I set up the incoming udp stream according to this article [https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder](https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder)

However, the result is that when I play the result stream of Wowza using VLC, I can only hear audio with HLS streaming and no video.

For RTMP playback, both video and audio are not received.

I checked the log with ./startup.sh , no error was displayed.

Please help me to resolve this. Thank you very much.

Hello.

We could try to troubleshoot this here but it would be more efficient if you open a ticket with support as they will have all the information in front of them.

To open a ticket please send a zipped copy of your /conf and /logs folders, as well as a screen shot of your encoder settings or video/audio codec and fps/key frame details of the source to support@wowza.com.

Please also include link to this thread as a reference.

Thank you,

salvadore

I moved to ffmpeg and it worked okay both video and audio. I think Wowza can not handle this case. It can not detect the video from udp.
