Using Decklink Quad HDMI Rec with Multiple Applications

PostSat Mar 25, 2023 11:37 pm

MAC OSX OS X 13.2.1
OWC Mercury Helios 3S
Link Width 4x
Link Speed 8 GT/s

Several applications don't seem to work with the Decklink Quad simultaneously. All video feeds appear to be in good shape, for instance, if I have Ecamm running then I try to choose a camera on Zoom, the video source indicates that it is not available. Same for Facetime and Quicktime, and this is the same behaviour in reverse.

Is the driver or the hardware itself limited in some way? This is difficult for me to believe when a $100 Camlink 4K can be used with multiple applications at once.

Thanks

Neil.
