"Blackmagic DeckLink HD" doesn't detect HD-SDI

PostWed May 09, 2018 2:31 pm

Dear all,

I have issue with "Blackmagic Design DeckLink HD Extreme 3D/3D+" it working fine with SD-SDI, but doesn't not detecting HD-SDI.. I tested on two different HD-SDI source and have the same issue.

obecli> probe input
Probing device: Decklink card 0. Timeout 20 seconds
.[decklink] No valid frames received - check input format
.Could not probe device

Also i tried set input formats, like:
obecli> set input opts video-format=pal
obecli> set input opts video-format=720p50

    Open Broadcast Encoder command line interface.

    obecli> set input decklink
    obecli> probe input

    When i give HD-SDI:
    [root@obe1 ~]# obecli

    Open Broadcast Encoder command line interface.
