Thanks vimlesh to solve this problem
I am using Caspar CG server 2.07 and simple-video-playout for footabll graphics.
There was a problem I face when I fire the graphics and switcher take. It was not alpha.
because I use a card that was only one output
Vimlesh advice me to use a card that have multiple I/O. I change My card and use Deaklink Duo 2
This card have 4 bidirectional I/O
Here is my Configure file
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<paths>
<media-path>c:/casparcg/_media\</media-path>
<log-path>log\</log-path>
