How to publish and play a live stream (RTMP or RSTP/RTP based encoder)

[Deckard]

is it possible to broadcast only one high quality video, and transcode it t a lower quality at the server?

With FMLE, I guess you can :
- set 2 profiles, 1 high and 1 low,
- name the stream "livestream%i" (ie "livestream1" for high, "livestream2" for low),
- build a recording module on server side to record "livestream2".

Richard, am I wrong ?

You're right, but mustihi83 wants to do it on the server so he doesn't have multiple streams which he doesn't have the upstream bandwidth to handle.

Maybe xuggler then ?

Note: Wowza Server can output AAC audio using two different packetization methods; mpeg4-generic and mp4a-latm (3gpp). The default packetization method is mpeg4-generic. To switch to mp4a-latm (3gpp) add the following property to the RTP/Properties container in [install-dir]/live/Application.xml (be sure to get the correct Properties container - there are several in Application.xml):

Question 1. Does this mean that FMLE3 can connect to Wowza with h264 video and mp3 audio and the server will change the audio to AAC on the fly?
This would make the MainConcept AAC plugin not worth buying.

Question 2. After I add this property value to the Application.xml file can I upload the new file via my ftp client while the instance is running? If so, do I refresh/reboot the instance so that the changes will take effect?
I finally got this instance working and I really don't want to shut it down

No, Wowza doesn't do any kind of transcoding.

You should be able to stop and start your Wowza Server without worry, but you don't necessarily have to stop Wowza for changes to Application.xml. You can wait a few seconds, or use JConsole to unload.

thanks, it seems to be what I am looking for. Do you have any experience with it?

Not really There was a thread about this but I couldn't find it anymore ...

----For RTSP streaming to mobile devices, based on the information below, does the opening of UDP Ports 6970-9999 need to be done on the device only? Also, do UDP ports need to be open on the Wowza Server or are they already open and used if the server binds to the static ip address and uses port 554.

[*]To play using RTSP/RTP player or device:

Enter the following URL into the RTSP/RTP player:

rtsp://[wowza-address]:1935/live/myStream.sdp

Note: [wowza-address] is the IP address or domain name of the server running Wowza Server.

Note: To stream to RTSP/RTP be sure UDP ports 6970-9999 are open.

I am not sure I really understand this. I don't think Highwinds can publish a stream using a .sdp file. I really don't understand the flow of the stream. Pulling a stream from Highwinds is most likely similar to this tutorial:

appears latency in rtp - rtmp through wowza 1.7.0 or wowza version 2 is approx 3 seconds.
