[Bug 53750] OpenSeeFace fails to use webcam

[WineHQ Bugzilla]

--- Comment #6 from Prajna Sariputra  ---
I decided to try Wine 8.6 with this, and indeed the FPS calculation in the
output with `--list-dcaps 0` is correct now. As expected the "No frame" issue
still occurs as well as the crash with OpenCV (aka using `--use-dshowcapture
0`).

Although, currently I have a different webcam which supports either YUYV 4:2:2
from 176x144 to 640x480 or MJPEG from 176x144 to 1280x720, and I noticed that
the supported format shown by OpenSeeFace with `list-dcaps 0` is all XRGB.
