Testing on a decklink Mini monitor card. 02:00.0 Multimedia video controller: Blackmagic Design DeckLink Mini Monitor Subsystem: Blackmagic Design DeckLink Mini Monitor Capabilities: [40] Power Management version 3 Capabilities: [48] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [58] Express Endpoint, MSI 00 Kernel driver in use: blackmagic_driver Most modes work. However modes 14, 15, 16: (14): HD1080 50p - 1080p50 (15): HD1080 59.94p - 1080p5994 (16): HD1080 60p - 1080p60 do not work.

I am not sure if it's a wrong setting on gstreamer side or a driver issue. I haven't found documentation for the 1002 error code yet. Tested on master repos from 5/5/2015

Can you use those modes with the Decklink applications that are provided with the SDK? That sounds like your card or the configuration of the card does not support them.
I rechecked specs of Mini Monitor card https://www.blackmagicdesign.com/products/decklink/techspecs/W-DLK-05 and it looks like 1080p50, 1080p59.94, 1080p60 are actually not supported on this card. Other models support them. Let's close issue for now. I 'll try to test on different cards in the future, if problem appears there i will reopen. Sorry for the noise.
