[PD-dev] videogrid + pd-extended 0.42.5

[lluis gomez i bigorda]

hi all,

yes, we say here "esoteric bug" cause we cannot understand at all why if 
Gem is linked against libavifile it beaks our ffmpeg code. videogrid is 
not linked against libavifile !!! that's crazy? or not?

and more, if we load videogrid before Gem the crash desapears. why the 
lib load order can change behaviors of a library in that way? maybe some 
namespace conflict?

anyone can put a bit of light on this please? we are just belivers of 
almighty pd wisdom. you know ... :)

thanks in advance,
ll.
