[mediacapture-record] Unclear on mine type paramters

fluffy has just created a new issue for 
https://github.com/w3c/mediacapture-record:

== Unclear on mine type paramters ==
It has the text 

> The container and codec format(s) for the recording, which may 
include any parameters that are defined for the format.

Not sure what types of parameters are included here. Can I provide 
H.264 fmtp like parameters?
