[Ffmpeg-devel] Read from a buffer instead of a file

The pseudo class (a C struct with function pointers) handling input 
from 
different url types (pipe:, file:, http:...).
url_open() selects one of them based on the url.
See libavformat/avio.h

No you can avio.h:register_protocol(), 
or just fake an open (open "/dev/null") and override the url field 
in the cookie to your own protocol, as I did.

Sent them on the list in case other ppl are interested, for archival.
