Tvheadend

There is no limit to one recording.

If you're recording and TVh does not produce any output file, what can you see at Status -> Subscriptions interface page? Do you see input bitrate changing, and an output bitrate that is constantly "0" ?

Let me guess, you're recording an encrypted channel, right?

No, all my channels normal free TV, no encrypted, no HD channels

When this reoccurs, I'll check the Status -> Subscriptions

OK, it seems the same problem I'm experiencing and currently investigating. I thought this only happens with encrypted channels - might be due to the fact that I don't record much from FreeTV.

As you say, it has nothing to do with auto recordings, it happens on normal recordings as well. So the proper bug title probably should be "major issue: some recordings do not create an output file".

When it happens that no file is written, I don't see any log message with video metadata in the logs.
If the file is written, you see some message including metadata like this:

After the failed recording, it shows up in DVR -> Failed recordings with status File missing.

Can you confirm this? Do you see any error message in your log before the recording starts/should start?

I'm having recordings going missing too on 4.3.

I'm not 100% sure it's the same issue but I found a solution, at least in my case. Don't create folders using the programme name. In Kodi if you add a timer it automatically uses the programme name in the "folder" field - remove the text, and recordings go through as planned! O.o.

And having just checked my autorecs, DVR file retention period for autorecs is set to "4294967295" - conf sample here. All those affected were set via Kodi v18

Mark, thanks for your hint.

I checked it and unfortunately, this does not seem to be the problem - directory entry is empty for all (auto) recordings.

But I have a format string $t/$t... in the default dvr profile which in fact creates a subdirectory for each recording. Might that be causing the issue? If I remember correctly, that was the default, so it should work.

And the question is, why does it work most of the time, but still fails in so many cases? Until now, I have not been able to figure out what could be the condition that makes it fail. I can only see the result, no video metadata in the log, no directory created, no file written, 0 kbit output rate on stream and recording fails with "file missing".

So there's no recording because it doesn't even tune properly.

Do I see that correctly, you only have one single tuner?

I have the same issue with IPTV network. In tvheadend log there is no record. In kodi there is this log.

Barry, it seems like your Tvheadend HTSP Client in Kodi does log in with an account that does not have the required permissions to create a recording. Of cause TVh does record nothing then, and you won't even see it scheduled in the web interface.

Check your users access permissions in the DVR column.

I think the permissions are OK. Some tv shows I can record without this issue. This happened when I want to record show that is airing right now. /instant record/ When there are no EPG data instant recordings works.

When I schedule timer to record next show it starts to record right away and file is created.

OK Barry, understood. I tried to reproduce your issue here using IPTV, but no error happened.

• instant recording (from Kodi) on IPTV worked (no matter if the channel has EPG data or not)
• EPG scheduled recording (from Kodi) on IPTV worked

But it was only some tries, and the "no file problem" is also not really willingly reproducible here. If you hunt the bugs they try to hide

Probably you could use net sniffing or higher debug level on Kodi/TVh side to gain more insights.

I tried VPS with debian jessie and my config works there. I can record. It seems to be a prolem with hw? Is there a way how to delete all files? I tried apt-get purge tvheadend and install it again but still the same problem.

Barry, if it runs in a VPS, I don't think it is an issue with the hardware, because hw stuff is even more complicated inside VPS.

To me, it is much more likely it is a problem with your system environment. Did you update all packages on the system? Is it a very old and potentially broken system? Is all linking consistent?

Ways to avoid this are using a well-defined environment, e.g. a Docker or VM image, like it is on VPS.

Another way you can try is build TVheadend from source, so you're sure the binary exactly fits your package environment, which is what I always do.

Honestly I have no idea where was the problem. The HW on my tvh server was updated. I was using tv_grab_file to get EPG. I don't know whether it is related but I removed it and uploadit again. Recording is now working.

barry road:

Nice to hear it is working for you now

@s j:
I think I know your problem. Your logs show inconsistencies on serveral tables.
I've been facing the same problems some commits ago - use latest git version and that will very likely go away.

I wanted to give you another feedback.
The problem was a faulty power supply, which caused problems after several hours of operation.
After that the voltage broke down, so the receiver didn't work anymore and didn't consume power anymore.
This allowed the power supply to cool down again and after a while it worked again.
Unfortunately, the update to version 4.2 overlapped with the power supply failure.
It took me almost 4 months to find out.

Best regards
