I'm now using Windows 10. When trying to view the VideoSnaps in the built-in Windows 10 movie viewer, I only hear sound and can't see the video.
It appears that the VideoSnaps use Planar 4:4:4 YUV encoding. Videos that are in Planer 4:2:0 YUV work with the Windows 10 movie viewer.
Is there anyway that you could output the mp4 files using a different codec?
