Hello!
So I've been having this problem with Kodi when I watch online TV streams with Retrospect. At some points during a stream, apparently randomly but almost always at least once during a 30-min episode, the playback freezes, apparently to buffer. Now, a little buffering isn't something that would annoy me all that much if it wasn't for the fact that when resuming, the video skips ahead the same amount of time that Kodi spent buffering. It simply skips part of the show. Which is incredibly annoying.
When this happened, these messages appeared in the logfile. The stream froze at 18:40:12 for a few seconds before skipping ahead. (Full kodi and retrospect debug logs)
According to this thread the problem can be caused by the network, but even if so, I don't see why Kodi would skip ahead over parts of the stream.
I tried to increase the size of the cache by setting the following settings in advancedsettings.xml
but no luck. I opened the same stream (copied URI from log) in VLC and it played perfectly.
According to this thread it might have something to do with the stream format (.m3u8 HLS) being handled by ffmpeg directly and ffmpeg is the one at fault because of some bug in its libraries, but apparently it was fixed and the thread is quite old so one would think that the fix would be pulled up to by now. Is this not the case?
Any thoughts on the cause of this is appreciated, as I said it's incredibly infuriating with these intermittent skips.

According to this thread it might have something to do with the stream format (.m3u8 HLS) being handled by ffmpeg directly and ffmpeg is the one at fault because of some bug in its libraries, but apparently it was fixed and the thread is quite old so one would think that the fix would be pulled up to by now. Is this not the case?
Any thoughts on the cause of this is appreciated, as I said it's incredibly infuriating with these intermittent skips.
