Dear Mitko,
In near feature, when HLS is adopted in project, all this will work as you expect
For now start to play channel, set on pause, go to WC, take drink and continue to watch, nothing more.

Dear Saen that's mean "On-demand" doesn't work actually ?
Is it than in roadmap feature as Catchup channels ...

Hi Dimitri

Did you find a solution for your catch up problem.
I would also be interested in such a solution.

Nope, I thought there isn't way to make it. Keep wait to adopt new features in development tree...

Do you know if there is such a feature in development?

It can be done with FFMPEG delay can be set etc.

ex
TVH ch1 > ffmpeg > HLS segmenting > storage
Storage > ffmpeg tsstream > TVH ch1 +1h

delay control is harder part, second instance of ffmpeg need to be started later

maby something as this project
https://github.com/voc/hls-relive

EPG is other problem in this case

Thanks for the hint but could you give me a concrete example?

ffmpeg -i "http://127.0.0.1:9981/stream" -acodec copy -vcodec copy -f segment -segment_time 1 -segment_list_flags live -segment_list_size 60 -segment_wrap 0 -segment_list /storage/hls/catchup-1h/playlist.m3u8  -segment_format mpegts segment_%05d.ts

input in tvh as iptv source

then
https://forum.videohelp.com/threads/371484-Optimizing-m3u8-streaming-with-ffmpeg

Thank you again!

At the moment I've the following IPTV source:
file:///usr/local/tvheadend/var/tv_sender_tvh.m3u

Now where I've to put this playlist link? In this part:

-segment_list /storage/hls/catchup-1h/playlist.m3u8

or at the beginning after the ffmpeg command?
And can I overvrite the actuel iptv source or do I've to set up a new IPTV source?

Sorry for the lot of questions. I'm quite new with TVH.

This is a location where ffmpeg will create and store .m3u8 index and .ts chunks
normally this is somewhere in http served folders
/if you dont want to use apache tons of settings etc use THTTPD or some of other acme http servers /

finally you can read it by
http://localhost.or.ip:port/path/playlist.m3u8

p.s.
ffmpeg clean older files out of m3u8 index file
to be more easy to be understand replace in upper command naming of chunks to

ch_name_stream_%Y%m%d%H%M%S.ts

ch_name_stream_20181228122016.ts

read this
https://ffmpeg.org/ffmpeg-formats.html#hls-2
http://hlsbook.net/segmenting-video-with-ffmpeg/

thank you again!
As I'm a completely newby, do I've to write a script for this?
Where do I've to save the script?
Are there some good tutorials or introduction books?

start can be done by scheduled task, where to put commands.

Keep in mind that if by some reason process die it will not start automatically,
also will start recording on clean.

That's could work, but it's pritty "outside" of the tvhbox. Same way could be setup VLC to save stream and to be played after. But not as MUX Channel+1, Channel2+1 or Channel+2 etc.
For me that isn't TVH style resolution.

Edit: BTW it's posible to setup M3Us like channel muxes as:

pipe:///usr/bin/ffmpeg -i <M3U8 URL HERE> -c copy -f mpegts pipe:1

There is no other FREE solution for now.

https://github.com/mediadata/hbbts
same solution via Cesbo ASTRA

I've tried to implement the following code

ffmpeg -i "http://127.0.0.1:9981/stream" -acodec copy -vcodec copy -f segment -segment_time 1 -segment_list_flags live -segment_list_size 60 -segment_wrap 0 -segment_list /storage/hls/catchup-1h/playlist.m3u8 -segment_format mpegts segment_%05d.ts

I've tried different storage paths but I get always permission errors:

2019-01-03 16:18:10.765 spawn: [segment 0x112f720] Opening 'segment_00000.ts' for writing
2019-01-03 16:18:10.765 spawn: [segment 0x112f720] Failed to open segment 'segment_00000.ts'
2019-01-03 16:18:10.765 spawn: Could not write header for output file #0 (incorrect codec parameters ?): Permission denied

But what about redording a timer for every channel? Would it be possible to combine the recorded channel in the same epg-guide of the live-channel?
Or maybe just to combine the redorded channel with the epg guide?

In switzerland every tv-provider has catch up tv of the last 7 days. They call "catch up" as "replay tv".
And I'm wondering how they do it.

Is location "/storage/hls/catchup-1h/" exist,
and is it have permission to be writable?

I tried different locations.

for example the same location where are also my TVH recordings:

/volume1/TVH/

But I got always permission denied.

create folder for example in /tmp/hls

# mkdir -p -m 0777 / /tmp/hls

same issue. I thik that it has to do with the codec parameters.

this work on my PC

Should be:

ffmpeg -loglevel fatal -thread_queue_size 512 -i http://127.0.0.1:9981/stream/channelnumber/NUM .....

Ouch, that was so obviouse ....I didn't catch the mistake - missing %d in .ts file
Thats works for me

/usr/bin/ffmpeg -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2 -y -nostdin \
-i http://127.0.0.1:9981/stream/channelnumber/101 \
-vcodec copy -acodec copy -scodec copy \
-f segment -segment_list_type m3u8 -segment_list_flags +live -segment_wrap 60 \
-segment_list /home/lib/catch-up/101+1.m3u8 \
-segment_format mpegts /home/lib/catch-up/ch_101_stream_%d.ts

And proper script for 60 segments x60sek:

#!/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/101 \
-vcodec copy -acodec copy -scodec copy \
-f segment -segment_list_type m3u8 -segment_time 60 -segment_list_flags +live -segment_wrap 60 \
-segment_list /home/lib/catch-up/101+1.m3u8 \
-segment_format mpegts /home/lib/catch-up/ch_101_stream_%d.ts

With experimenting things go to success

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

Yeah, but there was another magic with date and %Y%m%d%H%M%S which I'm too lazy to remember... so %d is acceptable for me

Where do I've to put this code?

- in the Networks section as new IPTV-Network?
- in the Muxer-Section?
