Multiple audio tracks

Wowza Streaming Engine
1

I followed this tutorial to configure Wowza Streaming Engine to receive one video stream and multiple audio streams : Use alternative audio and video tracks with Apple HLS
I did create several stream files:
main stream
{
uri: “udp://0.0.0.0:6970”,
mpegsVideoPID: “0x100”,
mpegtsAudioPID: “0x101”
}
de.stream
{
uri: “udp://0.0.0.0:6970”,
mpegsVideoPID: “0x100”,
mpegtsAudioPID: “0x102”
}
en.stream
{
uri: “udp://0.0.0.0:6970”,
mpegsVideoPID: “0x100”,
mpegtsAudioPID: “0x103”
}
The startup smile file is well connected.
There seems to be a problem with starting the various streams.
Only main.stream becomes active when I send the stream:

Hi Emmanuel,

the source stream is mpegts or SRT ? The approach you try is not possible with SRT ingest. Custom addon is required to support multilingual SRT… Forum’s branch http://community.wowza.com/c/hire-a-consultant/
is permiting to disscuss such third party solutions. You can post your topic there to get a proposal.
