There is no concept like stream or track in SDI. It just has 16 mono
channels without any semantics which are arbitrarily mapped to whatever
you need to transport.


@pkv.stream: HDMI 1.x does only support up to 8 channels (7.1), which
might be the reason for the missing 16. Did you test what happens when
16 audio channels are requested for HDMI out?

(yes, selection of decklink video output connection via ffmpeg options
is still missing).
