Hello,
We have several streams coming from DVB-S de-modulators and pushed to VLC players as UDP/IP Unicast streams. VLC seems to be having some issues with the stability and hence we want to replcace it with Wowza Transcoder. I see that Wowza Transcoder accepts MPEG-2 streams. But, will it accepts UDP/IP streams like VLC? If so, how I can access them?
If not, what is the best way to get the DVB-S stream directly into Wowza transcoder?
FYI - We have 20+ streams.
Thank you for your time!

Follow this guide to set up an application and start streams:
[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)
Also enable Wowza Transcoder in that application. When you start the stream in Stream Manager, the Transcoder is started.

Hello Richard,
Thank you for your quick reply. With your instructions, I am able to start the transcoder.
But, I am able to get only audio stream in HLS output. I think video stream is missing in the generated .m3u8 file.
My source is in H.264 (part 10)- MP4 format. Is this a problem?
I see that the Transcoder accepts H.264 (Part-2) in the documentation.
Thank you

Also,
I see lot of “WARN server comment - RTPPacketFragmentListReader.skip: Bad” messages in the log.
I also see the following:
INFO server comment - RTPDePacketizerMPEGTS.handleRTPPacket: IMPORT: videoPID[prg:0xd,pid:0x14b5,filter:none]: streamType:H264:27
INFO server comment - LiveStreamPacketizerSanJose.handlePacket[live/_definst_/music.stream]: Video codec: H264

Posting more of the logs might help. Knowing the make/model of the encoder would, and a better analysis of the stream such as the output of VLC Tools-\>Codec Information or from the Mediainfo program would also help. I found this post which may indicate a similar problem: [https://www.wowza.com/forums/showthread.php?12252-Cisco-WVC210](https://www.wowza.com/forums/showthread.php?12252-Cisco-WVC210)
