[RPi3B+] 3D Playback on 3D Televisions

    ADMIN NOTE:

    The following thread describes a 3D playback tweak for newer hardware revisions of the RPi3B+.

    Older hardware revisions of the RPi3B+ work without that tweak on LE 9.2.8.

    Newer LE versions (LE 10+) don't support 3D anymore.


    I bought a Raspberry Pi 3 b+ because it was recommended to play Frame Packed 3d movies.


    But now I have the problem that I can't get an HDMI output with the necessary LibreElec versions 9.2.x.

    Explicitly tested were 9.2.8 and 9.2.6. With the latest version for Pi 3 there was a HDMI output so I exclude a general hardware error.

    I would use the latest version, but I bought the pi 3 specifically because of the 3d function.
    Has anyone ever had this problem or knows how to solve it?

    Or, is there possibly a problem with newer Pi 3's?

    The same thing happens with Osmc the 3d builds don't work while the newer ones do.

    Not sure without digging but if so, the simple fix would be to copy bootcode.bin/start.elf/fixup.dat from a working new image to the 9.2.8 image and see if that helps.

    Another possibility is general bug fixes and improvements have improved compatibility with that specific TV.

    What popcornmix has sugestetd has totally worked for me.

    I have bootet the newer Version(12.0.2)from the rasperry pi imager and clicked through the Setup, after that i shutdown the pi and moved the files bootcode.bin/start.elf/fixup.dat on the Desktop. Then i installed the 9.2.8 Version and overwrote the files with those from the Dektop.

    Thanks for the fast help.

    Hi,

    could someone clarify the "don't support 3D anymore"?

    Does this only apply to the hardware-part (hdmi-framepacking and/or full MVC-decoding), or *anything* touching 3D? Currently, even SBS/TAB playback in 2D ("unsqueezing" one half to 16:9) does not work anymore, is this expected?

    If so, shouldnt the options (and maybe the mkv-3d-mode-detection) be disabled or hidden in libreelec-builds?
