What channel layouts do configurations with channels 9 to 16 use?
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.
you provided the right answer to wm4; I had not understood his question.
Thanks.
@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, no error thrown; every odd channel (1, 3 , 5 ...) is streamed from
the source to the HDMI output (in my case decklink studio 4k which
accepts 8 channel output, I am not aware of any decklink with more than
8 channels out, anyway). The other even channels are thrown out.
As for SDI output, the 16 channels are sent without issues.
(yes, selection of decklink video output connection via ffmpeg options
is still missing).
the output is sent to all interfaces, both sdi and hdmi, at least in my
decklink studio 4K.
