Audio only MPD cannot be converted using toM3u8

[TcT2k]

I'm trying to load an audio only MPD in video.js using http-streaming.

I've traced down the issue to the following line in the mpd-parser :

mpd-parser/src/toM3u8.js

Line 271 in c4c0418

playlists: addSegmentInfoFromSidx(videoPlaylists, sidxMapping),

master.playlists is only initialized from the videoPlaylists (which are empty on an audio only MPD). I've tried simply adding addSegmentInfoFromSidx(audioPlaylists, sidxMapping) as a quick workaround in the debugger, but that crashes the tab in chrome and triggers out of memory on firefox (after some time).
I'll try to investigate this further but would be thankful for any input regarding the issue.
