[FFmpeg-devel] [PATCH] doc: small ascii diagram on i/o files and streams in ffmpeg.c

[Clément Bœsch]

Hi,

Can anyone check if this is actually correct? I'm not sure it would be of
any use for someone, but it helped me to untangle a few spaghetti while
reading the code; I hope I get it right though.

It certainly should be complete a bit at some point (for instance the
mapping stuff). As is, you might not consider it really worth the effort,
but please correct me if I got something wrong in this diagram.
