Now that it's merged and in the hands of users I don't have any 
intention of changing the name any more.
We had some chats about about it, but nobody suggested anything that 
people agreed was better, so it stuck.

While "resilient" certainly fits, it could equally apply to regular 
fragmented MP4 (e.g. vMix uses that terminology for fMP4 if I'm not 
mistaken).
The important attribute with this approach is that it's resilient *and* 
compatible, and I'm still not sure how to get that across in name alone.

Obviously FFmpeg has a different target demographic and can use 
something different than OBS, "Hybrid MP4" is just what I came up with 
as user-facing name for the feature at the time.
