Cannot stream video on iOS

[sayan-futurehook]

I am trying to convert a RTSP stream from some Hikvision camera to webrtc using https://github.com/deepch/RTSPtoWeb . This is successful in converting the rtsp source to a webrtc, and when i open it in my browser it is streaming. Now when I am opening it in iOS it is failing to stream and shows a black screen. Previously I was using https://github.com/deepch/RTSPtoWebRTC to do the exact thing, but some of the camera were unable to stream video, so I tried https://github.com/deepch/RTSPtoWeb to stream and it was successful. It looks like https://github.com/deepch/vdk used for rtsp streaming is having different version used in RTSPtoWeb is different than RTSPtoWebRTC. I tried changing them, but the code was not running.
