I want to use decklink to output SDI input to SDI

[Yusuke]

I want to use decklink to output SDI input to SDI.

This is OK.
gst-launch-1.0 \
decklinkvideosrc device-number=0 connection=sdi mode=1080i5994 profile=4 ! \
decklinkvideosink device-number=7 mode=1080i5994 profile=4 sync=false \
decklinkaudiosrc device-number=0 channels=16 ! audio/x-raw ,format=S32LE !
decklinkaudiosink device-number=7

This is NG.
gst-launch-1.0 \
decklinkvideosrc device-number=0 connection=sdi mode=1080i5994 profile=4 ! \
decklinkvideosink device-number=7 mode=1080i5994 profile=4 sync=false \
decklinkaudiosrc device-number=0 channels=16 ! audio/x-raw ,format=S32LE !
audiomixer ! decklinkaudiosink device-number=7


How can I use "audio mixer" to output SDI?

I am Japanese.
Sorry for the poor English.
Thank you.

Perhaps you want to allow some latency on audiomixer ? (see audiomixer latency
property in gst-inspect-1.0).
