I have made an HLS playlist for a video file.FeatureSDPlaylist.m3u8.
I now want to add in additional audio track to this playlist, for example as shown here: http://support.jwplayer.com/customer/portal/articles/1761348-multiple-audio-renditions. I would prefer not to encode it all together, as oftentimes we receive a video file first -- at which point it should be encoded and available to play immediately -- but at a later time (perhaps in a month) there may be an additional audio track sent (for example, Spanish) that we want to enable.
How would this be done?
