After my previous email I have created simple plugins to send and receive information through video. <a class="moz-txt-link-freetext" href="https://github.com/reinismu/gst-data-video">https://github.com/reinismu/gst-data-video</a> Basic example line `<code>GST_DEBUG=*:3 datasrc ! video/x-raw,framerate=25/1,width=1920,height=1080 ! datasink</code>` works fine, but when I try to send the same stream to decklink card `GST_DEBUG=*:3 gst-launch-1.0 datasrc ! video/x-raw,framerate=25/1,width=1920,height=1080,format=UYVY ! decklinkvideosink device-number=1 mode=1080p25` I get ``` Setting pipeline to PAUSED ...

Maybe someone can point me in the right direction? Thanks! </body> </html>
