Using Flash for user submitted videos?

I am looking at pivoting a project I've been working on into a plugin to allow web users to record and upload video in-browser, which to my knowledge has only been done with Flash.

Has anyone come across an alternative to Flash for this purpose, and if not, what are your impressions of Flash as it exists today? My dev team keeps telling me we could market this plugin because Flash is unstable/outdated, but I don't know if it's a big enough problem that people would actually pay for it.
