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.
