Raspberry Pi 5: purple/green colors (the reason)

  • I have issues with Kodi since forever, some movies are just showing purple/green colors.

    And it is pissing me off since forever as I need to get a different encode.

    I think I have found why.

    My TV (Samsung Q90T) doesnt support Dolby Vision, which I am aware of and I am avoiding such movies.

    My setup:

    RPI5 ----> Denon x1700h ----> Samsung Q90T

    Now, even if TV doesnt support Dolby Vision, AVR does support it.

    What the problem is, that some "copyright holders" are releasing movies with both Dolby Vision and HDR embedded.

    And in this scenario, probably Kodi, sends Dolby Vision data instead of HDR.

    I was looking for an option to prevent AVR from advertising it is DV capable, but havent found any.

    Is there any option to force Kodi to send HDR data instead of DV?

    (I have confirmed this on two movies i had issue with. In both cases they were distributed as non DV release but had DV data attached)


    I have found this:

    Probably Kodi within libreelec wasnt build with setting to allow disabling of Dolby Vision.

  • Pi 5 dont support DV and not DV to SDR or HDR.

    I am saying that the Kodi is not taking HDR data if it encouters DV data in same movie. Or rather prioritizes DV. I dont see what Pi 5 support has with that. I cant share you the test movie but I am sure "copyright holders" can ( Foundation.S03E01.A.Song.for.the.End.of.Everything.2160p.ATVP.WEB DL.DDP5.1.H.265 NTb.mkv )

    Kodi has an option, to disable DV, actually even exposed by UI, but it is not there in libreelec. Currently digging trough mk files to find where you build it.

  • The Raspberry Pi 5 does not include the specific hardware components needed to perform the complex calculations required for tone mapping HDR to SDR. Nor DV to HDR so if your files dont have fallback to HDR then colors will be wrong.

  • In case of UHD Blu-Rays it is mandatory that the DV video stream contains a HDR10 core stream - which kodi will pick up and play just fine.

    For streaming content this is not true and a DV video stream contains only DV video - which kodi won't handle as there's no DV support in linux.

    TL;DR: it's expected that your pirated "webdl" file won't play fine if it contains DV.

    so long,

    Hias

  • It is not really quite assuring to give an "example" with a filename which is usually used on torrent sites to say that it is legitimate content.

    I currently have 2 4k Movies (im ripping my dvd/blu ray collection since february...and im still not done...uhd will come last as that will take the most time) with DV (the hdr type while playing is shown as dolby vision in the media info tab) which i ripped from my own discs and converted with handbrake.

    So i guess handbrake adds a kodi compatible layer into it. (or better compatible hdr info into the container)

    A non re-encoded rip looks fine too.


    So maybe you should do that stuff yourself instead of loading it from third party sources?
