[whatwg] File API Streaming Blobs

[Simon Heckmann]

It's actually confidential company data, I  was thinking off. Together with the DOMCrypt API I thought this could be a valid use case. But I think there might be more cases in which it might make sense to preprocess locally stored video data.

Kind regards,
Simon Heckmann

Encryption for DRM, at least, isn't a very compelling use case; client-side Javascript encryption is a very weak level of protection (putting aside, for now, the question of whether the web can or should be attempting to handle DRM in the first place).  If it's not DRM you're thinking of, can you clarify?
