Hi Benny,
Effectively, my question was wrong. I have two steps :
- init
+ pjsua_create
+ pjsua_init
+ pjsua_transport_create
+ pjsua_media_transports_create
+ pjsua_start
- connect
+ pjsua_acc_add
I call "init" and just after "connect". So in this case, the CPU
increase to 80%, just because micro is activated. But I don't need micro
before the communication is established.
The CPU problem comes from Darwin and not your implementation. I think,
because this problem doesn't exist on windows and especially because I
have the same with micro without pjsip ;-)
With this description, perhaps you have another solution to deactivate
micro.
Thanks in advance
Samuel
