Fair enough. I'm happy to let it drop.
I'd rather use ffmpeg unpatched, but I'd equally like to be able to signal
back to other objects in a a GUI the connection state, the way I'm doing that
at present is by wrapping the existing format and adding my own little bits
of signal code on the path through. The priv_data pointer in my patch is to
let my wrapper format have some way of getting back to the creating object.
It's the only way I can see to do this:
This doesn't seem like a crazy thing to want to do with a library like ffmpeg.
Anyway, as I say, I'm happy to let it drop.
