It’s working in server 2.0.7, but’ it’s also old…

what is MVCP? Thats not something I’ve heard of before. Did you mean AMCP?

That log output says the problem, it doesn’t know what MVCP is either

@robeartotv has earlier wrote about it.
LOOPING with constrained MVCP protocol - General - CasparCG Community Forum (casparcgforum.org)

It’s not AMCP I mean, it’s a protocol for f.eks. Viz Mosart automation.

Interestingly, if I look in the code for 2.0.7 there is no reference to ‘mvcp’.
And if I try and find the source for the build they used 2.0.7.34150ef, the git hash at the end of it does not appear to exist either.

Vizrt used to ship a version of casparcg with mosart (Controlling CasparCG from a Vizrt Mosart? - #3 by eskojua), perhaps that was a custom version with a custom implementation of mvcp that was never contributed back upstream?

Either way, they don’t do that anymore, and it doesn’t exist in any official builds anymore (if ever)
