Do any of the Decklink cards support output of the Ubuntu Desktop via the SDI out? (As I believe some do on Mac)

Yes, capture the desktop using ffmpeg and pipe the raw video to bmdplay.

For example :

Code: Select all

ffmpeg -f x11grab -r 25 -s 1280x720 -i :0.0 -vcodec rawvideo -pix_fmt uyvy422 -an -f nut - | bmdplay -f pipe:0


You can also add audio from an alsa audio device if you need audio.
