How to re-stream an unprotected stream from FMS or a CDN such as Akamai
[wowzathreadtoarticleredirect]41[/wowzathreadtoarticleredirect]
No, we currently do not have a way to support query parameters through the live stream repeater process. I believe they will get stripped off. We may look at this in a future release but at this time it is not possible.

Hi,
Is there a way I could re-write my own live repeater, which supports query parameters?
The first step is to be able to subscribe to live streams from other servers. I think, in the previous versions of wowza, this was not possible. Is this possible in Wowza 2?
The second step would be to republish these streams for clients on this server. I saw support for vod streams using Stream class in Wowza 2. Can this be done for live streams?
Any ideas here?

If you are using StartupStreams.xml or the stream manager to start the streams and you don't stop the stream it will continue to run. With iPhone and Silverlight packetization we need to keep packetizing the stream. If you have some event you can queue off of to start and stop the streams then you can use the IApplicationInstance.startMediaCasterStream and IApplicationInstance.stopMediaCasterStream to trigger the start and stop using the server-side API. The trick if to find an event from which to trigger the start/stop of the stream. You can certainly write your own scheduler that does it based on time of day.

I haven't worked deep on the code but could this be used to re-stream from a FMS (in a local installation not in Akamai) ?
Edit: Yes, it's possible :)
Thanks Charlie

The Live Streaming step says
Set the Streams/StreamType property to: liverepeater-edge
but the Live Streaming (all player technologies) says
Set the Streams/StreamType property to: live
which seems to require setting up the akamai connection through the stream manager.
Is it possible to have the automatic connection to akamai and still stream to the iphone? if I just change Streams/StreamType to liverepeater-edge it says Stream not found

Hi Charlie, I need help. I want to use this method, but instead of using a single rtmp stream, I want to use two different rtmp origins. I want each one to be a different quality in a smil for iphone.
Do you think is possible (and how I do it if is)?
Thanks

You can repeat step #4 as many times as you want, creating different . stream files, and each one can be a different server + stream name or smil file.

I understand that, but how I generate the smil?
If I have quality1.stream and quality2.stream, how do I insert that into the .smil file?
I mean, for example in an standard .smil you have:
<smil>
<head>
</head>
<body>
<switch>
<video src="mp4:streamname1" system-bitrate="10480000"/>
<video src="mp4:streamname2" system-bitrate="7480000"/>
<video src="mp4:streamname3" system-bitrate="3480000"/>
</switch>
</body>
</smil>
In the streamname field should I put quality1.stream, quality2.stream ??

Thanks Richard
it looks alike for every stream I have to modify the file manually , is it any way to do that automatically ?
If you are referring to StreamManager, you can automate using /conf/StartUpStreams.xml
Richard
Richard
I'm not aware of StreamManager , is this an Akamai function
do you have more info about it ?
thanks

Is it possible to use one server to do more than one re-stream? I have one stream working with the above settings just fine but I'm trying to add another one that has a different source feed and it doesn't seem to be working. Of course I need to change the name of the stream but in the config what should be adjusted to to use a different name? Thanks for any help you can provide.

Yes, of course, you can have many streams with different sources and different names.

What do you mean by "token based streaming"?

Hi,
Akamai has a way to secure media streams. They generate "tokens" which the client needs to provide to the Akamai server whenever they need to fetch a stream.
The token is appended to the stream name & the url looks like this:
rtmp://live.flash.com/live/streamName@s24810?auth=daEd_cwcJchdCa6debDdCa_dldLc6dFcxct-blMUhc-4q-ppGWwGuNCDvOBkLci&aifp=1
Look at "auth=<token>". Will a Wowza reflector re-streaming an Akamai stream, support this functionality?
If yes, what do I need to configure?
If no, do you have any work around, even if it means extra code?

You can use /conf/StartupStreams.xml to start MediaCaster streams when the Server starts.
I think you can leave the Applicaiton.xml /StreamType "live", set the MediaCaster type to "liverepeater" in the StartupStreams.xml file, and set Application.xml /LiveStreamPacketizer = "cupertinostreamingpacketizer", and will work on IPhone.

Is there support for Akamai token based streaming on wowza reflectors, pulling streams from Akamai?
You still can't subscribe as such from server to server, and I don't think the source for livestream repeater is available to modify, but, if it helps, you can use a live stream(s) as a source for a Stream class stream. You make the "start" parameter "-2"

I have a few live streaming shows that are on at different times of the day ranging from 10 minutes to 3 hours.
I don't have any problems restreaming them from akamai to devices using the techniques described here. I'm trying to use the StartupStreams.xml but now my logs are filled with
CupertinoPacketHandler.resetStream[akamai/_definst_/akamai.stream]
LiveMediaStreamHandler.sessionClosed
LiveMediaStreamHandler.sessionClosed: reconnect: isCurrentSession:false tryConnect:true
which seems like a problem. I'd hope it was only connecting to akamai when someone was trying to get the restream rather than constantly connecting. Am I using the wrong approach for this kind of situation?

Hello, I am getting this warning:
WARN vhost comment _defaultVHost_ Bind failed, try again ([any]:1935): java.net.BindException: Address already in use
And, I cannot seem to stop the server or change to a directory
Thank you.

Thank you.
This either means Wowza is already started or another program is running and using port 1935. You might be starting the server in stand alone mode when Wowza is running as a service. If you are using putty or cmd window, control-c should get you back to a prompt.
You can open another console and run [wowza-install-dir]/bin/shutdown.sh (shutdown.bat)

I got the stream going thank you, however please see my other post as my stream is not working properly.

I am streaming on iPhone.
Very happy about it. We will be purchasing a perpetual license tomorrow, Sunday PST.
Right now we are running a Wowza Server Subscription for a single instance.
After we have the stream going in the iPhone it lasts without stopping.
But, there is an issue. The stream doesn't always stream when the address is entered into the browser. After closing the Safari browser we just get a blank screen in the browser if we try to stream again. But, after waiting some time it will work again.
We get a WARN server comment - HTTPStreamerAdopterCupertinoStreaming.onPlaylist: Application context no loaded [xxx.stream/playlist.m3u8]: _defapp_/_definst_
