IntensityPro: can't grab in 1080p using GStreamer 1.2.4

Hi guys,

I hope some of you can help me out.

My setup / configuration:

• Amazon FireTV, resolution set to 1080p50
• 1x2 HDMI splitter / HDFury3
• Blackmagic Intensity Pro PCI card
• Ubuntu 14.04.1 LTS, kernel: 4.2.0-35-generic
• Latest Blackmagic drivers for Linux (Desktop Video 10.6.2)
• GStreamer 1.2.4 including all the necessary plug-ins like bad, ugly etc.

I can successfully grab in 720p50 using HDMI-via-Splitter or Component-via-HDFury3:

Code: Select all

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, at grabbing in 1080p50 (1080p60 doesn't work either). None of the decklinksrc supported 1080p/1080i modes are working (modes 5-15). The behaviour is as follows:

• Modes 13-15: The pipeline either aborts with an error "gst_decklink_src_start: enable video input failed".
• Modes 5-12: GstSystemClock is initialized, but I'm getting perpetual "gst_decklink_src_start: enable video input failed" debug messages while no video pop up is shown.

Code: Select all

I was able to reproduce the issue on a different machine using another Intensity Pro card.
Any thoughts?

Are you using the original Intensity Pro or the Intensity Pro 4K? If it's the original then it doesn't support 1080p50 or 60.
I'd also look at going back to an earlier driver such as the 10.5.4's as the 10.6.2 drivers are problematic

I do use the original Intensity Pro card, so that explains a lot - thanks for the insight! That would mean, however, that I can't grab 1080p from the FireTV at all as the device only provides 1080p50 and 1080p60 settings..

Is the downgrade process straight-forward aka download the 10.5.4 version and install?

I've not used it on Linux, but on Windows you uninstall the current version and install the version you want
