Hi again,

I'm still having the described trouble. Is there any help?
My workaround to comment out the described function call in linphonecore.c 
doesn't seem to be that
good for the whole thing, even though Linphone compiles successfully.

mediastreamer2/src/nowebcam.c seems to be "infected" by ffmpeg code (function 
calls...) which is the
reason I can't reinclude it for compilation in mediastreamer2/src/

Any help?
