You forgot to set the desired player plug-in on your media source asset. UE4 will pick a suitable player automatically if not set. Since both VlcMedia and WmfMedia support RTSP streams, UE4 chose to play it with WmfMedia in your case. However, WMF may not support the actual data format in the stream, so the resolving of the media source seems to fail (i.e. it can't be opened).

Set VlcMedia on your media source asset as the default player and try again. If you are opening the RTSP stream using a URL string from code, then set the DesiredPlayerName property to "VlcMedia" on your MediaPlayer asset before opening the URL.

I think I did set the VideoLAN Media Player (VLCMedia) on my media source asset, I just set Windows player,other platform players set to Auto, But when package project still the same problem,In Editor mode everthing is ok. Did I missing something else?

Ok, I know what's happening. There was actually a bug that prevented VlcMedia from working in packaged builds. It is fixed for 4.17. You will need these changes: https://github.com/ue4plugins/VlcMedia/commit/cf82a58b1fe433f793b16b9a31a715f7d6a3cab1
