Active incoming stream from Blackmagic Web Presenter 4K, but no outgoing streams work

Wowza Streaming Engine
1

Greetings

I have a RTMP stream coming in from a Blackmagic Web Presenter 4K. The stream shows as active in Incoming Streams. However, none of the test streams work in VLC or elsewhere. I know I can stream from this server, as my VOD stream works great on all formats in LVLC.

I know I should test the stream from the BWP4K, but, I’m a bit of a newbie with it, so I’m not sure if I’m using the correct URL to access the stream. However, if the Wowza Application is seeing the stream as active does that not mean that the stream is valid?

I’ve had a look through the forum, and the Blackmagic forum, and Google, and I can’t find someone using quite the same setup as me. Any help would be appreciated.

Please post the URL that you’re trying for playback. Also; the first thing I’d do to troubleshoot is check the access logs (in /usr/local/WowzaStreamingEngine/logs). It could be that the audio and/or video format isn’t supported with the playback protocol that you’re using (e.g. HLS)

Hi, Karel. Lots of information here, and some chunks from the logs (broken into three sections: error message from VLC client, where I created the Application, and one of the stream starts). Any help is appreciated.

The URL I’m trying (which I got from “Incoming Streams” from the Application) is “rtmp://10.0.7.23:51051”

10.0.7.23 does match the IP address of the BWP4K. There doesn’t appear to be anywhere that I can select the port in the BWP4K interface, so I don’t know if I can change that.

As for logs, here are the last couple of times I tried to connect to the stream, and the first of many keyframe messages that went on into the night. I have to admit that I’m not entirely sure what the logs indicate, but I’m pretty sure those WARN messages are the attempts VLC made to connect to the HLS stream. Earlier in the day I did try the MPD, RTMP and RTSP streams and they didn’t work either. I found these in the logs, but didn’t want to post too much below.

So, if I’m reading this correctly, the VLC client is trying to create a connection to the stream, but it fails.

Here’s the part of the log where I created the Application. I’m not sure if this helps.

And here is one of the starts of the stream. I see a WARN in here about the stream name missing or being too long. I’m not sure exactly what that means, as I don’t think that’s true:

If the BWP4K supports pushing the stream from the device to the server over RTMP, then the best is probably to start here: https://www.wowza.com/docs/how-to-set-up-live-streaming-using-an-rtmp-based-encoder

I would disable transcoding for now. Apparently your server isn’t powerful enough to transcode a 4K stream. Transcoding is a rather resource-intensive process, particularly for 4K streams and I recommend to use a GPU like NVidia Tesla (or virtual server with GPU like AWS EC2 g4dn, or a similar server at Azure)
