Here you go.

No dovi.ko file in storage, DV files playback as HDR10.

ugoos.am8.dovi.ko renamed to dovi.ko in storage, DV files switch TV into DV mode but just display a blue screen.

dovi.ko get loaded and SoC looks support DV.
All your media is Profile 8?
You might share a cut sample as there were issues with P8 in past.

741

Yep but I donā€™t think itā€™s the correct dovi.ko for this box. The one Iā€™m using is the ugoos.am8.dovi.ko posted awhile ago.

No, this is media that plays perfectly fine on a S905X4 device in Dolby Vision.

This is a test file Iā€™ve tried:- Downloads Page - Demolandia

Itā€™s a Profile 5 video, without dovi.ko it plays back with purple and green colors and with dovi.ko again it switches to Dolby Vision on my TV then just a blue screen.

742

No, dovi.ko is correct. Correct kernel version and for S5.

Run fw_printenv hdr_priority and fw_printenv | paste

fw_printenv hdr_priority returns:-

744

Try fw_setenv hdr_priority 0 and reboot.
And maybe fw_setenv dolby_vision_on 1

745

Thanks, tried both, rebooting after each and no change. The TV still switches into DV mode and I get a blue screen.

746

Before try with fw_setenv hdr_policy 1.

If still not works:
In Kodi enable only component video and video/audio timing and enable debug.
Then start a ssh session and run:

dmesg -c
echo 3 > /sys/module/aml_media/parameters/debug_dolby

Then start a DV video for 1-3 seconds until you see the black screen - really short only! Stop again.

Then share the results by:

cat /storage/.kodi/temp/kodi.log | paste
dmesg | paste

It change mode from AMDV_OUTPUT_MODE_IPT_TUNNEL to AMDV_OUTPUT_MODE_SDR8. No idea yet why this happen. Will need to search a bit in code.

We got told the 4G version of the X10 does not support DV but the module loads and show it should work. Playback does start also in DV mode:

Thanks for taking the time to investigate this, let me know if there is any more information you need or testing you need me to do :+1:

750

I see same behavior in dmesg here with AM8. With P5 it switch from DV/SDR/DV/SDR/DVā€¦ until it end up as DV.

On 1080p the Player Process Info show wrong information SDR 444, 8bit but Vertex shows me correct DV-LL 422, 12bit. So this info isnā€™t ā€œtrustfulā€ at all.

Does OSD show up on your device or do it stay black while DV is playing?

If itā€™s the X10 4G variant you might return it as we got told ā€œonlyā€ the X10 8G does support DV. But I would not see now why this should be the caseā€¦

751

No OSD shows up just a black screen.

752

I have X10 Pro 8 gig.

I think a remember having to change a setting In Android.

Reboot from eMMc/ nand in CoreELEC

In Android settings
Screen Resolution

Check that you have HDR policy set to
Adaptive Hdr

And HDR Priority set to
Dolby Vision

753

Yep, I have that set.

I have no options in Android that refers to Dolby Vision :frowning:

Thanks for the suggestion.

754

Hmmmmmm

No Dolby Vision settings in Androidā€¦

Thats not goodā€¦

Maybe is best to return as you indicated earlierā€¦

755

So after opening the box and removing the heatsink unfortunately itā€™s not the J or K variant of the chip :frowning:

Strange, because the DV capability say 7, this is for DV. Maybe the fuse is burned but the licence not!?

757

Minix confirmed on their forum that the S928X will not support FEL, but convert it. Itā€™ll probably only decode the RPU and convert it to 8.1 like Dune does.

Minix claims Fel is hardware based but we know thatā€™s not true.
