更新時(shí)間:2019-11-20
音頻通話中,通話的一方發(fā)起音頻通話切換為視頻通話。
音頻通話已建立,主被叫正在通話中。
通話中,主被叫雙方均可以發(fā)起音頻轉(zhuǎn)視頻操作。

只有被請求方用戶接受時(shí),才需要此步驟。
若用戶長時(shí)間沒有響應(yīng),被請求端應(yīng)用程序應(yīng)該自動(dòng)拒絕轉(zhuǎn)視頻的請求。建議時(shí)間為45s。

若被請求方接受視頻請求,請求方向UI上報(bào)打開視頻通知事件TSDK_E_CALL_EVT_OPEN_VIDEO_IND,UI根據(jù)事件顯示遠(yuǎn)端和近端視頻窗口;被請求方點(diǎn)擊接受后,UI顯示遠(yuǎn)端和近端視頻窗口。
若被請求方拒絕視頻請求,請求方向UI上報(bào)遠(yuǎn)端拒絕請求打開視頻通知事件TSDK_E_CALL_EVT_REFUSE_OPEN_VIDEO_IND,UI銷毀遠(yuǎn)端和近端視頻窗口。
