Compress a video on client side web
提问by Safari
I have to upload a video from front-end web to my Django back-end.
我必须将视频从前端 Web 上传到我的 Django 后端。
I need to compress the video before to upload it.
我需要在上传之前压缩视频。
So, I need some libraries (for example javascript libraries) to use on client-side (browser) to compress the video and call my ajax function to upload it.
因此，我需要在客户端（浏览器）上使用一些库（例如 javascript 库）来压缩视频并调用我的 ajax 函数来上传它。
Is possible this?

Can we suggest me something like javascript libraries to make this?
我们可以建议我使用 javascript 库之类的东西来做这个吗？

I found this project. It is a conversion of FFMPEG decoder in javascript language. So you can use it to work images, video and audio files without upload file to server.

No. No browser offers a video encoding API, for JavaScript to tap into. Perhaps one day there will be an official MediaEncoding API - wouldn't that be something?!
不。没有浏览器提供视频编码 API，供 JavaScript 使用。也许有一天会有一个官方的 MediaEncoding API - 那不是什么东西吗？！
