I'm running ffmpeg version 4.1 (-version output below) on Mojave. I'm
pretty new to ffmpeg, so please let me know what more I could provide.
Some years ago I ripped a large number of Mini-DV tapes into clips. My
input files are named:

I am trying to use ffplay to crop and scale the 720p 16:9 output from
vmix to provide a second 800x600 4:3 output on a video wall.
The command
ffplay -f dshow -i video="vMix Video" -an -x 800 -y 600 -noborder -vf
"crop=960:720:160:0, scale=800:600"
does exactly what I want, but I can
