Great app, but new update has a bug

Since the new update, adding a new SRT connection is bugged. It forces you to separate the streamid from your url, but when you do this it throws an error about not being able to connect: “Streamid parameter not found in url”. This prevents me from adding a new SRT source. Hope this gets fixed soon!!!!!

Reactie van ontwikkelaar ,

You need to specify streamid in a separate field of connection setup form. If you still face problems with it, please send us more details to so we could help.

Goed en eenvoudig

Een van de betere apps voor streaming naar RTMP-servers!

File not recording

Great app. Streaming works well. Recording doesn't work though. App doesn't ask for permission to access the media library. Can't change settings to make it work.
