当我收到视频呼叫时，我的应用程序崩溃了。
以下是视频配置的代码：
acc_cfg.vid_in_auto_show = 1;
acc_cfg.vid_out_auto_transmit = 1;
acc_cfg.vid_wnd_flags = PJMEDIA_VID_DEV_WND_BORDER.rawValue | PJMEDIA_VID_DEV_WND_RESIZABLE.rawValue;
acc_cfg.vid_cap_dev = PJMEDIA_VID_DEFAULT_CAPTURE_DEV.rawValue;
acc_cfg.vid_rend_dev = PJMEDIA_VID_DEFAULT_RENDER_DEV.rawValue;
这是我接受呼叫时使用的代码：
call_opt.aud_cnt = 1;
call_opt.vid_cnt = self.isVideoPossible(callId: id)
print("video count", call_opt.vid_cnt)
pjsua_call_answer2(id, &call_opt, 200, nil, nil) // 200 PJSIP_SC_OK
我已经看完日志，发现相机打开了，然后突然我的应用崩溃了。

有人可以帮我吗？
提前谢谢！
