stream not exist redirect vod

Wowza Streaming Engine

Hi this is possible to replace a stream that not exist by a vod file?

Example:

i create a video player with this data: rtmp://127.0.0.1/live/NOSTREAMEXIST

And the wowza play a rtmp://127.0.0.1/vod/mp4:sample.mp4

Thanks for your help

The easiest solution to this would probably be to use this module to loop a video until a live stream is available:

The Stream class stream, which is named “Stream1” in the example setup, is a live stream that playback clients stream.

The source of a Stream class stream (“Stream1”) can be files or other live streams. The Stream class can switch from one file to another, and to a live stream and back to a file, etc. These are in turn the source of Stream1, but the player will continue to play Stream1.

Yes, that is true. If you use an RTMP live encoder to publish a live stream named “myStream” you can play that directly, of course. But it is not what you are wanting to do when you are wrapping that live stream in a Stream class stream to use the loop-before-live example. You want to play the Stream class stream that wraps the live stream.

Mary,

I considered some possible approaches to accomplishing that, but they all fall apart as I think them through.

For reference, the source for ModuleLoopUntilLive is included in the collection download, but I don’t think there is way to extend this to accomplish what you describe. You can have multiple loopUntilLiveSourceStreams as long as you have the same number of loopUntilLiveOutputStreams, and each the members of both lists have to be unique or you will probably have strange behavior, i.e. you can’t share the same loopUntilLiveOutputStreams for different loopUntilLiveSourceStreams

Hi rrlanham but in this site (Loop a pre-roll until a live stream starts) says that i publish to myStream and if this stream (myStream) is not live play Stream1, but if the stream myStream exist so it plays the content??

Right?

Thank’s

Ok, i will try this solution, but imagine that you have more 1 milion streamnames… This is not a viable solution do write all the streamname and create a playlist with all the streams.

This is possible to do a generic solution to map all streamame that not playing play a vod.

Like this (every stream redirect to a playlist):

	public void onConnect(IClient client, RequestFunction function,
			AMFDataList params) {
		getLogger().info("onConnect: " + client.getClientId());
		swapToPlaylist("Stream1");
	}

	public void onConnectAccept(IClient client) {
		getLogger().info("onConnectAccept: " + client.getClientId());
		getLogger().info("onConnectAccept: " + client.getClientId());
		swapToPlaylist("Stream1");
		
	}

or this:

<smil>
    <head>
    </head>
    <body>
        <stream name="*All streams  who are not playing "></stream>

        <playlist name="pl1" playOnStream="Stream1" repeat="true" scheduled="2013-09-25 16:30:00">
            <video src="mp4:sample.mp4" start="0" length="-1"/>
        </playlist>

    </body>
</smil>

If you have configure the application correctly, while there is no live stream being published, “Stream1” will play sample.mp4, then when you publish a live stream, you will publish to “Stream1” and the live stream will override sample.mp4.

There is no stream named “mary”
