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

[Simon Morlat]

Hi,

The "we are late " messages mean that linphone is out of CPU: the board isn't 
processing audio and video enough fast for real-time, which causes discarded 
RTP packets.
I recommend you to set bandwidth settings like this (in ~/.linphonerc, I guess 
you are using the console version)
[net]
download_bw=128
upload_bw=128
This will force linphone to use low-quality settings to be conformant with the 
above bandwidth limitations, and as a consequence, because frame-rate is 
lowered, and video size is lowered, it usually consumes much less CPU.
