Try also with mpv.
Thanks for that idea, I had a quick look at mpv with the following:
mpv.exe "test_vid_1280x720.mp4" --osc=no --screen=2 --no-border
--geometry=800x600 --panscan=1
However I don't know how to get mpv to take the directshow video input I
need?
It should be available via: mpv "av://dshow:vMix Video"
Thanks for the suggestion, I got the following error when I tried it:
mpv "av://dshow:vMix Video"
Playing: av://dshow:vMix Video
[ffmpeg/demuxer] dshow: Malformed dshow input string.
[lavf] avformat_open_input() failed
Failed to recognize file format.

Trying ffplay worked with:
ffplay -f dshow -i video="vMix Video"

But I still don't have a way to direct ffplay to output on a specific
monitor.
