Video file isn't supported while it all looks ok locally

[Lin M]

Hi folks,

I want to embed a video on by github blog (based on Hexo). I just added a

<video src="video.mp4" width="320" height="200" controls preload></video>

in the markdown file and put the .mp4 file in the same folder with the page. It all worked when I tested it locally but after I pushed it to github and it can not be displayed. Can anyone help me about that? Thank you very much!

Best,

Lin
