DVB-T2 HD and high CPU load on Wetek

  • Hi,

    Yesterday, the "DVB-T" was switched to "DVB-T2 HD" in Germany.

    The Wetek Play box and DVB-T was working very good, but now with DVB-T2 HD my box
    have a very high CPU load and the video output is very very slow. (unusable)
    The sound is working.

    I'am using the VDR addon.

    Watching TV (DVB-T2 HD) is not possible.

    Here a output of "top" when I try to looking live TV.

    Are you know if the Wetek play box can handle the new codec H.265?
    Do you have a idea what I doing wrong?
    Is VDR the correct PVR for DVB-T2 HD?

    Many thanks
    Michael

  • Unfortunately WeTek Play 1 doesn't support hardware decoding of H265 video, thats why you have high CPU load, because Kodi uses software video decoding in this case.
    You may consider WeTek Play 2 that does support H265 decoding.
