Intel NUC Apollo Lake / Kaby Lake hdmi passthrough patch

    i just had a weird decode bug on hevc 10 bit content (dont know if other was affected too, bit in all hevc movies). I could see the decode pattern form time to time resulting in a blocky image. Reboot didnt solve it. any how, it was gone as is restored a backup with exactly the same settings.

    Edit. Seems like x265 is broken (blocky decode) once I had played one TV channel with deinterlace (method deinterlace, not vaapi). After reboot its fine again. But any how all other vaapi deinterlace methods kinda suck. ill test it anyway. Lets see if all of them break it or only a specific one

    Edit. other methods like VAAPI Motion compensate seems not to have that issue.

    Just started to use InputStream Adaptive but whenever the material is 23.X FPS i get blocks all over the screen. 25p runs fine from Aprime. Same for the most trailers in normal movie library. vp9 seems to be the issue. x265 is fine. same as x264.

    Ideas`?


    Edit: updated to latest release from 14th. VP9 seems to be fine now in trailers, but seems like that my EID issue came back. Sometimes once it switches the display refresh rate on my LG, the signal is gone. I can stop the playback and it returns as switching again, but sometimes it simply loses my display.

    I can report it works like it should, simply perfect.

    Tested all, including ac3, dts, dts hd / ma, opus 7.1, 2.0... latest firmware from few days ago, I have the i5 kaby nuc.

    But any how, im not able to install any addon like tvheadend in 8.2. Maybe a temporary repo issue?

    Ideas?

    Hi - have installed the LibreELEC-Generic.x86_64-8.2-devel-20171205 version on a NUC7I5BNH

    passthrough works perfectly with ,my DENON receiver

    ATMOS / DTS-HDMA / DTS AC3

    tested a variety of sources

    great work - thanks

    pass through for dolby digital and dts work fine with "adjust display refresh rate" on, but the HD-audio only passes through if its set to off, or at least the last time i checked it was that way.

    Are you confusing "Adjust display refresh rate" with "Sync playback to display"? Enabling the latter will disable audio passthrough - this is by design. The refresh rate setting should have no effect on passthrough, HBR audio or not.

    i'm pretty sure i got it right, its the option that changes the tv refresh rate to mach the video

    see your post mentioning it here: Intel Apollo Lake

    Ah, so that's what you're on about.

    The mixed up channels and lack of audio in early LE8.2 test builds due to the HBR patches were the primary reason those patches did not ship with official LE8.2 - "Adjust refresh rate to display" may have been implicated as one possible cause but there was never any point investigating further as backporting the HBR patches to the older 4.11.y kernel was clearly a bad idea.

    The HBR patches in LE9.0 (with a more recent kernel) are working fine and to the best of my knowledge "Adjust refresh rate to display" is not causing any issues.

    Which current custom release does contain the Apollo Lake Patch? - The Version escelade postet is from 2016 as far as I see...

    I am running the "official" Version of LE 8.2.3 currently - how can I switch?

    Was anyone successful with HD sound passthrough on Kaby Lakes with LibreELEC v8.90.005?

    I still can not get it to work on my Zotac ZBOX CI547.

    I thought the necessary patches were to be included in this release?
