Recording playback fast forward / skip issue

[shaokong@gmail.com]

I am running NextPVR server on the following laptop:

Processor Intel® Core™ i7-10750H CPU @ 2.60GHz  2.59 GHz
Installed RAM 16.0 GB (15.8 GB usable)
Device ID 298EFCB8-C150-48C8-8DDE-35722FC55241
Product ID 00329-00000-00003-AA781
System type 64-bit operating system, x64-based processor

Windows 10 Enterprise 22H2
wired network

npvr version: 6.1.4.230625

I played back my 2-hour recording on an Android TV Kodi NextPvr client but encountered the following issue:

Fast forward and skip worked until at around 57 mins mark, beyond that point, any fast forward or skip would return back to this 57 mins mark after playback was resumed. For example, when I forwarded to 1 hour mark, after play resumed, it resumed from 57 mins mark instead.

I tired web browser on the laptop as well. It quickly got confused and the time scale got messed up.

I also tried to play the recording .ts file directly on VLC on the laptop. Here are the strange things:
1. The start time was displayed as 00:00, but the end time was displayed as -7:22:47.
2. Using the mouse to click on the time line, all worked until 57 mins mark. After that 57 mins mark, the playback still worked (i.e., it didn't go back to 57 mins mark), but the current play time instant was always displayed as 00:00.

Seems like the recording has some timing related issue? Hope someone can help.

NextPVR will just be recording a dump of whatever came from your IPTV provider. The timing is encoded into the stream they produced.

It's not uncommon for transport streams to have clock issues, and the client doing playback is supposed to handle these situations. In the case of IPTV streams, sometimes their encoder crashes and is automatically restarted, effectively resetting the clock etc.

Maybe try playing it in nextpvr.exe and see what the reported duration is, and maybe try pressing left/right arrow keys during playback to test skipping.

For Kodi issues we need the Kodi debug logs.

The transcoding errors are bad in your web player streams though. I suspect this is part of your problem

Tried nextpvr.exe. The reported duration is: 00:00:00 - 00:45:24, not 2 hours.

If you want to put the file somewhere like OneDrive/GoogleDrive, and let me know the download link, I'll take a look. I can only fix reported duration in NextPVR. Any change of the Kodi side of things would need to be done by the Kodi team.

Regardless, it'll almost certainly just be because of some timing related stuff from your IPTV provider, like they restarted or stopped the stream part way through.

Kodi needs to have the database time and the actual time match to skip properly. Sounds like the source stopped delivering data which is not considered when the recording stops.

I've uploaded recording to google drive:

Please take a look. Thanks.

That link is not open.

Agreed. I can't download it either.
