Is your LCD screen on while you do the capture-movie?
I tried to set viewfinder=1 but it doesn't change anything for me. I seem
to understand that what it does is to enable the live view mode on the
camera by releasing the mirror, which is probably not needed on my M50
since it's a mirrorless.
Regarding your complex setup to view the stream, do you know about this
repo? It's a simple C program which reads gphoto's stdout and display it in
a window, you might find it useful:
