That ffmpeg things are put in .sh script which you must run in autostartup manner.
I thought there was pre- and post-mux way to start it but not so sure....
BTW you miss something cause you dont have input data stream.

instead of %d use %Y%m%d%H%M%S

Some clarifications:
To use indexing like %Y%m%d%H%M%S you must have option in ffmpeg line -strftime 1
BUT in meaning of goal is UNACCEPTABLE because created .ts chunks are NOT overwriten from newer chunks so you will become very quickly out-of-space.
So it's fine to use %03d and newer files will overwrite older.

FFMpeg self-clean chunks out of playlist file

need more set for variables

Ummm, not actualy:

#!/bin/bash
/usr/bin/ffmpeg -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2 -y -nostdin \
-hide_banner -loglevel fatal \

-segment_list /home/lib/catch-up/$1+1.m3u8 \
-segment_format mpegts /home/lib/catch-up/ch_$1_%d.ts

That's overwrite older .ts chunks. Tested with 60x1s, now I'm testing with 60x60(1h)

And add according service file

/etc/systemd/system/timeshift_Nova.service

[Unit]
Description=Timeshift Nova TV
After=tvheadend.service

[Service]
#Type = forking
ExecStart=/home/lib/catch-up/timeshift_ts.sh 103 &

[Install]
WantedBy=default.target

$ sudo systemctl daemon-reload
$ sudo systemctl enable timeshift_Nova.service # to enable startup exec
$ sudo systemctl start timeshift_Nova.service

Lets put this as new project in GITHUB

it shod

-hls_flags delete_segments

hls_delete_threshold size
   Set the number of unreferenced segments to keep on disk before hls_flags delete_segments deletes them. Increase this to allow continue clients to download segments which were recently referenced in the playlist. Default value is 1, meaning segments older than hls_list_size+1 will be deleted.

hls_ts_options options_list
   Set output format options using a :-separated list of key=value parameters. Values containing : special characters must be escaped.

hls_wrap wrap
   This is a deprecated option, you can use hls_list_size and hls_flags delete_segments instead it
   This option is useful to avoid to fill the disk with many segment files, and limits the maximum number of segment files written to disk to wrap.

HLS chunks will test later today ;)
Oh you meant it should delete old chunks.... nope, that's separate options in FFMPEG "-f segment" instead of HLS. Anyway will test that way (which is new for me but looks more easier)

So dear fellows, thanks to the ideas and help of Sean Sean acro can say - HLS chunks, even the same stream format (MPETS) are much easier and better than segments in FFMPEG. Litle cons are missing direct way to setup file name templates. They're derivatives of playlist name but anyway that's not so important. Just the name of playlist put in mux.
Here you are:

#!/bin/bash.
/usr/bin/ffmpeg -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2 -y -nostdin \
-hide_banner -loglevel fatal \
-i http://127.0.0.1:9981/stream/channelnumber/$1 \
-vcodec copy -acodec copy -scodec copy \
-fflags +genpts -user_agent HLS_delayer \
-hls_flags delete_segments -hls_time 10 -hls_list_size 360 /home/lib/catch-up/hls_$1_.m3u8

The script and the service file could be made the same way as https://tvheadend.org/projects/tvheadend/activity?from=2019-01-04

Now I'm testing full lenght 1h timeshift and after that will update Topic with that workaround.
Thanks again to anyone who helped with ideas, know how and whit push

PS:Just put it here MUX format but need testing

pipe:///usr/bin/ffmpeg -live_start_index -99999 -i /home/lib/catch-up/hls_407_.m3u8 -c copy -f mpegts pipe:1

Missing is

pipe:///usr/bin/ffmpeg \
    -live_start_index -99999 \
    -i /home/lib/catch-up/hls_407_.m3u8 \
    -c copy \
    -f mpegts \
    -metadata service_provider="Some provider" \
    -metadata service_name="Channel +1" \
    -loglevel fatal \
    pipe:1

this will solve Service01 name and provider for tag and spam in log

Nice, what can I do w/o cheks from you

There maby more optimisations with can be done.
Any responses are welcome.

Just to explain to more beginners, that value $1
is used this way

./hls_catchup_stream.sh [channel number]

If any one have suggestions
https://github.com/Saentist/HLS-TV-channel-delay

after learning some basics about linux and ffmpeg I was able to implement this script.

But now I've another problem: how do I combine that whith the epg?
The script produces the .ts segments and then I read the $1_hls.m3u8 url as new iptv-network.

When I combine this new network with the epg I'm able to view the channel from the hls.m3u8 but
I'm not able to rewind back to the previous shows.

This is the code that I'm using and in the image in the attachement channel number 4 is my catch up channel.

#!/bin/bash
/usr/bin/ffmpeg -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2 -y -nostdin \
-hide_banner -loglevel fatal \
-i http://127.0.0.1:9981/stream/channelnumber/$1 \

-metadata service_name="TeleZuri" \
-f hls -hls_flags delete_segments \
-hls_time 10 \
-hls_list_size 360 \
-hls_wrap 361 \
-hls_segment_filename /home/hts/timeshift/$1_%03d.ts /home/hts/timeshift/$1_hls.m3u8

metadata service_name="TeleZuri +1" 

dvb inputs > netwotk add ofset

Just to add few more tips and tricks about Timeshift service according restart TimeShift service when resart TVHeadend service:

[Unit]
Description=Timeshift Nova TV
After=tvheadend.service
PartOf=tvheadend.service
Restart=always

[Service]
ExecStartPre=/bin/mkdir -p /disk2/timeshift/
ExecStart=/home/lib/catch-up/timeshift_hls.sh 103 &
ExecStop=/bin/rm -rf /disk2/timeshift

[Install]
WantedBy=default.target

ok I did the following:

- I changed the following in the hls script: metadata service_name="TeleZuri +1".
- channels "Reuse EPG from"

I don't know how to add the offset.
When I load the catchup channel, do I've to merge the two channels when I map the service?

merging is not good idea.

I did it not merge but it's not working anyway.
I've the saved ts-files from the hls-script but it does not rewind...

This is not timeshift, cannot be used to move back forward time is fixed.

But how do I play a show from 1 hour ago?

I've the channel Nr 1004 which is used in the hls script and the channel Nr 4 which is the catchup channel.
Now when I'm in Kodi for example how do I recall older shows? (I'm using the TVH-Plugin who works very well)
The files are saved in the Timeshift directory but how to combine them with the epg?

Should I change the storage path in Timeshift and use the one in the hls-script?

Just use (already mapped) 1004 channel as usual channel. You will watch a hour ago your channel 4. Can pause/play and that's all.
If you setup your MUX in new network for exmpl TimeShift, in setup of that network you could set -1h. If you in CET zone UTC will be -1 so a hour ago you have to setup as UTC-2. And re-use in setup channel 1004 EPG data for 4 channel.

ok, maybe it's not the same understanding that I had about catch up tv.

What about to use the Autorec function in TVH?
Is there a way to record every show of a channel for the last day?
I mean not to record just the whole day but one sho at the time from the epg?
