Hi!

Tearing my hair out on this issue that I can't pinpoint the cause if anyone wise might take a look, the steam gets stopped anywhere from a couple of minutes to roughly 2 hours and I can not find any pattern as a loaded up network or such in regards to if it will work for long or not.

The setup is NextPVR version 6.1.5.231022 installed on Ubuntu 22.04, source is minisatIP with a TBS quad tuner running as a docker on the same server. Behaviour is the same regardless if the streams are to Kodi or Jellyfin as client. If I in Kodi set the streaming method to transcode it does seem to be alot more stable but that's not a viable solution right now as I don't have hardware transcoding.

That is two channels streaming so very confusing. It is impossible to diagnose this with just snippets please send the zipped full logs. These logs might help but the problem could be the source.

Martin

Hi Martin,

I'll attach the full zip here.

Thanks!

It looks like Jellyfin has added some kind of stupid crap keepalive, logging every second.

I suspect the quality though, could explain all those missed packets

If you open the minisatip web page do things look good while it is streaming.

Martin

TBH I'm not sure what to look for in minisatip that should indicate a problem, looks fine to me(?)

Started two streams and here's what it looks like in the webinterface

I would check when the problems occur to see if there are server errors, but STR looks low to me. Do you have a booster on to get that high SNR?

Martin

No booster, just straight from the cable connection in the wall. I did an experiment today, started a channel and had the stream both directly from minisatip to an VLC and through NextPVR to Jellyfin. VLC had no issues holding the stream for 8+ hours but NextPVR stopped as before, I think that this might rule out minisatip as the culprit

Sub might need to put in more logging around

Code:
2023-12-18 08:14:39.775    [ERROR][30]    Unexpected error streaming channel: System.NullReferenceException: Object reference not set to an instance of an object.

   at NShared.Utility.RollingFile.get_Length()

   at NShared.Streaming.StreamingHelper.StreamNative(ServiceResponseStream responseStream, Dictionary`2 parameters)

Does it ever happen on recordings?

If not, I am not sure if there is extra logging if you enable verbose logging and let NextPVR play (Settings then Ctrl-click the Log button) There might be a collision when the file rolls. Perhaps increase the timeout on the scrollback buffer to reduce the number of rolls.

Martin

I pretty much never use recording so I don't know of the top of my head but I've put a recording on now and we'll see

Tried with a recording this morning that was fairly long and it seems like something happened around the two hour mark (picture is just frozen) and if I try to play it in the webinterface I get transcoder exited, so yeah something seems corrupt with the recording.
