Can't get HDMI input to work. Colour bars only.

Hey,

I'm trying to use bmdcapture on Fedora 26 with an Intensity Pro 4k card to capture hdmi video.

I've tried with three different sources, a Raspberry Pi, a Win10 laptop and a freeview set top box.

I've run through every single mode and I've tested the devices with a monitor. The cable is fine and there is video.

I double checked I was using the right hdmi plug on the capture card.

I can only get colour bars.

Analog input does work, but I want to use hdmi. I've tried this on a different machine with a different (identical) card and hdmi doesn't work on that either.

This is the command I'm using:

./bmdcapture -m 13 -C 0 -V 3 -F nut -f pipe:1 | ffmpeg -i pipe:0 -analyzeduration 50 -probesize 32 -c:v libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f mpegts udp://10.249.0.14:1234

I'm actually using a slightly older version of bmdcapture (not sure how old, but the source is a bit different). I tried compiling the latest and it will compile, but I get this error message when I try to run it.

Could not obtain the IDeckLinkConfiguration interface - result = 80000004

Does anyone have any ideas? I feel like I've tried everything.

Thanks.

To update, I've also tried setting the hdmi_pixel_encoding to YCbCr full on the pi and hdmi_ignore_edid=0xa5000080 so that it doens't try to use an EDID.

running /opt/vc/bin/tvservice -s shows: state 0x12000a [HDMI CEA (19) RGB lim 16:9], 1280x720 @ 50.00Hz, progressive

and I am running bmdcapture in mode 13 - 720p50.

Still getting colour bars.

For any future readers, I fixed this by firstly installing drivers that matched the SDK I compiled against. I then updated the firmware on the blackmagic card.

Lastly I set pixel encoding to rgb10 with -p rgb10, then I was finally able to capture hdmi input from a raspberry pi.
