Hi,
I have a problem with registering threads (via method
py_pjsua.thread_register()). I attached a complete code below. The
interesting part is at the bottom in the "for" loop (rest is taken from
Python example from site). When I make call from the same thread
everything is ok (actual code). When i uncomment first line in the loop
(and comment second) i have error:
Assertion failed: !"Calling pjlib from unknown/external thread. You must
" "register external threads with pj_thread_register() " "before calling
any pjlib functions.", file ../src/pj/os_core_win32.c, line 521
My question is - where should i put thread registration code ? What
about function app_init() and add_account() - should i call this methods
in each thread ?
Any help is appreciated.
Chris
