  • Ticket #2251 – Description

    initial v2  
     1The old issue of #2115 and #1464 still persists, because it can affect other callbacks as well, not just on_call_state(). If inside any pjsua callback which holds PJSUA LOCK, the app calls any pjsua conference/video conference API (which will try to acquire conference mutex), the deadlock can potentially occur with media ports' callbacks, which hold conference mutex, and if the app calls any pjsua API from there.

     3The best solution seems to be not holding the conference lock when calling media port's eof callbacks. In this ticket, we will try to achieve this by using media event mechanism to call those callbacks.
