Processing VBI data in macOS

Hi guys! I develop a driver that intends for digitize an analog video (include sound and VBI data such as teletext and closed captions). Can you help me? I want to output teletext in VLC, but I don't know what I should use for this: for output video stream I use IOVideoDevice, for example, but what is should I use for creation a VBI streams? If it is possible, can you tell me about processing VBI data by VLC?

Details: output video is a bytes stream that not linked to any video formats (like as MPEG)

P.S. Sorry for my English

It's quite tricky, IIRC, because vbi is managed by the TS demuxer, the decoders and the zvbi module.

I don't think there is a common interface for that on macOS. Not even sure the AVCapture can output a full TS...

Come on IRC, when you have your first driver set.
