 certainly a personal decision.

 Im sorry, i dont know what to say to that. If this is not a bug
 (somewhere) then its my env in the end and i wouldn't wont to bother
 anyone with those.

 > The second question is of course why you believe that the handling of
 input streams with "missing" audio (see also ticket #4674) is related to
 the buffering of hls...

 I don't believe what i don't even know about, sorry.  I'm reporting this
 with my very limited undertanding of video/audio codecs as just an addon
 developer for kodi who was told by kodi devs to report my findings here.
 Originally did think that this could be buffering/streaming issue but if
 the .ts file is on local filesystem, i still get the same issue.

 Does that give an answer?

 PS. im currently building ffmpeg master on (on the device where my
 original issue was first noticed) and i will report back the findings with
 debug loglevel. anything else i should provide or just close the ticket?
