At Michael's suggestion, this patch lets -vn/-an/-sn/-dn work for input
files. Individual streams can still be let through e.g.
ffmpeg -an -discard:a:1 none -i file ...
will let (only) the 2nd audio stream be seen during stream selection and
filtergraph construction.

Subject: [PATCH] ffmpeg: implement input file stream disabling
-vn/-an/-sn/-dn can be set to stop processing of streams
of said type from an input file.
isnt this 2 seperate changes ?
one is adding -vn/-an/-sn/-dn input support and the other is fixing some input
discard issues related to existing -discard functionality
Only one change. I provided an example command syntax to show how to
selectively enable streams while leaving others of the same type disabled.
