I use IIS publishing point to deliver live video stream, also I useHLS (IOS devices) stream format (url example: http://xxx.isml/manifest(format=m3u8-aapl).m3u8) and it works well. But when i put closed captions stream to usual .isml stream this CC stream doesn`t appear in HLS stream. It seems that IIS HLS transformation loses text stream (CEA-608 in HLS stream).
I use Expression Encoder SDK to stream video and to put text into this live stream. So the question is - Does IIS support HLS closed captions (CEA-608) transformation?
