4K Video outputs with Decklink 8K Pro

[Sidon]

I couldn’t find it back then with the forum search but apparently someone else had the same issue:

Decklink 8K Pro - Failed to schedule fill video

It is because Decklink 8k Pro only support YUV format (8 or 10 bits) when 1 connector is assigned to each of the 4 outputs and mode is 2160p5000. CasparCG sends video using BGRA format to Decklink . So to send video in this configuration, CasparCG Decklink consumer has to be modified.

In the last post they seem to give the reason behind this behaviour, it comes to the server it would seem.
