Timeshift questions

Nikola Vitanović

Hi all,

I'm new here and I plan on using TVHeadend for receiving DVB-T2.
The thing that interests me the most is timeshift feature, but It's not mentioned in documentation that much.

As far as I understand timeshift allows you to pause live TV and forward/rewind it. My Question is is it possible for TVHeadend to keep 2 hours of specified channels so I can rewind them while watching live TV via Kodi for example?

I want to be able to rewind specified/all channels up to 2 hours. For example I start watching TV and see that I missed some TV show, and then I rewind it and watch from that moment. After the TV show is over I would like to forward to some other TV show that started already.

Is this possible to achieve with TVHeadend or do I need some additional software?

Also do I need multiple DVB-T2 receivers (one for every channel or only one per multiplex)?

Thanks in advance!

The timeshift function doesn't do this, it's per subscription not channel. You can however set it up to rewind up to 2 hours of active channel/subscription. Also, timeshift only works via HTSP & not HTTP.

I suppose you could do what you want by using timers & play that back if you miss anything. However you'd manually have to delete the recordings or setup a dvr profile that deletes them after 24 hours.

Per mux.

So does anyone have an idea how should I start implementing this kind of timeshift. So the user can always rewind the channel/multiplex up to few hours?
I've seen some DVR settings, can I map a recording as a channel on TVHeadend?

So I've managed to achieve this by setting the scheduled DVR recording and it works fairly well. The problem is now I don't know how to add a channel from local file system.

Recording is in /home/hts/TV/channel.ts

I want to add that as an IPTV channel. I tried pipe:///home/hts/TV/channel.ts but that does not work. Should I host a local server that will serve the .ts files?

Thanks!

Try using file instead of pipe.

Hello Nikola,

There is a feature request that you could start implementing: https://tvheadend.org/issues/3991

This will be great, I really miss this features that in other PVR as MythTV works.

I am not programer, but if you need some help just ask for it.

Kind regards.

I've tried using file but I always get:

2017-03-07 11:39:50.000 iptv: KCN IP in local_IPTV - unsupported scheme [file]

This is the pipe way:

pipe:///usr/bin/ffmpeg -loglevel fatal -i /home/hts/TV/BelleAmie.ts -ss 00:20:00 -codec copy -bsf:v h264_mp4toannexb,dump_extra -metadata service_provider=PROVIDER -metadata service_name=TEST -tune zerolatency -f mpegts pipe:1

The problem with this implementation is thatDVR records the channels and I'm able to view them via Kodi as Recordings and also to watch them realtime or rewind/forward/pause while they are still recorded, and this is the thing I want to achieve.But If I add it as a channel then I can't rewind, how can I achieve this? I tried those streams with Kodi and VLC and I can't rewind. I'm just curios why are the recordings treated this way (which works good with rewinding/pausing/playing), but as soon as you set it as a channel you can't rewind/forward/pause?

Thanks!
