This evening I used the build in Windows 10 Camera app on my Surface Pro 4 to record several video clips. However, when I try and open them with Windows Media Player or VLC, I get errors saying "Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file." or the Windows Movies & TV app says "Can't play. Try playing something else. This item's file format may be unsupported, the file extension may be incorrect, or the file may be corrupted. 0xc00d36c4."
Other videos that I also recorded using the same build in app do work. How can I view these other videos?
