General:
    * I assume enum vals are guaranteed by rust/c stuff?
    * You need to document how to call the send/recieve and how to drain them, etc. How to loop properly, and if they can be called concurrently, etc.

line 43: No alt-ref / invisible? Or "multiple" if bundled? Does it matter? I'm not sure.

line 85: Mention allocation maybe? Does instatiation imply allocation? I'm legitimately not sure.

line 88/98/etc: Are configs and contexts reference counted? It's really weird to "unref" a config or context to me... Don't you just free it? If they /are/ reference counted... to what end?

commit c870059ddb2131e6bf20c89b164aa69e5531c0e8
Author: Derek Buitenhuis <derek.buitenhuis@gmail.com>
Date:   Fri Mar 23 20:34:21 2018 +0000

    videosource: Do not increment the delay counter when packets are marked as DISCARD

    They do not count towards the codec delay, and are used to signal, for example,
    edit list edits.
