM dead.
If change transition position by hand on the blackmagic's Broadcast Panel
, the interval is faster than 15ms, but The ATEM is fine.
I don't test other command have same issue.
I'm using this library, and it is working great except for one thing. If I lose connection to the switcher, my script just hangs. There is no error, and no attempt to re-connect. Am I missing something simple here? Thank you.
The code should be updated to allow control of multiple M/E for larger ATEM switchers.
I'm running into issues using this library in my project. When I call prototype functions like autoTransitions() from a callback where this
is not the original ATEM object I get errors. Might be something having to do with CoffeeScript. It's making this library unusable in my project because I can't call prototype methods from outside the ATEM class context.
module.exports = function(otherThing){
var ATEM = require('applest-atem');
var atem = new ATEM();
atem.on('connect', function() {
setInterval(function() {
atem.autoTransition(); //THIS WORKS
}, 1000)
});
otherThing.on('someEvent',function(){
atem.autoTransition(); //DOES NOT WORK
});
return atem;
}
The connection to the ATEM Mini Pro is working fine. Changing inputs etc works as expected but when I try to use the uploadFromPNGFile method, it doesn't seem to be working.
When I manually add an image in the media pool and run the code, it only removes the image I manually uploaded but the one I uploaded with code does not appear.
Path is correct and I'm not getting any errors.
Running macros and watching the net traffic with WireShark.
using:
connect('192.168.0.6')
runMacro(0)
Works but traffic continues from the NodeJS client to/from the host and after a while the vendor provided UI stops working. How to "disconnect" from the host and stop the net traffic?
how Upstreamkeys works?
atem.changeUpstreamKeyState(1, 3);
It would be nice if the plugin implemented all of the features of the ATEM protocol. Most of them are listed here: http://skaarhoj.com/fileadmin/BMDPROTOCOL.html
i got sh: build: command not found
error at postinstall
stage when i run npm i applest-atem
macOS and Raspbian both
I see that every time a connection is attempted a new udp socket is created. Should this be the case? Shouldn't the hello command just be sent out again only?
Also, I don't believe it's necessary do a manual bind since node auto-binds to a random port when you send out your first packets.
I am using the actual version of this library. If I change e.g. the input of the programbus then the statechanged event seems to execute several times. It would be good to have the statechanged event execute only once.
Thankyou
