UE 5.3 - sending Ancillary Data with decklink plugin

Hello

Does the decklink plugin allow to send ancillary data?

Unfortunately I have not found anything on this, also nit in the documentation. The deckling SDK would certainly support this.

Our receiving end is a pc with unity running which supports receiving of ancillary data.

Anyone has an idea how to start developing this? Is it even possible to extend the current decklink plugin?

Thank you very much
