Thread: Wowza multiple Live audio with video streaming.

  1. #1

    Post Wowza multiple Live audio with video streaming.

    Dear Wowza team,

    We are going to cover a live event. We have arranged a Axis camera [Q6035-e-PTZ], which will provide us HD H.264 video feed. Now we will have three different audio feed coming in different language.

    We want to combine each audio feed with same video feed and have 3 output as Live Video||Live Audio 1, Live Video||Live Audio 2,Live Video||Live Audio 3.

    Can we create some kind of setup like this wowza server.

    Please let me know the possibility of combining it with 3rd software or with wowza.


    Thanks

    Hi
    This is possible with a Wowza server and some custom coding.

    If you require the custom coding to be done by a consultant, email support@wowza.com requesting the independent consultant list.
    Be sure to contact more that one consultant for a quote

    There is no facility in Wowza for muxing these streams. FFmpeg comes to the top of search for "how to mux several audio streams and one video", for example:

    http://cfc.kizzx2.com/index.php/muxi...o-with-ffmpeg/

    The input and output are files in the example, but I suppose it should be able to handle live input. Here is how to do live mpegts out

    Then you can use this technique for track selection to playback:

    Default Multiple streaming.

    Thanks for support, but i have managed to get the required stream with multiple audio with single video stream using 3 different software.

    Richard , i want to buy Amazon EC2 server for 10 days with pay per use license $5 + WOWZA 3,

    Actually i want to know the total approx. amount that we have to pay to amazon, i would like to describe my requirement.

    We have two live camera input directed to wowza server , as CAM1 and CAM2.

    CAM1+ CAM2 Spec: 320x240 @25fps , 320kbps [272kbps + 48kbps] , H.264, Baseline 3.0 , key frame = 2 sec.

    Then we have three more input feed coming to wowza server after mixing with three different Audio.

    Feed1 + Feed2 + Feed3 [Specs] = 320x240 @25fps , 256kbps [224kbps + 32kbps] , H.264, Baseline 3.0 , key frame = 2 sec.

    So we have total of 5 feeds.

    Could u please let me know how to calculate the data usage and its price?

    Check the Amazon Pricing page for details.

    Bandwidth is free going into you Wowza EC2 server. You'll want to figure out your maximum # of client streams you want to support, and then figure out the total size of GB transferred this will be. That will be what you need to figure your bandwidth costs. Then there are the other costs, such as upfront free, and hourly rates.

    From Wowza, it is just $5/day for the daily license.

    Hi
    If Ajitpals doesn't reply with how this was done and what software was used (before you run out of time), as I mentioned above this can be done with a custom module in Wowza.
    Requirements :
    You'll need a sound card with multiple inputs or multiple sound cards.

    Hi
    You could build a custom module yourself or a consultant will build it for you if you choose a consultant to take on this task.

    If you require the custom coding to be done by a consultant, email support@wowza.com requesting the independent consultant list.

    I investigated this deeply and ended finding a solution that is basically free and very easy without a component or anything fancy.

    Setup a ffmpeg job on your server, the ffmpeg job should probably be per language you want to support.

    The syntax is:




    ffmpeg -itsoffset -5 -i "rtmp://127.0.0.1/live/StreamA.sdp live=1" -i "rtmp://127.0.0.1/live/StreamB.sdp live=1" -vcodec copy -acodec copy -shortest -f flv -map 0:0 -map 1:0 rtmp://127.0.0.1/live/StreamC.sdp


    In my case I am using Wirecast for the first video+audio broadcast (StreamA.sdp) and flash media live encoder for StreamB which is just the translators voice.

    The result of this is a new stream, StreamC which has the video of StreamA + the Audio of StreamB. the itsoffset is a parameter you can play with to give your translator some delay.
