[HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ?

Added by Dimitar Maznekov over 2 years ago

I'm trying to make catchup for IPTV to have +1, +2 etc hours back timeshift for channels which are not recorded by provider.
I've made that setups

1.Mux Schedule for two channels as follow:

2.Setup Timeshift:

There are two streams, but not see any files recorded in /home/hts/timeshift/
And if I'll make that timeshift, how to setup another Mux to start it from -1h ChannelID and watch it one hour ago ?

WORKAROUND

Script file

/home/lib/catch-up/timeshift_hls.sh

#!/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 -g 60 \
-fflags +genpts -user_agent HLS_delayer -metadata service_provider="TimeShift" \
-f hls -hls_flags delete_segments -hls_time 10 -hls_list_size 360 -hls_wrap 361 \
-hls_segment_filename /timeshift/$1_%03d.ts /timeshift/$1_hls.m3u8
chmod +x /home/lib/catch-up/timeshift_hls.sh

Manual run
./timeshift_hls.sh [channel number]

Service file

/etc/systemd/system/timeshift_Nova.service

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.

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by Dimitar Maznekov over 2 years ago

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

Hi Dimitri

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by Dimitar Maznekov over 1 year ago

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by saen acro over 1 year ago

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by saen acro over 1 year ago

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

tuning on parameters is needed
6 segments of 10 min or
12 segments of 5 min or
60 segments of 1 min

input in tvh as iptv source

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

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.

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by saen acro over 1 year ago

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

with will set date in format
ch_name_stream_20181228122016.ts

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

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?

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by saen acro over 1 year ago

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.

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by Dimitar Maznekov over 1 year ago

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

Must give it a try with local created M3U8.
Thanks for the idea.

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

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: 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.

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by saen acro over 1 year ago

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

I tried different locations.

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

/volume1/TVH/

But I got always permission denied.

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by saen acro over 1 year ago

create folder for example in /tmp/hls

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

and try

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by Dimitar Maznekov over 1 year ago

Should be:

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

I think he is missing channelnumber/NUM where the NUM is number of desired channel.
Not bulletproof with channelnumber instead of channelid but it's way easy for me.

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 \

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by Dimitar Maznekov over 1 year ago

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by saen acro over 1 year ago

With experimenting things go to success ;)

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

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by Dimitar Maznekov over 1 year ago

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 ;)

RE: [HowTo] Catchup IPTV a.k.a +1 hour TV (in work) ? - Added by deganza 11 over 1 year ago

Where do I've to put this code?

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