Re: [Linphone-developers] Video issue whlie porting linphone on arm based embedded board.Hi,

Hi,

For your information, ffmpeg is only used to encode/decode video, but display 
is done with libSDL. 
If the warnings come from ffmpeg, then I think there is no reason to think 
that the problem is the LCD display.
