ubuntu 14.04 - GStreamer 1.2.4 with Blackmagic Intensity Pro: Can't grab video in 1080p50, only 720p50 possible -

i hope of can me out.

my setup / configuration:

• amazon firetv, resolution set 1080p50
• 1x2 hdmi splitter / hdfury3
• blackmagic intensity pro pci card
• ubuntu 14.04.1 lts, kernel: 4.2.0-35-generic
• latest blackmagic drivers linux (desktop video 10.6.2)
• gstreamer 1.2.4 including necessary plug-ins bad, ugly etc.

i can grab in 720p50 (fitetv resolution set 720p50) using hdmi-via-splitter or component-via-hdfury3 connection:

gst-launch-1.0 decklinksrc connection=hdmi mode=16 device_number=0 ! xvimagesink sync=false  gst-launch-1.0 decklinksrc connection=component mode=16 device_number=0 ! xvimagesink sync=false 

i fail, however, @ grabbing in 1080p50 (1080p60 doesn't work either). none of decklinksrc supported 1080p/1080i modes working (modes 5-15). behaviour follows:

• modes 13-15: pipeline either aborts error "gst_decklink_src_start: enable video input failed".
• modes 5-12: gstsystemclock initialized, i'm getting perpetual "gst_decklink_src_start: enable video input failed" debug messages while no video pop shown.

here debug results:

i able reproduce issue on different machine using intensity pro card. thoughts?

turns out intensity pro card doesn't support 1080p50 or 1080p60 formats. solution either stick 720p or upgrade intensity pro 4k model.
