Ingest UDP stream with H264 to Wowza

Wowza Streaming Engine
1

Hi,

I’m trying to ingest a UDP stream into Wowza and play it back, this is despite following the articles on the Wowza forum (https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder.

Using VLC media player I can open the stream being published on multicast from the encoder with ‘vlc udp://@232.25.12.42:10000’

In VLC media player under Tools -> Media Information -> Codec Tab I see the Codec being “H264 - MPEG-4 AVC (Part 10) (h264)”

On standard definiton video the Codec is "MPEG-1/2 Video (mpgv).

I have an Application.xml file which looks like this below:

In the content folder I’ve created an mpegts.stream file which contains udp://232.25.12.42:10000

In the Wowza console when I start the stream I get the following outputs…

---------- The above just repeats over and over --------------

From the output it looks like it’s reading something to do with the streams, but I can’t play back any video at all if I try connecting to the stream over rtmp (or anything else).

Any help is really appreciated.

Thanks,

Hi,

We have a troubleshooting log messages article which can be found here,

How to troubleshoot error messages

I did a search for “RTPMediaCaster.Reconnector” as this appears in you logs and found two possible matches listed below:

Cause: This MediaCaster problem is most commonly caused by some kind of network error. For example, the SHOUTcast server isn’t turned on. Here we see a live stream started, then warnings and errors that indicate that the Wowza Media Server was impacted by a dependency failure.

Cause: 2 or 4 bind lines, followed quickly by 2 or 4 unbind lines indicate a failed UDP session, ports blocked. Typically the problem is with the firewall on the computer where Wowza Media Server is installed. It could also be the router, proxy in the environment, or carrier network in RTSP streaming application.

Did you use stream manager to start the stream or has this been added to StartupStreams.xml?

If neither of these possible causes are able to help you troubleshoot the issue I recommend you open a ticket by sending an email to support@wowza.com.

Please include a zipped copy of the [Wowza-Install]/conf and [Wowza-Install]/log directories for analysis, a copy of the .stream file in use and a link to this thread for reference.

Many thanks

Jason

Hi,

Thanks for the update, I can see this is now being handled via the ticket system.

Hi,

Thanks again for posting the issue and the detailed resolution for overcoming this encoder problem, this will help many others with the same issue.

I’d also like to thank you for your feedback I will pass your comments along to our development team who will review them.

Regards,

Jason

Hi Jason,

Effectively the encoder and the Wowza Server are sitting on the same Debian box. I can run VLC from another host on my network and connect to it via UDP Multicast - there’s no firewall placed anywhere.

The stream is started using StartupStreams.xml.

I think my best course of action is to do as you suggested and log a support ticket.

Many thanks for your assistance - I will post the outcome here.

Jason,

I managed to resolve this - I have notified support.

My encoder seems to announce all of the Program PMT’s as it finds them in an arbitrary order.

I noticed from the output below that Wowza seemed to be selecting the first PID in the list but with mumudvb (the encoder) you select only specific channels to multicast (in my case I was selecting channel 3815 with PID 0x105). As you can see in the output Wowza is trying to Start Stream 0x105 which is PMT 3900.

INFO server comment - [live/definst/mpeg.stream]: MPEG2MPTS:StartStream: PID: 0x105

The solution was simple after a quick search around the forums which this article explains: https://www.wowza.com/docs/how-to-select-mpeg-ts-stream-by-program-id-and-also-audio-language-by-pid

I simply put selected the program id to stream in the mpeg.stream file.

udp://239.1.1.1:5500?programID=3815

And now it works!!!

I’m unsure why but VLC was able to detect that channel 3815 was being streamed - I’m unsure if this is simply the loose nature of VLC or if it’s an improvement that can be made to Wowza.

Many thanks for your assistance.
