Hello Community!

We have a project with 16 different interpreters. A Video with 8 different audio channels (stereo) will be streamed to the Wowza Streaming Engine. The 8 different audio channels have 16 different audio mono channels. Each of this 16 audio mono channels are one language.

What I have done before:

1.) I have created 2 different applications (one for the left-channels and one for the right-channels).

2.) Then I have created 2 Transcoder Templates (one for the left-channels and one for the right-channels) and set the Fallback Template of each Transcoder in each application (left and right).

**The templates are (for now) audio-only!**

**Important: I have used this community article:** [http://community.wowza.com/community/questions/1943/transcode-audioleftright-channels-to-two-mono-stre.html](http://community.wowza.com/community/questions/1943/transcode-audioleftright-channels-to-two-mono-stre.html)

3.) I also created similar stream-files to test it and it works perfectly. It splits each stereo channel (8), into 16 different channels.

**Info: Each stream-file have the right audioPID configured (audioPIDs from 250 to 257 = 8 channels)**

**The source stream is a MPEG-Stream and we want to transcode this stream to a final Apple HLS Stream with 3 to 4 different video formats (720p, 360p etc.) and 16 different languages.**

**Now our question is how can we realize that?**

**Is it possible to combine the 16 transcoded audio-streams with the different video formats and make an Apple HLS Stream out of it?**

**My approach is to create a SMIL or Startup-File. Have you any advice for me?**

**Can somebody help me?**

Thanks a lot

Rob
