Question about scanning capture card #11

Hi,

I have two instances with DeckLink Mini Recorder 4K. I'm using Blackmagic_Desktop_Video_Linux version 11.1 with SDK version 10.9.10.

On one device I have the following output:


        Browse there for Pictures of the captured Material

+-------------------------------------------------------------------------------------------------------------------------------------------+
| #             | Device Name                   | Can Input & Detect | Signal Detected | Active Connection | Detected Mode  | Pixel Format  |
+-------------------------------------------------------------------------------------------------------------------------------------------+
| 0             | DeckLink Mini Recorder 4K     | Yes                | Yes             | HDMI              | 1080p59.94 RGB | Big-endian RG |
+-------------------------------------------------------------------------------------------------------------------------------------------+

The other one has got this:


        Browse there for Pictures of the captured Material

+-------------------------------------------------------------------------------------------------------------------------------------------+
| #             | Device Name                   | Can Input & Detect | Signal Detected | Active Connection | Detected Mode  | Pixel Format  |
+-------------------------------------------------------------------------------------------------------------------------------------------+
| 0             | DeckLink Mini Recorder 4K     | Yes                | No              | HDMI              |                |               |
+-------------------------------------------------------------------------------------------------------------------------------------------+

What would be wrong with my setup? Both hardware instances are the same, Blackmagic driver and SDK are also the same.

Any help would be very valuable.

Thanks

Does the 2nd one segfault at some point by any chance? We just fixed a bug where the mode was not detected on the first run, and the debugger crashed. This is going to be included with the update to SDK 12.1
