TimeShift issues

Added by Sulla Sulla over 8 years ago

Dear all!

I have timeshift issues with my tvheadend headless server setup under ubuntu linux:

I run ubuntu 14.04.1 LTS wit a 3.19 64bit linux kernel and tvheadend 4.0.8 installed from the official repository (deb https://dl.bintray.com/tvheadend/ubuntu stable main).

Everything is working nicely, except for timeshift.

Everything includes:
  • watching live TV via tvheadend web-interface and VLC player
  • watching live TV via Kodi tvheadend clients
  • recording to disk
  • watch recordings
  • setting timeshift parameters in the web-interface
  • descrambling with oscam on the same server
TimeShift only works a bit, irrespective of clients (list see below), this means
  1. I can pause liveTV and then start playback a few minutes later. It starts normally but suddenly drops out of timeshift and jumps (I believe directly and without visual glitches) to liveTV without user intervention.
  2. I can jump back 10sec or 30sec, but then playback starts sometimes without sound, sometimes with sound and sometimes the video is frozen. When I wind forwards to catch up with liveTV, I fall out of the station and liveTV stops.
  3. winding forwards and backwards in TimeShift is possible, but very often the vidoe in the client freezes, stutters or crashes.
  4. when KODI and tvheadend is the client, the time indication during timeshift does not really make sense to me, but probably I just do not understand the reading.
Timeshift settings are:
  • on-demand: no
  • unlimited time
  • unlimited HDD size
  • use only RAM (I also tried to stream to HDD which fills up as expected, but playback does not improve)
My hardware is:
  • AMD Athlon X2 3800+, socket 939 processor (processor usage is generally less than 20%)
  • ASRock 939A785GMH128MBSP Mainboard
  • 4GB Ram
  • 40 GB PATA HDD for system
  • 80 GB PATA HDD exclusively for TimeShift
  • 4x DVBSky S960 USB receivers
  • smargo smartreader v2 for oscam
clients are:
  • Windows VLC player with HTSP plugin
  • Windows VLC player directly from tvheadend webinterface
  • Linux ubuntu desktop VLC player
  • raspberry Pi with Kodi 6.0.1 and tvheadend client addon

Anyone knows what is wrong with my setup? Is my server hardware too old and too weak?
