We would need more detail to help. What do you mean it doesn’t run? What are the error/warning messagess? What is happening in Wowza? How do you have Wowza setup?
Charlie
That is correct. Port sharing does not work for different streams sharing the same port. It is for binding to the same port more than once to receive the same stream.

I have a problem getting this command line to work
vlc -vvv rtsp://81.140.146.206/mpeg4/1/media.amp --sout "#transcode{venc=x264,vcodec=x264,vb=500,scale=1,acodec=mp4a,ab=32,channels=2,samplerate=22100}:rtp{dst=127.0.0.1,sdp=http://127.0.0.1:9000/myStream.sdp}"
I can get it streaming with vlc 0.8.6i but vlc keeps loosing connection to the camera and stopping. It stops also if I just try playing back the original stream in vlc.
With vlc 0.9.6 I can playback the original stream without it stopping but vlc crashes when I try to use the command line to stream it.
Does anyone know if the command line has changed for the later versions?
Roger.
I think the problem with 0.8.6 is a firewall issue. My firewall was blocking the response from the get requests to the camera when vlc was trying to reset the timeout. Open the firewall or tunnel through http and it works.
The problem with 0.9.6 is a documented bug with that version where x264 encoding is broken.
I work ok with VLC in the Windows using the “vlc -vvv …” command .
Later I install the VLC to the linux, but I only could run VLC on the Xwindow GUI to play various video files, if I input the below command in text mode:
vlc -vvv /tmp/Extremists.m4v --sout "#transcode{venc=x264,vcodec=x264,vb=500,scale=1,acodec=mp4a,ab=32,channels=2,samplerate=22100}:rtp{dst=127.0.0.1,sdp=file:///$WMSCONFIG_HOME/content/Extremists.sdp}"
will get the message as follows:

What dose it mean ?
I think you can set between 0 and 1. Default value is 0.1, reading here:
http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/net/NetStream.html#bufferTime
I think that Wowza takes the sdp stream and makes it available to many clients, but there is only one stream coming from VLC, and if you are playing it then Wowza will not get it and be able to stream it through to clients.
Richard
Are you using an ElasticIP? I think I got that exact error with ElasticIP, fixed it by using the whole public DNS.
Richard
Did you allow ports 50000 and 50001 in your EC2 default security group?
Richard
Great!, you’re welcome, glad to have helped.
Richard
Wowza can handle many streams, you don’t need another instance on the same machine.
Richard
Just give each one a unique name, vlc1.sdp, vlc2.sdp, etc.
Richard
Is this two instances of VLC on the same machine? Are there two cameras?
Richard
The first post of this thread is the VLC guide, and for that use case. What part is not working for you?
Flash Media Live Encoder, Quicktime Broadcaster and Wirecast are each much easier then VLC.
Richard
On my home router I forward ports from internet to source of rtsp stream, in my case an axis cam. Then I use the public IP of my router to access the stream from anywhere else.
Richard
Take a look at the Troubleshooting Live Streaming Issues post:
http://community.wowza.com/t/-/57
Richard
I don’t. VLC has a reputation for being difficult. I don’t think it is a Wowza issue.
Richard
Probably Wirecast is the best option, with mac and pc versions and many nice tv station features.
Quicktime Broadcaster is free, but mac only, good quality but basic, no tv station features.
fastvdo smartcapture pro is interesting, a hardware solution, plugs into usb with the form factor of a thumb drive, connects to analog devices.
Richard
Can you explain in more detail what you are doing now?
Richard
