[HLS] Issues with adverts (x-discontinuity)

[matthuisman]

Hopefully we can use this issue to finally get to the bottom of what causes pauses / stopping when playing back HLS with SSAI / adverts using x-discontinuity

"""
channel 7 works but it seems to get stuck on when an ad break starts. Similar to the issue reported for Pluto TV.

Playback paused for a few seconds at the start of every ad break. It seemed the first 2 ads were local and each had to load, then it reverted to a more generic ad stream. For the past week it used to hang with a percentage sign on screen but it would never restart itself. This was happening with 2 other people as well that I know personally which spurred me to log an issue here. It just so happened when I ran the debug log, it wasn't getting stuck for any more than a few seconds.

Info on debug file:
turned on debug, restarted kodi, went to 7flix and waited for 2 ad breaks. At the start of each ad break, it paused for around 5 seconds, It did this for the first 2 ads in each ad break. I presume it was due to those first 2 ads were local to my region which I haven't noticed before. After 2 ad breaks, I stopped stream and exited Kodi.

I've tried with "use Inputstream HLS for Live Streams" turned off in IPTV AU settings > Playback but it still occurs. It's only an issue with Channel 7 channels"

I never seem to see these issues on Windows - so maybe Android only issue??

Will anyone developing this plugin acknowledge this? This issue is beyond annoying and been going on for far too long, I can’t watch any streams that have x-discontinuity ads without them freezing the stream or outright closing the stream. I’m using Android TV.

@MajinLugia what's your expectation here? I can give you the following information:

• The issue has been acknowledged.
• There is a very small team of people actively contributing to this project (2 for a long time, more recently 3)
• The original developers are long gone
• Even with combined knowledge, there are still a lot of areas of the code base that we do not understand
• We are paid $0 per hour to work on this
• This is not the only issue

@matthuisman does this mean this playlist took 6.5 seconds to refresh?

Or am I reading IN/OUT from the wrong point of view?

[matthuisman]

GET IN called when the proxy receives the request
GET OUT called after the proxy receives a response

So I suspect their server here took 6.5 seconds to respond?
Or the proxy took ages to do its thing?
I really should log directly before the request out so we can tell
