For a libavformat-using program that does its own transports? Sure, I'm
already doing that in other projects. For anything that wants to use the
ffurl transports -- and in particular, stream from the ffmpeg(1) client?
I don't see how that would be possible, unless I'm misunderstanding what
you're suggesting.

I believe this was already covered in the commit message...? But yes, Cubemap
is my own project, and Metacube is its framing protocol.

I'm not seeing a lot of love for this patch, so I won't be pursuing it any
further -- I wanted to upstream it due to user requests, but it is small
enough that it can live in my own tree pretty much indefinitely.
