[Bug] dash-stream: can't go past start point or back to live

[walterheisenberg]

Describe the problem

It is not possible to move to "live" or e.g. +15 min after start point of the stream without pressing "stop" and starting again.
I'm using ISA (+ iptv-simple) together with some german dash-streams. (see below)

example below (How to reproduce):
I want to move past 20:00 (actual time 21:30). this is not possible.

I started the dash stream, went back 30 min, let it play for 3,5 min and tried to went forward 30 min to "live". But the stream only went forward 26,5 min to the point, where I started the stream. Shouldn't it to to "live"? It is a (live)stream ...

So ISA should update the endpoint (live) in some way ...
Thx

Possible fix

No response

Steps to reproduce

In the stream, I can go back 2 hrs (from 20:00 to 18:00).
streamtime 18:00
actual time 20:00

If I go back 2h and watch the stream e.g. 1h30 min (at 19:30) and move forward because of advertising or end of the show, it is not possible to move to actual "live".
streamtime 19:30
actual time 21:30
I can only go to 20:00 streamtime and not past 20:00.
Kodi only goes forward to the start point of the stream (1h30 min ago) (20:00), where I moved backwards.

did not attach manifest files
i will have to find time to test
it is possible that the "inacessible” minutes are too close to the live edge,
at the moment i don't remember well anymore, it is possible that playing the stream too close to the live edge is not possible because cannot keep a fluent buffering

[walterheisenberg]

I added the manifests above

sometimes Kodi even goes back, when the stream was started, if it is not possible to go further forward (the point, the stream was started) In the example above the stream goes to 20:00, but "live" is at 21:30. Shouldn't ISA update the "live" manifest, so it knows how far you can go back and forth from "live"? e.g. every 10 s or 1 min?

Don't know if this is possible.
