Hey @alvestrand, sorry to resuscitate an old thread, but I currently have a use case for getting the raw data, and a scenario that doesn't seem to be currently covered:

I have an application with fairly long-lived streams (e.g. 1 hour long at a time), and I'd like to provide users with a way to capture short clips of the most recent, say, 15 seconds.

Currently it seems that creating a buffer of the most recent data directly from the MediaStream is not supported.
Also, it seems that keeping a buffer of the most recent blobs from MediaRecorder doesn't work, due to the spec stating that
> When multiple Blobs are returned (because of timeslice or requestData()), the individual Blobs need not be playable, but the combination of all the Blobs from a completed recording MUST be playable.

What do you think of supporting this scenario, or is there an interface I'm missing? Thank you!
