I've been searching for a while now, but haven't had any success, so I thought I'd try my luck here. What I'd like to know is, if there is any way for Wowza to mux a video and audio file on demand. I have some content that is made up of a video file, and multiple separate audio files (for different languages).
I use JWPlayer for my desktop users, which has a plugin that can mux these files on demand, based on which audio track the user requests. I want to offer this same functionality to my iOS users. So in short: can Wowza mux these files for me? If yes, how would I do this?
I think Richard's suggestion also relies on all of the tracks being inside the same stream/file. I am not aware of Wowza muxing streams on the fly.
You should be able to write a batch script for mp4box and/or ffmpeg to easily mux them. If the files are currently in the proper formats, you shouldn't need any transcoding, and the process should go very quickly. If you let me know what platform you're on, I could give you some pointers on batch scripting these.
