Yes. And enable timeshift in your tvheadend configuration.

What is the latest beta build?

I've got Build: 3.3.521~gbc79977~quantal


RE: Timeshift Support - the_mouse - 2013-04-17

Just wondering what other peoples experiences are with live pause? I cannot seem to get it to work too well but not sure if its xbmc or TVHeadend. I am currently using the latest Beta version, Have timeshift enabled. If I click the pause button it does pause but when I resume it only plays one second then stops. When its paused the time counter keeps going so I expect that means it is caching the stream. I cant move backwards or forwards either. I have to stop playback then restart the channel to get it back. I have three PC's in the house running XBMC 12.1 and they all do the same thing. Anyone else having anything similar? Thanks

Hi Mouse, I'm having similar experience to you, yes I understand that time shift is a new beta feature but mine only seems to be good at pausing if I try to fast forward or rewind it just stalls.

And anything else you can think of (good starting point my include info about the tnuers, or better still a debug log of whatever you can get).

Thanks Adam, i filed Bug #1701

Can no one offer any suggestions? I cant really use liveTV 'pause' as its about 50% hit and miss if it is going to resume or not. Strange thing is the status page on TVHeadend shows XBMC as an active client and but the video is just frozen.

Edit : Tried some things :-

Just installed version 3.5.115 off the unstable PPA to see if it changes anything. The first channel I started watching worked perfectly, I could pause and resume without issue on the OPENElec 3.0.1 box. Changed channel and back to the old problem, plays about 1-2 secs then stops. I did notice that when resume did work for the first time, after about 3 secs of play back the picture went all pixilated and messed up, then it came right and played fine. What are the chances that XBMC cannot handle this stream error correctly and so stops playback?

Tried the ubuntu 12.10 desktop with XBMC 12.1 and it had the same issue.

I have also posted this on the TVHeadend forum hopefully Adam may be able to cast some light on this??


RE: Timeshift Support - Bernd245 - 2013-04-22

Is it possible to put the timeshift buffer to a ramdisk on the client?
HDHomeRun -> DS211 (TVHeadend) -> HTPC (OE3 with TVHEadend HTSP Client)

RE: Timeshift Support - the_mouse - 2013-04-26

Thought I had better start doing some debugging to find this. Found that it was complaining of a buffer full error but seems to be ok on the first tune after a reboot. Googled the error and found posts on the TVHeadEnd forums regarding this exact error. All I had to do is check the box Unlimited Max File Size. Worked on every channel change!!

RE: Timeshift Support - Honker - 2013-07-18

Hi,

I also have troubles with the timeshift function after resume the paused channel.

TVHeadend is running as a Debian Wheezy VM on an ESXi System and I tried the versions 3.4, 3.4.27, 3.5.231
Tried XBMC on a MacBook and a normal Ubuntu system with the versions 12.2 and 13.0 nightly builds

The TV card is a Digital Device Cine S2 Debian Wheezy system.

A few seconds after I resume the channel I can see stuttering and artifacts. The xvmc.log then shows lots of ffmpeg error messages:

Code:
ERROR: ffmpeg[1924E000]: [h264] mmco: unref short failure

21:27:20 T:4716814336   ERROR: ffmpeg[1924E000]: [h264] mmco: unref short failure

Here the full XBMC Logfile.

I read in the thread that other timshift problems could be solved by checking the unlimited size box. Unfortunately that does not help.
Btw. what is the idea behind the "unlimited size"? Because I can find many files with a size of less than 100MB in the folder. Is it correct? I would expect one big file if the unlimited size is enabled.

Code:
{
        "enabled": 1,
        "ondemand": 0,
        "path": "/mnt/timeshift",
        "unlimited_period": 1,
        "max_period": 3600,
        "unlimited_size": 1,
        "max_size": 2048
}

I used the timeshift folder on a ZFS Raid System, SSD and ramdisk, but also without success.

Any ideas what could cause the issue?

Yes this also fixed the issues for me. thank you.


RE: Timeshift Support - cable_guy - 2013-11-25

Hi all,

When I pause live TV then resume, it plays for a few seconds before pausing indefinitely.

I have ticked the box for unlimited as per the suggestions. Any ideas please?


RE: Timeshift Support - Cassiel - 2014-01-16

Seems TVHeadend with Timeshift support is still causing issues when pausing and starting the playback. Would it be possible to implement a client-side timeshifting for XBMC?
