Perfectly solve the error loading media: file could not be played error

Recently, I need to use JWplayer plugin to play videos. However, no matter which version or what kind of video I changed, it always prompts Error loading media: File could not be played incorrectly. I finally solved it after a lot of effort.
Solutions:
The IIS default configuration does not add an MP4 file, which results in opening an MP4 file 404.
Open the IIS manager, MIME type

Add, extension mp4, type Video/MP4

Click OK.
