High CPU load and wrong reported clock speed in LE8

1st Official Post

    Hello...

    LE8 final has the same issue as the Betas.
    Maybe thats a Kodi problem due to changes in the video framework/new player....

    On video playback, live tv HD and SD CPU load is 3-4 times higher than with LE7 Kodi 16.1.

    To be sure and to proof it i disabled any power saving downclocking. So the system is running at a fixed clock speed.

    Also clock speed is reported wrong .

    Both issues on 3 different x86 systems.
    Asrock N3700 onboard Video
    Asrock j1900 nv gt730
    Intel i7 6700 onboard video

    First I thought it is a lack of Hardware Rendering but it is not. It is using the same deinterlacing/scaler settings as kodi 16.1(LE7).

    Maybe someone encountered the same....

    Regards

    Is vaapi and/or vdpau enabled?

    On the intel gpu vaapi is on only
    On nv gpu vdpau is on only

    Enhanced shaders GLSL
    HQ Scaler above 10℅

    Scaler Lanczos 3 optimized
    Intel vaapi motion comp
    Nv vdpau deinterlaced

    Settings are exactly the same on v7 and v8

    (The j1900 GPU (4 EUs) is not able doing smooth vaapi deinterlacing and upscaling HD material that's why im using the nv card here)

    For testing i put the nv in the other System.

    But on both intel and nv CPU load is higher with LE8.

    LE7 CPU load is 8-16℅ intel 5-12℅ nv
    LE8 CPU load is 25-65℅ intel 20-45℅ nv

    So higher load on intel gpu...

    Krypton adds dithering to video processing causing higher CPU load.

    In worst case you may get 100% CPU load and video stuttering on slower CPUs.

    Dithering is enabled by default, your settings level has to be "Expert" to be able to disable it.

    Good suggestion!

    but, dithering is turned off entirely in LE8.
    Was the first thing I dissabled after fixing refresh rate.
    Also audio settings are the same as in LE7.

    It looks like it is the new videoplayer in kodi or a driver issue on x86 hardware in LE8.

    I don't have a build system at the moment to build a version of LE8 but with kodi 16.1 if this is possible.
    (Or LE7 with kodi 17)

    What I don't understand ist why is this a x86 problem never heard of such a behavoir on pi or arm hardware.

    Is the kodivideoplayer not as much optimized for x86?
