Creating a video uploader with JavaScript and api.video
Videos are very large files, and all servers have a limit on filesize upload. The last thing you want your users to see (after waiting for the file to upload) is a "413: request too large" error.
The fix is to use the HTML 5 File API to slice the video into smaller bits, and to upload each smaller chunk.
In this demo, videos are split into 1 MB chunks, but larger sizes are ok (at APi.video, we suggest staying under 100MB per chunk).
All HTML5 and vanilla JS.
All you need is a delegated upload token from api.video. Replace the token parameter in the variable url, nad your own version will be running in no time.
