We recently acquired the Teradek Prism encoder, and when streaming to Wowza we get audio but no video. When streaming to the same Wowza instance with a Teradek Cube, we get video + audio as expected. We’ve tried this on 4.8.13 and 4.8.20, with the same result. Some of the errors we’re seeing are …

[image] Bryce_Seifert: Teradek Prism Hmmm… that’s interesting since we do support the Teradek Prism. Can you tell me the following: What is the protocol you are using? RTMP? SRT? MPEG? Are you sending a 4K stream? What version of Java are you using? I will look for your reply.

Something within the source settings Wowza is not liking. e.g. H.264 profile range compared to frame size and resolution.

i think this is the problem, but I see you have a ticket in and it will get assigned today: You need to have a minimum of Java 11 for Engine 4.8.20. I know you mentioned issues in a different version though so tech support will troubleshoot this accurately. Java support: Wowza Streaming Engine 4.8…

If updating your Java doesn’t work Bryce, I see that tech support has sent you some troubleshooting tips in your ticket to see if it’s a problem with your encoder itself connecting to Wowza although we do support that model.
