Make it possible to play unsupported video codecs

[szaimen]

Is your feature request related to a problem? Please describe. Some video containers are not supported by webbrowsers and probably will not be in the near future.

Describe the solution you'd like Find a solution that makes it possible to play almost all video containers in browsers. One solution would be using wasm and ffmpwg to transcode videos on the fly directly in the browser. See e.g. this article: https://blog.scottlogic.com/2020/11/23/ffmpeg-webassembly.html#:~:text=creating%20a%20streaming%20transcoder
