TVHeadend always crashes - can't enter web-if anymore

suwofis

Hey as the title says tvheadend always crahes in Linux after I added a new IPTV Network. Since then it crashes and I cannot enter the WEb-IF anymore. What can I do? I am posting you the log files.
If you need more info, please tell me. I'm thankful for your help. I have noidea what to do anymore.

Best regards

Does TVH actually crash, or does it just become unresponsive? Normally a crash will put something in the log.

I don't have any knowledge about IPTV, but your log does not seem to give any clues apart from stopping just after calling ffmpeg.

You could get some more details by enabling Debug/Trace logging. To do that, you can either try to get the WebUI running again and enable it in the Debugging page, or, you can enter some extra command line arguments when starting TVH.

To simply get rid of all of your IPTV networks and get your system running, you could move {TVH_Home}/.config/hts/input/iptv temporarily to somewhere else.

To add the Debug/Trace to your command line, have a look here:

https://docs.tvheadend.org/documentation/appendices/cli-commands#debug-options

You will need --logfile, --debug and --trace. For Debug/Trace, you could start with iptv, iptv-pcr and iptv-sub and see if they give you any clues.

./tvheadend --logfile my_log.log --debug iptv,iptv-pcr-iptv-sub --trace iptv,iptv-pcr-iptv-sub

The log file can get really big really fast, so be careful where you put it.

suwofis P.S.: The input/iptv Folder does not exist in my hts folder...

Try to find where these files are on your system. They are text files, see if you can find the number of input streams and change that value.

UPDATE: Alternately, you could also simply edit the network files so that they are disabled, get into the WebUI and then enable the ones that you want.

Thanks for your helpful reply. So if I got you right I have to hit in the console the following:
tvheadend -logfile my_log.log --debug iptv,iptv-pcr-iptv-sub --trace iptv,iptv-pcr-iptv-sub

and then systemctl start tvheadend

Just asking before I'm doing something wrong...

suwofis I have to hit in the console the following:
tvheadend -logfile my_log.log --debug iptv,iptv-pcr-iptv-sub --trace iptv,iptv-pcr-iptv-sub

and then systemctl start tvheadend

Almost, tvheadend --logfile my_log.log --debug iptv,iptv-pcr-iptv-sub --trace iptv,iptv-pcr-iptv-sub will actually run TVH from the console.

If you want to do it via systemctl you need to find the config file for TVH and then add the extra parameters there.

suwofis tvheadend -logfile my_log.log

I also noticed a typo in my original instructions, it should be --logfile not -logfile.

Ok will try it tomorrow and send the logfiles then. Thanks a lot in advance

suwofis

Ok I attached the created logfile. Starting tvheadend this way works but all my config,networks are not there as I can't use my user then and only a standard user. So no troubles.
Therefore I have to start it via systemctl for getting my admin user. But doing with systemctl it always crashes after a short time. I tried to create you a second log reporting this. Maybe it gives you some useful information.
I think the sweez_neu networks cause the problems...

Did you edit /etc/init.d/tvheadend to add the parameters?

Try looking for a line ARGS="-f" and adding the parameters there.

I also tried to play a few of the streams with VLC. Some stalled after about 5 seconds and some streams seemed to work. It could have been geoblocking.

Also: Please describe your 'crash' in a little more details. Is the TVH binary actually crashing, or does it become unresponsive? Where you you see this 'crash'? What messages do you get?

suwofis

Thanks for your help so far. Yes, some of the streams may not work in your area die to geoblocking reasons.
I think I found the mistake: The number of input streams should be Set to 1. And in These Networks I forgot to do so. Therefore ffmpeg is opened up to 15 Times per second or so which causes the crash.

So the next step to fix is the question if it's possible to change the setting for each iptv network also by not using the web-if which I can't enter anymore.
Or if the two Networks with the wrong setting can be deleted somehow.

Ok, thanks for your help again. Well it had some hard errors and all this didn't really help.
I reinstalled it. It was the easiest way. Now it works again.
Thank you for your great support.

I see you are using iptv: can you help us check if the changes from: tvheadend/tvheadend1866 will not break parsing the input for iptv?
uknunknown/tvheadendtree/dev_fix_overflow_iptv
all changes are in file: src/input/mpegts/iptv/iptv_http.c
thank you.

suwofis

ukn_unknown I would like to help you. But I'm an absolute beginner and I don't know much, just how to add the network and so on.
But maybe you can tell me exactly what I should do.
Should I post you the content of the file you mentionned above?

first step is to compile from source code.
instructions were provided for other user in https://tvheadend.org/d/8186-tvheadend-buildinstall-on-lubuntu-2004-64bit-with-igpu-8-transcoding/59
because you have to test another branch, you have to replace:
git switch dev_remove_err
with:
git switch dev_fix_overflow_iptv
let me know if you need more help.

suwofis

Well I need some more help. My tvheadend runs on an ubuntu server and to be hones I don't really understand what I can do for you.

Maybe you can give me a step by step instruction and tell me what I am doing as I am really no expert and not sure how to compile code and such things.

Step 1: how to compile TVH from source code:
https://docs.tvheadend.org/documentation/development/compiling/compiling-tvh-with-vaapi-support/for-lubuntu-24.04
Those instructions are describing also how to install LUbuntu ... you can skip those and continue from Update to latest software .
