HD Extreme 3D+ configuration issue

General
1

Hi,
I have Decklink HD Extreme 3d+, My goal is to use the input signal, and overlay it with html,

In the caspar configuration (casparcg server 2.3.3) I set it up as 1…
I can see my html on the output, but when I try to load the decklink input - caspar is logging:
“Decklink hd extreme 3d+ [1|1080i5000] Could not enable video input”

If I change the configuration to 3 for example, outputs 1 and 2 become a loop of the input channel, but I can see input #1 if I route it to 1-1 on my , it doesn’t go out to SDI (I assume because 3 is not a valid output, but this means the input is working properly)

I’ve tried many configurations but this is my configuration currently:

   <channel>
        <video-mode>1080i5000</video-mode>
        <consumers>

  <decklink>
            <device>1</device>
            <embedded-audio>true</embedded-audio>
            <latency>normal</latency>
            <buffer-depth>3</buffer-depth>
        </decklink>

            <screen />
	
        </consumers>
    </channel>

anybody has any ideas for me?

Thanks!

This card can only be used as either input or output, not both at the same time. But it can do „internal keying“, that means it can key graphics over pictures, that are feed trough it. The config part should look like that:

<channel>
	<video-mode>1080i5000</video-mode>
	<consumers>
		<decklink>
			<device>1</device>
			<embedded-audio>true</embedded-audio>
			<channel-layout>stereo</channel-layout>
			<latency>normal</latency>
			<keyer>internal</keyer>
			<key-only>false</key-only>
			<buffer-depth>3</buffer-depth>
			<custom-allocator>true</custom-allocator>
		</decklink>
	</consumers>
</channel>

Finally back playing with CasparCG, I missed you all!

Am trying to get Key and Fill output to send to a ATEM.

Can’t get the right configuration as I am getting the Fill out where the fill should be, but also fill out where the key should be! (testing with a monitor)

            <decklink>
                <device>1</device>
                <key-device>device + 1</key-device>
                <embedded-audio>true</embedded-audio>
                <latency>normal</latency>
                <keyer>external</keyer>
                <key-only>false</key-only>
                <buffer-depth>3</buffer-depth>
            </decklink>

Also curious what the

<custom-allocator>true</custom-allocator>

does?

Are you using windows? Have you configured the card in the decklink software? They should be set to 1+2. If using ubuntu this is by default.

I am also interested in <custom allocator>

custom-allocator hasn’t been a valid setting for a few years.

The only thing that looks wrong with that config block is the <key-device>device + 1</key-device> isn’t doing anything right now, but that is fine as you dont want to set it

<key-device>device + 1</key-device> is not valid XML. It may prevent the whole config to load. You better get rid of that line entirely.
