Usage


To select audio, video, and data tracks, add the following query parameters to the stream URLs as required:

audioindex=<index>
videoindex=<index>
dataindex=<index>

The default value of index is 0 which uses the first track of each type. To use the second track of a track type, set that type's index to 1. To use the third track, set index to 2, and so on. Using index parameters is only required if you want to use a track other than the first track of that type (and therefore defining an index of 1 or higher).
