I'm trying to connect to a HIKVISION camera, after many hours I'm still stuck, any suggestions?

How do you connect, by specifying video URL or by specifying CameraHost:CameraPort and searching for the camera?

I have tried both ways without any luck, I'm doing it remotely, trying to demonstrate a prototype using RVMedia. It is my first time connecting to a camera that uses H264 protocol. When I did it via Host the Searching Animation appears, and a status 1 was generated, when I tried via URL nothing happened. In both situations the camera IsVideoPlaying propertie is set to True even though there is no video visible.

Do you use FFmpeg or GStreamer, does this camera requires username and password?
If you call SearchCamera, is OnSearchComplete called? If yes, what's the value of Status parameter?

The camera has user and password, I Tried with FFmpeg too, the return status is 1.

Nonzero status means unsuccessful search.

Note that FFmpeg is required if to display H.264 videos from IP cameras.
While both GStreamer and FFmpeg can be used to display H.264 video streams (DeviceType = rvdtRTSP or rvdtHTTP), for IP cameras (DeviceType = rvdtIPCamera) FFmpeg must be available for the application.

1) Make sure that you use the newest RVMedia version, 7.3.3. It fixes several authentication errors in the previous versions.
2) Check if FFmpeg is really used by RVMedia (RVCamera.IsSupportedFFMPEG must return True)
3) For any case, assign LoginPrompt = True
4) If you search for H.264 stream, RVCamera.VideoFormat must be rvvfH264.
5) If you know the exact video URL, simply assign it to URL property and call PlayVideoStream, without searching.

After trying all your suggestions, there is still no video showing, even though now there is no Status message, the IsVideoPlaying property is True, the CamView shows this Title (rtsp://10.15.1.16/cam/realmonitor). I replaced al the FFMPEG dll with this ffmpeg-4.2.2-win32-shared that are the latest.

If you can open this video for me, I'll try to connect and see what's wrong.
