Video fail to stream

Dear Support,

I have try to stream a channel and get below error message. My stream url is rtmp://110.164.128.134:1935/CH30/CH30.stream .

No suitable decoder module:

VLC does not support the audio or video format “undf”. Unfortunately there is no way for you to fix this.

you may download the source file from this url http://110.164.128.190:8888/tmp/239.2.8.34.mpg .

There is an audio but there is no video display.

Please let me know what is the solution to make this stream to be work.

I was getting that error too a couple of VLC versions ago. I have 2.0.6 at present and not getting that problem with your file.

Hi,

Did you follow this guide for the configuration and setup for publishing of a multicast MPEG-TS live stream?

Hi,

What URL do you have in your CH30.stream file?

Is it the streaming URL of your live source? Can you please copy/paste in the contents of that file so we can see how that URL looks like?

What does the Wowza log say when it tries to connect to udp://239.2.8.34:2000 ?

Hi Richard,

Have you try please this url rtmp://110.164.128.134:1935/CH30/CH30.stream using version 2.0.6 . Cause i have tried same in version 2.0.6 but it’s still failed.

Hi Support,

Any reply for case. I’m still fail to stream.

Dear Support,

Below is my CH30.stream file in content folder. Sound like the video codec is missing in wowza to support this stream. I can use the udp address to play use vlc player. at the same time i try to use another rtmp server where i use ffmpeg to sent the stream as below and it’s works.

/root/bin/ffmpeg -re -i udp://239.2.8.32:2000 -vcodec libx264 -g 10 -s 720x576 -ar 44100 -ac 1 -f flv rtmp://110.164.128.135/CAG/CH29.stream

cat /usr/local/WowzaMediaServer/content/CH30.stream

udp://239.2.8.34:2000
