Mobile video upload

I want to upload a video (html5) on the mobile. The video file is less than 100m or larger. How to compress the video before the video is uploaded? I can"t find a satisfactory article on the Internet to talk about this piece. How do you usually deal with the compression before video upload on the mobile page? Or if there are any good articles about this, please recommend it. Thank you

it's not possible to compress video in a browser right now. The compression of images and other things has been very reluctant (the rgba attribute value is calculated by canvas.getImageData)
Visual examination can only be uploaded to server and then compressed

P.S. Flash may have a solution.
