I updated source code.
Now it enumerates all streams from camcorder, enumerates each type of each stream and choose the best for h.264 and aac encoding (not 100% shure about this).

Couple of tests for version from 08. Feb. 2020: Recordings of 5, 10 and 60 sec with preview width 400 and full (commented), all were correct on Win10.

Great job continues!!!

Thanks for test.
I update code
1) add quotes when show all devices, because it can be devices with space at the end of name.
2) add support for enumerating devices with the same name.
3) add support for different Video Input Types with Color Converter DSP help.

This is lovely.

Can this be adapted to acquire images from a scanner?
