VP8/Webm support?

[tzarebczan]

How difficult would it be to add streaming support for VP8/webm support? Here's a sample video: https://transfer.sh/AQ8Gp/the-metagame-batman-arkham_1.mp4

Supporting VP8 in a webm container would require a major overhaul. At this point I'm inclined to wait until AV1 is more widely supported and then support that. It seems like there is some support for AV1 in mp4 containers, and some for webm containers, so we'll have to see which one gains widespread adoption.

Of course if someone is willing to fund further work on videostream I can add VP8 sooner :)

Would something like https://github.com/jscodec/jswebm help with parsing webm container?
If so, what type of changes are needed in the main script to support both webm and mp4?
