Hi Charlie,
Thanks for reply. It seems vlc is a tricky option here, I am running vlc on my laptop so the address is 127.0.0.1. I tries using this as the vlc-ip-address but to no avail, vlc runs but doesnt say streaming and the sdp file is not created.
If using vlc to stream from laptop to wowza ec2 server is difficult what other realtime encoders/streaming would you recommend? I need something stable for the project.

đ You must be reading my mind, I setup on2 flix for free, got the streaming working in 5mins, but I am now looking at the wirecast, seems like a great product with some great features such as the realtime chroma keying etc and multiple layers.
Think it will be the way to go. Is there an IRC for wowza?

Hi All,
I tried VLC 1.01 but, I returned quickly to VLC 0.8.6i, results are far better.
I am using a live pinnacle encoding card on winXP, using the following cmdline:
âC:\Program Files\VideoLAN\VLC\vlc.exeâ -v -I rc --ttl 12 dshow:\ --dshow-vdev=âPinnacle WDM PCTV Video Captureâ --dshow-adev=âSB Audigy Audio [2300]â --volume=1500 --dshow-chroma=RV24 --sout="#transcode{venc=x264{keyint=25},vcodec=x264,croptop=16,cropbottom=16,cropleft=32,cropright=32,vb=350,fps=24,scale=1,acodec=mp4a,ab=32,channels=2,samplerate=44100}:rtp{mux=ts,dst=,port=5014,sdp=http:///live.sdp}:sout-keep"}}
Adding more â-vâ items crashes vlc after a while âš
I tested flowplayer, but the result is not good. I switched back to JWPlayer, and it works like a charm !

It would be very very useful to add a note to the main post that x264 encoding is broken in VLC 0.9.x for Win32. Consequently you have to use 0.8.6i version of VLC for RTP streaming. Fortunately the version is available for downloading from the official site.
Such a note would save me a day of endless trying with x264, h264 and VLC. But finally I got my DLink DSC 6110 IP-camera broadcasting to Internet đ

Hello,
It looks like I need some help. I successfully run DLink IP camera -\> VLC -\> Wowza -\> JW Player combination. But I faced a problem: the JW Player takes very long time to connect. I though this is the player problem, but here is the log-file:
```auto
INFO session connect 2009-02-04 18:24:28 1837704724 193.19.000.000 - 3466 3073 0.0090 - - - - - - 193.19.000.000 -

```
Note the 37 and 15 seconds pauses between the connect and play commands. Obviously nobody would wait 40 seconds and suppose that the service is broken. What may be the reason of the problem and how to resolve it? The VLC command line is as follow:
```auto
c:\program files\vlc\vlc.exe -vvv rtsp://10.195.000.000/live.sdp --sout "#transcode{venc=x264,vcodec=x264,vb=256,width=320,height=240,fps=25,noaudio}:duplicate{dst=display,dst="rtp{dst=193.19.000.000,port-video=10010,sdp=file://c:/vlc1.sdp}"}'
```
Any help would be really appreciatedâŚ

Hello Charlie,
Thank you for the rocket fast answer. This is what I was afraid of. I will look at VLC though as x264 for Win32 is broken for 0.9.x and nobody cares about is for months, I wouldnât expect too much.
The only thing is that this is 100% second connection. I even tried right now and opened 2nd browser:
```auto
INFO session connect 2009-02-04 22:54:44 176673127 80.64.000.000 - 3464 3073 0.02 - - - - - - 80.64.000.000 -

INFO server comment 2009-02-04 22:54:44 - - - - - 522895.77 - - - - - - - MediaStreamMediaCasterPlay: startPlay
INFO stream play 2009-02-04 22:55:12 176673127 80.64.000.000 - 3682 3494 27.934 vlc1.sdp 55356 0 0 - - vlc1.sdp -
```
Another 38 seconds. At this moment Wowza gets the RTP-stream for sure, so there is no time for expecting the keyframe here. Do you think this is the same issue, but between Wowza and player?
Regarding the module: I already tried it and found one interesting thing â it sees only 1 channel (vlc1.sdp) from my 6 channels (vlc2âŚvlc6.sdp). Anyway I did not found it too useful, may be I was wrong?

Yes, this is not the best choice, but I do not know any other MPEG4/RTSP -\> H264/RTP convertor. Do you know any?
Also I canât believe that itâs possible to have 20 seconds without keyframes. I even specified keyint=5,idrint=5 according with this doc: [http://wiki.videolan.org/Documentation:Streaming\_HowTo/Advanced\_Streaming\_Using\_the\_Command\_Line](http://wiki.videolan.org/Documentation:Streaming_HowTo/Advanced_Streaming_Using_the_Command_Line) . Unfortunately I canât check if the parameters work as expected.
May be I should send you the debug log, so we are sure this is 100% not Wowza issue?

The solution was found â thank you, Charlie!
```auto
transcode{venc=x264{keyint=15},vcodec=x264...}
```
With fps=10 the setting produces pretty fast response. I think it would make sense to add the note to the original post.

Hello, just new to this forum.
I am trying to setup vlc working with wowza using rtp. They are installed in the same windows host. I have read all the posts in this thread but still cannot get things working. hope you guys can give me some advice.
following the tutorial:
vlc commands(1 audio sample and 1 video sample):
vlc -vvv âc:\Downloads\BreatheMe.mp3â :sout=#rtp{dst=192.168.1.45,sdp=http://192.168.1.45:8888/test.sdp}
vlc -vvv âc:\Downloads\Extremists.flvâ :sout=#transcode{vcodec=mp4v,vb=800,scale=1,acodec=mp4a,ab=128,channels=2}:duplicate{dst=rtp{dst=192.168.1.45,mux=mp4,port=1234,port-audio=1234,port-video=1234,sdp=http://192.168.1.45:8888/test.sdp}}
192.168.1.45 is my local ip, using 127.0.0.1 is the same.
I can catch them with âvlc [http://192.168.1.45:8888/test.sdp](http://192.168.1.45:8888/test.sdp)â to play.
And in ânativertp.htmlâ, I set stream to â[http://192.168.1.45:8888/test.sdp](http://192.168.1.45:8888/test.sdp)â and click âplayâ.
From the console I can see there is no error, the last line is âINFO stream play [http://192.168.1.45:8888/test.sdp](http://192.168.1.45:8888/test.sdp) -â
However, there is nothing playing in the html page.
there are also lines like âINFO server comment - UDPTransport.bind: /192.168.1.45:50000â. I guess this is the communication between VLC & WOWZA and I try to play âudp://@192.168.1.45:5000â with VLC and it works, although the video is distorted.
I also try this vlc command:
vlc -vvv âc:\Downloads\BreatheMe.mp3â :sout=#rtp{dst=192.168.1.45,sdp=rtsp://192.168.1.45:8888/test.sdp}
I can use VLC player to catch it, but when I use ârtsp://192.168.1.45:8888/test.sdpâ as the stream in ânativertp.htmlâ, I got an error âERROR serve comment - RTPSessionDescriptionDataProviderBasicRTSPWorker.processResponse: CSeq less than zeroâ. Finally I got a â\*\*\* RTSP/RTPS re-streaming timeout.â
anyone has any idea? I gotta use vlc cuz it works in linux, which is my future goal. thanks a lot.

Hi Charlie, thanks for the quick response.
I have tried this before, the problem is whenever I use x264 or h264, vlc crashes right after launch. (using vlc 0.9.8a)
And when I try it with a mp3 and without encoding, vlc is fine, but there is not sdp file generated in that âcontentâ directory.(there is no problem with â%WMSCONFIG\_HOME%â), I can generate the sdp file to âc:\downloadsâ but not the %WMSCONFIG\_HOME%.
Even if I generate the sdp somewhere and copy it to â%WMSCONFIG\_HOME%\contentâ, and use the correct stream name, it still does not work. I tried it before.
Thanks.

hi, I just tried it again.
for once vlc generateed sdp file, but sometimes it did not.
I am sure I have used it to generate sdp file before.
Also, when I used a http url to host the sdp file, I tried to save it from
web browser and then copied it to âcontentâ directory, same problem.
Thanks.

hi Charlie,
thanks a lot, I tried to encode mp3 to AAC (becuz as I said the video encoding crashed vlc software), and it is playing.(I used âsdp=http://192.168.1.45:8888/test.sdpâ)
final command:
vlc -vvv âc:\Downloads\BreatheMe.mp3â :sout=#transcode{acodec=mp4a,ab=128,channels=2}:duplicate{dst=rtp{dst=192.168.1.45,sdp=http://192.168.1.45:8888/test.sdp}}
I have another question. In the nativertp.html, the server is ârtmp://localhost/rtpliveâ, and vlc support rtmp protocol, so how can i play it in vlc? when I tried this ârtmp://localhost/rtpliveâ directly in vlc, it was not able to open this MRL.
I wanna try in vlc so that I can use vlc to test WOWZAâs streaming in other computers easily. Thanks.

I copied âNativeRTPVideoStreamingâ folder to another computer and ran nativertp.html, revise server url and stream name, and it worked.
This should be simple enough for me to test in other computers.
Thanks for everybody posted here.

Hello, I got WowzaProForAmazonEC2 instance running.The sample video is playing fine.
Later I use VLC to generate a sdp in HTTP format like â_._._._:8888/test.sdpâ(it is valid). However, when I try nativertp.html and input correct server and stream, there is no error in the HTML, but nothing was played. in WOWZA server, I got the following log when a connection happened:
INFO stream publish http://_._._._:8888/test.sdp -

INFO server comment - RTPMediaCaster.Reconnector: stop

any idea what does this mean? Thanks a lot.

I tried VLC in a host, and WOWZA in another host in the same LAN.
VLC is running fine and output sdp file correctly. however, WOWZA still cannot bind udp port. I tried different ports in host with VLC, none worked.
and when I checked the port occupation in host with VLC, the udp ports used by VLC was not occupied. Not sure if it is the problem of this version of VLC.(0.9.8a)

Hi charlie, thanks for your reply. The error in WOWZA log is what I posted in #106, as following:
INFO stream publish http://_._._._:8888/test.sdp -
INFO server comment - UDPTransport.bind: /_._._._:50000
INFO server comment - UDPTransport.bind: /_._._._:50001
ERROR server comment - RTPUDPListener.init: java.net.BindException: Cannot assign requested address
INFO server comment - RTPMediaCaster.Reconnector: stop
ERROR server comment - RTPUDPListener.init: java.net.BindException: Cannot assign requested address
The ip address is correct and valid, including sdp file, but it is of the host running VLC. And I think WOWZA is trying to bind the port of the host running VLC but not WOWZA itself, right?

thanks your replies. sorry that I did not have time for this yesterday.
Previously it was my mistake that I used the ip of VLC as destination. I just tried EC2âs public dns(eg. [ec2-75-101-169-195.compute-1.amazonaws.com](http://ec2-75-101-169-195.compute-1.amazonaws.com)) for destination. the sdp file generated by vlc has a line like this:
âc=IN IP4 75.101.169.195â
and then I observed the same error in WOWZA log:
"INFO stream publish http://_._._._:8888/test.sdp -
INFO server comment - UDPTransport.bind: /75.101.169.195:50000
INFO server comment - UDPTransport.bind: /75.101.169.195:50001
ERROR server comment - RTPUDPListener.init: java.net.BindException: Cannot assign requested address
INFO server comment - RTPMediaCaster.Reconnector: stop
ERROR server comment - RTPUDPListener.init: java.net.BindException: Cannot assign requested address"
Then I modified sdp file, changed it to:
âc=IN IP4 [ec2-75-101-169-195.compute-1.amazonaws.com](http://ec2-75-101-169-195.compute-1.amazonaws.com)â, and uploaded it to â/contentâ folder of WOWZA
And what I saw in WOWZA log was:
"INFO stream create - -
INFO server comment - MediaStreamMediaCasterPlay: startPlay
INFO server comment - RTPMediaCaster.create
INFO server comment - RTPMediaCaster.init

Seems to me that binding is successful, but it still does not play.
Thanks a lot for your helps guys.
