MultiTrackVOD module with dash

Hi,

i’m using the DASH protocol to stream a file that combines more than one video track using this url:

/vod/definst/mp4:TTS001/1080/combined.mp4/manifest_mpm4sav_mvtime.mpd

i istalled the modile ModuleMultiTrackVOD and i tried to put in querystring the parameters

audioindex= videoindex= dataindex=

but they are not working, i Always receive the same video track.

do you have any suggestion to make it works?

thanks a lot,

valerio
