I am not sure what you mean. I think the only practically deployable 
way to scan for subtitles is when opening a directory. It can either be 
done by the directory demuxer (ugly) or by a for-directories stream 
filter (less ugly).

It won't work if the input item was not created by the directory 
demuxer. But I fail to conceive an acceptable solution. Blocking 
scanning during input initialization is a non-starter for performance 
reasons. Non-blocking scanning is a non-starter because we would need 
the subtitles immediately (unlike covert art), and because it could 
overload the network in some cases.
