Thread: Transcode a transcoded stream with Wowza 4.2

  1. #1

    Default Transcode a transcoded stream with Wowza 4.2

    Hello,

    I'd like to know if there is a way to transcode a transcoded stream. I explain :

    I have a stream provided by playlist with custom application (created with Wowza API) which named "_stream" which encode a stream named "_base" and the transcoder template is named "_stream" (with name matching enabled). I put some overlays on the stream "_base" and I'd like to transcode it to be able to have multirate streams (for example "web"), the transcoder template is named "_base". So 2 transcoder instances (with Wowza 4.2 Monthly Licence it is now unlimited).

    But I have a problem : I can play "_stream" and "_base" but not "web" (the log show nothing about "_base" transcoding, "_stream" has log for transcoding)... Why "_base" transcoder instance not launch ??? Must it be launched only after next one ?

    Here is the log of launch process :

    Default

    Hi
    That won't work if it's in the same application, otherwise you could potentially loop transcodes over and over with a non-restrictive template.

    I'd suggest you duplicate the newly transcoded _base stream to another application using ModuleDuplicateStreams. and configure the other application with transcoder as well, so that it uses the _base, or similar, template.

    Daren

    Hello,
    Ah ok. Got it. Will the other transcoder instance have access to the streams of my main app transcoder instance ? What must I be careful of ?
    Thanks.
    Best regards.

    Hello,

    I did some tests with ModuleDuplicateStreams, it works, but it looks like it need a lot of CPU resources...
    My goal was to put some overlays in "_base" stream (including OverlayImage, which is CPU only) from "_stream" (the playlist) and then put some transcoder templates for multiple bitrate.

    My overlays are changing in my main app and for one of the templates in aux app (which have duplicated stream) need to show or not only one overlay image. How can I ask in the aux app the value of a main app variable ??? Didn't understand well objects sharing between 2 app...

    It could be more easy to be able to transcode several streams in one app !!!

    Thanks a lot.

    Best regards.
