I've read this topic about changing audio track inside an MP4 file : http://www.wowza.com/forums/content....tify-interface
But is it possible to load an audio track from an other file ? For example, I've a MP4 file containing the video + audio in original version (Matrix.mp4) and I would like to add as many file as language I have : Matrix_de.mp4, Matrix_fr.mp4, Matrix_es.mp4, etc...
The aim is to add or remove audio tracks very easily without re-encoding the "main" file everytime I made a change.
Thanks for your answers and sorry for my English
