Video Call In Background

 Hello ,

I am working on PJSIP. Audio and video call is working fine in foreground but the issue is, When the app is in background, I am able to make call in background but no video is displaying. Any help would be highly appreciated.

When I make a call and pick the call from background, I am getting the errors -

15:48:19.250    pjsua_vid.c  ......Creating video window: type=stream, cap_id=-1, rend_id=0

Code Snippet is -

#define KEEP_ALIVE_INTERVAL 600

- (void)keepAlive {

    static pj_thread_desc a_thread_desc;
    static pj_thread_t *a_thread;
    int i;

    if (!pj_thread_is_registered()) {
        pj_thread_register("ipjsua", a_thread_desc, &a_thread);
    }

    /* Since iOS requires that the minimum keep alive interval is 600s,
     * application needs to make sure that the account's registration
     * timeout is long enough.
     */
    for (i = 0; i < (int)pjsua_acc_get_count(); ++i) {
        if (pjsua_acc_is_valid(i)) {
            pjsua_acc_set_registration(i, PJ_TRUE);
        }
    }
}
