Guten Tag videofan. Super, dass man nun mit dem VLC-Player auf eine Decklink-Karte zugreifen kann. Aber was ist mit einer

oder
https://www.blackmagicdesign.com/de/products/decklink/techspecs/W-DLK-30
die mehrere SDI-Ausgänge haben? Kann man diese einzel ansteuern? Genau so etwas suche ich. Ich habe 12 Videostreams, die einfangen möchte und jeder Stream soll mit einem SDI-Ausgang auf einem ATEM-Switcher landen.

That's an interesting question.

I don't have any of these multi-input cards so I cannot test it.
I have "only" single-input Intensity Pro 4K and Intensity Shuttle. Each of these has multiple sources (HDMI, YUV, S-Video) but only one input at the time is possible.

If/how will VLC DeckLink Input plugin detect multiple inputs on single Decklink card ? - I don't know.
But you can try it and report back here ;)

Hi, I wanted to thank you for creating the plugin. It works great except for framerates higher than 25p. The image is played back at what appears to be half of the source frame rate. I've tested my card with Resolve and Shotcut and they are able to playback UHD at 30fps and HD at 60fps without any issues whereas VLC doesn't do it. I was wondering if anyone else had this problem or if there is a fix.

Card I use: decklink 4K sdi
