exoplayer rtsp troubles

[ray007]

I'm trying to show a webcam rtsp stream, but all I get is a short error msg in the log:

PlayerError com.google.android.exoplayer2.ExoPlaybackException: com.google.android.exoplayer2.upstream.HttpDataSource$HttpDataSourceException: Unable to connect to rtsp://ipvmdemo.dyndns.org:5541/onvif-media/media.amp?profile=profile_1_h264&sessiontimeout=60&streamtype=unicast

This with a public testing stream (which works in vlc), same with our webcams with internal addresses.

How can I find out what's wrong and how to fix it?

Looks like we need to handling for those
