Hi,

thanks ....

i will change from 352x288 to 176x144 and try.

Also, which codec will be better to use. I am right now using four codecs,

Mpeg4-es
H263-1998
Theora
X-snow

It is most probably because of encoding is to much burden for your arm processor... and the solution.. there is no solution actually rather than upgrading your cpu.. but you may try to lower the fps , resulotion vs..

I am connecting PC and ARM board back-to-back, there is no network lag, its 10/100 Mbps.

Both sides, same version of linphone (3.2.1) is used.
