TVH hangs after 10 minutes

Hi,

I have an Rpi4 running on the latest LibreELEC (LE) 10.0.1 and tvheadend server 4.3.1979

I recorded a video, yesterday evening, and it all went well till I decided to start watching it (while it was still being recorded).

This is how it went:

Recording started at 21:30 and should have finished at 00:30

Mar 09 21:09:30 LibreELEC tvheadend[9167]: dvr: "CLV-2022-03-09-21:10" on "Rai 3 HD" recorder starting

At 22:10 or so I ssh'ed to LE and a few minutes later I also connected to the web interface of TVH and there were no issues at all.

At 22:44 I decided to play the video, so I sat in front on my TV, went to the LiveTV section of my Kodi (instlled in LE), went to recordings, and played the file.

2022-03-09 22:44:14.748 T:817 INFO <general>: VideoPlayer::OpenFile: pvr://recordings/tv/active/CLV-2022-03-09-21_10/CLV-2022-03-09-21%3a10 (1969), TV%20(Rai%203%20HD), 20220309_201000, 1367281094.pvr

Note that at that time I don't see any message from TVH, just the below, that is before I play the video (I was expecting to see the hello message from the TVH server):

It all went well until 22:59, when all of a sudden the video froze and I lost all kind of connections (connection to TVH and connection to the WiFi)
There is a connection from the client to the server about one minute before everything crashed (I don't understand why, since I was watching the video since 22:43)

So it looks like there was a connection and then kind of another one that made the entire system hang.

WiFi went down for a couple of seconds

but nevertheless, I couldn't SSH LE anymore, and also NFS connection went down (I save the videos to my NAS) - note that I could access my NAS from all other systems, meaning my WiFi was perfectly working and I saved other things from other systems to that very same NAS exactly during that time

At 00.43, system crashed. I had gone to sleep so I hadn't played with LE or with TVH since 23:15, more or less.

System recovered by himself at 11:29 on the next day. My recording stopped at 23.09 (not at 00:30)

It looks clear that as soon as I try to use the TVH Player, something breaks the system and everything collapses.
Is there any extra log I can activate in order to better debug the system?

Thanks for helping!

Is same happens when play playlist in VLC?

Where are picons located, on same NFS?

RE: TVH hangs after 10 minutes - Added by Luca M almost 3 years ago

I cannot use VLC wirh LibreELEC because that package is not available.

I tried with VLC and with Kodi Player in another Kodi instance I have (on my Firestick) directly accessing the NAS, but with both I have a slight a/v OOS issue that I cannot mitigate. I don't have any synch problems with the Rpi4 and the Kodi Player, nor with VLC used on my Mac. Probably, the Firestick cannot manage interlaced video properly.

I never played with picons, so I just used the default configuration.

This morning I used TVH Player within my LE installation to play the recorded file, and about 1 minute after, I got the wifi disconnected, and again, the same issue of the player not working anymore.

RE: TVH hangs after 10 minutes - Added by saen acro almost 3 years ago

VLC can be used on Any PC you have or even smart phone/tablet.
Your defalt config need to be costumised,
Becouse this error 404 is come from requsest of channel logo/picons.
