Transcode from VLC (MPEG2 stream)

Wowza Streaming Engine
1

Hi, please Help me!

I’m try to transcode Stream from VLC (MPEG2). VLC show that:

stream1

Type: Video

Codec: MPEG-1/2 Video (mpgv)

Resolution: 704x576

Ferq: 50

Stream2

Type: Audio

Codec: MPEG Audio layer 1/2/3 (mpga)

Lang: Russian

Channels: Stereo

Freq: 48000Hz

Bitrate: 192 Kbit/s

i send this stream to WOWZA by UDP (legacy)

:sout=#duplicate{dst=udp{dst=xxx.xxx.xxx.xxx:10000},dst=display} :no-sout-rtp-sap :no-sout-standard-sap :ttl=1 :sout-keep

and wowza write in log

WARN server comment 2012-01-19 15:58:25 - - - - - 13.881 - - - - - - - - LiveReceiver.startDataPacket[live/definst/myStream_360p.stream]: Data packet sync issue.

what is i`m doing wrong ?

sorry for my English :slight_smile:

Are you able to play the stream in LiveVideoStreaming example player?

Server: rtmp://[wowza-address]:1935/live

Stream: myStream_360p

What is myStream? You are using VLC, I would expect a .stream file or StreamNameAlias alias

Are you doing something like this, but with mpeg 2?:

https://www.wowza.com/docs/how-to-use-vlc-as-a-live-stream-encoder-with-wowza-media-server-mpeg-ts

If so, then you want to follow this guide to start the stream:

https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder

Try encoding and starting a stream following these guides, then playback.

Server: rtmp://[wowza-address]:1935/live

Stream: mpegts.stream

If the above plays, and the Wowza Transcoder is enabled with default transrate.xml, then this should work:

Server: rtmp://[wowza-address]:1935/live

Stream: mpegts.stream_360p

Richard

Scratch the playback of source in that case. Send mpeg2 from VLC to transcoder and playback:

Server: rtmp://[wowza-address]:1935/live

Stream: mpegts.stream_360p

Richard

It looks like you are trying to play a live stream in an application with StreamType “default”. Change the StreamType to “live”

Richard

6

If you are using VLC why use MPEG2? You can use VLC to transcode to h.264. This can be done from the VLC GUI.

7

Yes, that is the audio watermark which is part of the trial license.

Hi,

The better way is to use MPEG-TS out of VLC, if you can. Take a look at this article for more details and a link on that

page regarding MPES-TS streaming to Wowza:

https://www.wowza.com/docs/how-to-use-vlc-as-a-live-stream-encoder-with-wowza-media-server-mpeg-ts

no, and this error in log is permanently

many many strings

10

no no no i use VLC ONLY to transmit stream from my local net to WOWZA server. i dont use any transcode option in VLC

when i try to publish and play mpegts.stream

Server: rtmp://[wowza-address]:1935/live

Stream: mpegts.stream

Ican`t see video and in the log i have strings about Data packet sync issue.

This error starting always when i try to publish stream in stream Manager…

11

when i try to send this stream into another wowza server (2/2/0) it work good.

video doesnt work but into log no errors about sync only unformat…

12

when i turn off transcode

none

and play my stream

Server: rtmp://[wowza-address]:1935/live

Stream: mpegts.stream

server comments

LiveStreamPacketizerSanJose.handlePacket[live/definst/mpegts.stream][mp4a.40.33]: MP3 Audio: Audio is not MPEG1 Layer 3. May not be playable by Flash player.

but if i set

transcoder

In log write many strings about

LiveReceiver.startDataPacket[live/definst/myStream_360p.stream]: Data packet sync issue.

Richard, at all thanks for all your comments!!!

Can i send my stream to some yuor wowza server, that you will see on it ?? please, i have no any ideas…

Dear Support,

We are using a transcoded output from VLC and would like to feed Wowza with this data in mp2v or h264 codec. Our output format of VLC is RTSP, but somehow Wowza can not handle the stream and it continuously leads to critical errors according to its log files:

:mad:WARN server comment 2013-10-25 13:03:05 - - - - - 3271.371 - - - - -

      • RTPSessionDescriptionDataProviderBasic.getStreamInfo: RTSP/RTP re-streaming timeout.

:mad:ERROR server comment 2013-10-25 13:03:05 - - - - - 3272.126 - - - - -

      • RTPSessionDescriptionDataProviderBasicRTSPWorker.processResponse: CSeq less than zero

Our stream is produced by the following syntaxes, none of them work:

udp://@<multicast_ip>:<multicast_port> --sout=‘#transcode{vcodec=mp2v,venc=x264{keyint=60,profile=high,level=3.2,nocabac},scale=0,vb=2000,fps=23,width=854,height=480,deinterlace,acodec=mpga,ab=128,channels=2,samplerate=44100}:rtp{mux=ts,dst=<transcoder_ip>,port=<transcoder_port>,sdp=rtsp://<transcoder_ip>:<transcoder_port>/<channel_name>.sdp}’

udp://@<multicast_ip>:<multicast_port> --sout=‘#transcode{vcodec=h264,venc=x264{keyint=60,profile=high,level=3.2,nocabac},scale=0,vb=2000,fps=23,width=854,height=480,deinterlace,acodec=mpga,ab=128,channels=2,samplerate=44100}:rtp{mux=ts,dst=<transcoder_ip>,port=<transcoder_port>,sdp=rtsp://<transcoder_ip>:<transcoder_port>/<channel_name>.sdp}’

Question: What could be wrong? Should this feeding format work somehow?

Thank you.
