[FFmpeg-user] ffplay on second monitor

Try also with mpv.

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.
Exiting... (Errors when loading file)


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.
