Hello Layal,

We do not support VP9 for VOD content. We have an article that shows what VOD formats and codecs we support. I have not linked to that section below.  
[https://www.wowza.com/docs/understanding-streaming-protocols-and-output-file-formats#supported-media-file-formats](https://www.wowza.com/docs/understanding-streaming-protocols-and-output-file-formats#supported-media-file-formats)

You can use our Java API to select which specific audio track and which specific subtitle track you want to use.  
[https://www.wowza.com/docs/how-to-select-audio-and-subtitle-tracks-from-a-video-on-demand-file](https://www.wowza.com/docs/how-to-select-audio-and-subtitle-tracks-from-a-video-on-demand-file)

We also have several articles that address selecting audio and subtitle tracks.

With regards to selecting different audio tracks, you can use the following module.

More on subtitle tracks can be found in the two different articles below.
