[vlc-devel] Re: how subtitles work??

[Václav Koldus]

I've got special filter to render images or text loaded from external 
files making videotext info (crawling text, changing photos, etc.). All 
this is defined in one xml file. But I need to load different xml file 
for different video files (or sometimes to don't load/show anything).

What I need is the mechanism that allows me to render/load different 
things depending on played file. Can marquee filter do this? If yes I 
could use similar procedure, I just need to know how to do it.
