For context re PlayHLS V3.  

PlayHLS V3 support HLS V7 server which has variant. The plugin tries to
select the best variant for SB player (i.e. 2 channel audio). If this is
a MPEG-4 stream with two track video & audio - the plugin will play the
audio track.

This is relevant to stream such as
https://live.rte.ie/live/a/channel3/news.isml/news.m3u8 which is a video
channel but has an audio only variant so network load can be minimised.

Mixloud live streams as HLS / fMPEg4 - so video has to be played but not
video.

A stream such below is very awkward as it as multiple languages (en, fr,
de,es) and stereo / surround option but no way to identify how many
channels until audio sample are examined (i.e should all tracks be
opened/fetched and tested to find 2 channel one)

HLS implementation is also a bit of the "wild west". This Brazilian
stream plays OK on all HLS players (e.g. ffplay) but it does not obey
HTTP header Content-Length (i.e HLS m3u8 playlist is cut off by LMS). It
used to play on LMS 7.9.2 but not now - I don't know whether stream has
changed or LMS.
