Re: [Linphone-users] Linphone console using 100% CPU

[alex]

Hi Simon,

Thank you for your reply, I was having the CPU usage issue regardless of 
which codec I tried. The machine is a 3Ghz Pentium 4 Prescott CPU with 
2GB of RAM, no X server is running, its pure text mode only. Apache, SQL 
and other things are running on the machine and I rarely see the machine 
use more than 2% of CPU.

Is there any solid documentation of all the .linphonerc options for the 
latest version of linphone? I kept running across documentation for much 
older versions which wasnt terribly helpful.

funnily enough when I do a man readline, under "bugs" I found this:

BUGS
      It's too big and too slow.

If the main loop is polling for input from the keyboard, wouldn't it be 
possible to use another function like scanf("%s",&inputbuffer);
Such functions work under DOS, which is where I learnt C, I am unsure if 
the gcc libc supports this *shrugs*

Let me know what you think.

Thanks!
Alex
