Deltacast has at least one output card DELTA-ip-ST2110 01 - Deltacast and an input version DELTA-ip-ST2110 10 - Deltacast. SuperFly owns a pair of these, which are currently in my possession. But Im not sure if I have the time to commit to anything right now.
Bluefish looks to have some new cards under ‘coming soon’ that support ST-2110 also. It will probably require some changes in casparcg to support, but will probably be easier than a new manufacturer once the cards are available.
One big hurdle to supporting new cards is that the licensing of the SDK is often incompatible with CasparCG. As in, the source code of the SDK cannot be shared publicly, and so any builds containing the SDK will not be publicly sharable without violating the GPL license of CasparCG.
I dont think this should block this from being prototyped at least, as I think there will be ways we can work around this limitation
@didikunz If AJA would release a ST-2110 card that would be ideal. They recently open sourced their SDK https://github.com/aja-video/ntv2, and so is an easy candidate for supporting. This is on my list of things to play around with if I can find time
