White screen on second channel

General
1

Hello,

I’m having a issue where the second channel only outputs a white screen. Right now it’s as key and fill are going through the same channel. The graphic is transparent but I can still see the colors and shapes of the intended graphic. I didn’t code the file, it was already on the computer. If anyone can explain what is going on, that would be much appreciated. Thank you.

This is the config file.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <paths>
    <media-path>media/</media-path>
    <log-path>log/</log-path>
    <data-path>data/</data-path>
    <template-path>templates/</template-path>
    <thumbnails-path>thumbnails/</thumbnails-path>
  </paths>
  <channels>
    <channel>
        <video-mode>PAL</video-mode>
        <consumers>
          <screen>
            <device>1</device>
          </screen>
          <system-audio />
        </consumers>
    </channel>

You do not have a second channel. You only have a screen output. What do you expect to see where? Do you have a Decklink card?

There is a decklink connected, a duo 2. It can’t be seen by the computer though. The decklink software cant read it. If it cant be seen would it still be sending signal out?

Yes, I was thinking something like that. You see, the reason why Caspar is not seeing the Decklink Duo 2 is, because you did not told it to do so. You can see if that helps or just use the magnifier icon in the top right corner of this website to search for posts about “Decklink Duo 2”

After the file config. it has a gap with an exclamation point.<!–
In the rest of the file I can see it mentioning device 1. I’ve never coded, don’t really know what to look for that would look weird. I tried posting the rest but it wouldn’t show up.

The <!- is starting a comment. That means everything between <!- and -> is treated as it is not there. So what you actually need is a config like the one in the link I sent you. Or you could try with this:
