Comment (by Kirill A. Korinsky):
1. The same device works on macOS laptop, I haven't tried ffmpeg, but it
works with elgato cam hub, and in Safari.
2. OpenBSD and Linux has two different implementation of V4L2 stack, I
doubt that both of them has the same issue.
Also, this webcam supports both isoc and bulk endpoint, and such behaviour
can be observed via both endpoints.
And, finally, I had tried mplayer and it works on OpenSBD.
I had run it as: mplayer tv:// -tv
driver=v4l2:device=/dev/video1:width=3840:height=2160:fps=60
and mplayer playes ffmpeg-framerate-60.mp4 as well.
All of this smells like a bug in ffplay / ffmpeg.
