it may seem a bit irrelevant here (and other problems need to be
adressed as well), but I've been thinking for a while about a similar thing
to open auxiliary streams such as external subtitles files
(SRT, vob/idx, whatever, ...), to be able to get their frames
synchronized with the streams contained in the main file.

currently I'm doing this as a hack completely external to libavformat,
by fiddling with AVFormatContext->streams (quite dirty).

would it be relevant to discuss that in this thread ?
