Webcaptioner added support for vMix and seems to be a great option for those looking to have closed captioning done on the fly, without using YouTube or Facebook’s built-in feature, which is not very impressive according to our viewers.
Hi @PIBCaguas! Thanks for using mimoLive and thanks for the feature request. Close Captioning is a future topic. Meanwhile, integrating WebCaptioner should be possible with mimoLive using the technique used for integrating with OBS: https://webcaptioner.com/help/integrations/add-captions-in-obs/
TL;DR: You can use a Screen Capture source to capture the output of WebCaptioner.
