Just hit this too. It'd be really great if stubber could handle `download_file` and `upload_file`

I would _love_ to have this. For example, this would open up a whole world of potential encoder options on embedded platforms, where encoding is often implemented via hardware.

And one more comment: I'd argue mkvmerge does not support dynamic format changes, because they'd need to construct stream-level data to indicate a format change (completely possible without re-encoding, btw)....

This might also be a bigger discussion of how to abstract an interface to all of the encoders MediaRecorder potentially uses to expose more fine-grained encoder settings (for example, rate...

@dontcallmedom thank you for sharing the contribution requirements. I'll figure that out with my employer (HireVue); I'll email you regarding that. Thanks!

At the risk of making something complicated, I'd really like a "quality" setting (which implies a variable bitrate) in addition to the hard-coded bitrate. for example, with x264, you can...

@miguelao honestly, I'm not sure of a clean way to abstract this because it's ultimately highly dependent on the encoder implementation, as well as individual browser use of those encoders....

Honestly, MediaRecorder probably should have produced this output from the beginning, for a couple reasons: 1. The big issue is getting _encoded_ audio and video. It's prohibitive to have javascript...
