Linux下onvif客戶端獲取ipc攝像頭 GetStreamUri：rtsp地址（h264、h265）

GetStreamUri：rtsp地址

鑒權：但是在使用這個接口之前是需要鑒權的。ONVIF協議規定，部分接口需要鑒權，部分接口不需要鑒權，在調用需要鑒權的接口時不使用鑒權，會導致接口調用失敗。實現鑒權的方式之一可以調用gSOAP源碼中的 soap_wsse_add_UsernameTokenDigest()函數。要安裝依賴庫OpenSSL

ps：一般情況是如果一開始用的是_tr2（h265），那么獲取信息的時候應該就會一直用tr2（h265）通道。但是有些攝像頭比較奇葩，一開始走的都是_tr2，也就是h265的通道（如get_profiles），但是在獲取onvif的uri（rtsp地址）的時候本該走_tr2（h265）通道，卻走了_trt（h264）的通道才能獲取，我這個攝像頭就是如此。

當然有些h265的攝像頭走的是trt（h264）通道，並不會用到_tr2（h265）的通道。
