Hey, Nikita. I've just scanned the code, starting to understand it. Looks very good, just jotted a few comments as I went...

This needs to be configurable by the user as well, I think?

Yes. Made validate_receiver_resources() a configurable callback.

Similarly to https://github.com/sony/nmos-cpp/pull/271/files#r1028471346, I wonder if we want a make_streamcompatibility_receiver_validator function that takes the SDP parser and validator to prevent the user having to write this whole function.

Added make_streamcompatibility_receiver_validator that takes nmos::transport_file_parser and it has some restrictions:
- this function is expected to parse and validate the transport file at once. Not sure if it can be split into two arguments because I can't imagine a validator that is unaware of the internal details of the transport file format.
- functions of this type take
gatebutparse_rtp_transport_file(the only function of this type?) doesn't actually use it.

Hmm, yeah, I guess that seemed like a good idea at the time... 5bc3962 😄
We don't like making incompatible changes if we can help it, but if the gate parameter is causing problems, we should revisit.

OK, I'll review to understand what you mean!
…move Flow Compatibility API helper functions into details namespace
…raint Set is a subset of another one

Shouldn't 500 be returned if active_constraints_handler is null?

Shouldn't active_constraints_handler be checked for null before use? If it is null, should it return 500?

I don't think the active_constraints_handler is actually required for the Reset the Active Constraints, just set_active_constraints of the resource to reset its intersection_of_caps_and_constraints and the endpoint_active_constraints.

Hi, we would love to see IS-11 support in NVNMOS. Thanks, 7thSense team! |

Hi @N-Nagorny, I hope you are doing well. We are now looking into this PR. I just merged it locally to master, but when I try to push to your repository, I am getting a permission denied error. Can you add me in as a collaborator to your nmos-cpp repository. So I can complete the review and make any necessary changes. Many thanks. |

Hello everyone!
This PR adds Stream Compatibility Management API (AMWA-TV/is-11@e98d156) implementation and IS-11 support.
Could you please review it and describe what's needed to change to be merged?
