Hello! I have an HD-SDI stream of TV channel with multiple audio tracks (languages) that come to Decklink capture card via SDI cable. Video and all of the audio tracks are determinded by the capture card. I need to create 5 separate RTMP/HLS streams each on with its own audio track (language) or create single Mpeg2-ts stream with one video and all 5 audio tracks (languages).
We have an article on how to configure alternative audio tracks for HLS delivery from an MPEG-TS encoder.
