yes but the file has the 8.1 rpu from @quietvoid L1L2 HDR10 BL test file.
I'll try to edit the original HLG 8.4 footage.
Did you succeed?

So after ups and downs with the delivery company I received my Xiaomi Mi TV 4K and can report on its capabilities.
Things that work:
- HEVC (high bitrate too) / AV1
- DTS (HD*) 5.1 & 7.1
— My Soundbar only shows “DTS Audio” for HD and compressed but by playing back the 5.1/7.1 HD Test files the channels are mapped correctly and it is highly likely passing through the right format using OMX.amlogic.audio.decoder.dtshd
- In the settings switching between TV-Led and Source-Led Dolby Vision
- DV MEL DT DL // DV 5 / 8.1 RPU
(Edit2)
- OTG Support with powered micro usb hub: 1TB External hard drive and ethernet. (around 120mbps)
EDIT: Things that don’t work now confirmed:
- DV (FEL DT DL)
— Tested with “black level pattern mp4/ts” & “RPU-FEL Test DT DL p7”, somebody please tell me what to look for in the last one. @Reset_9999 ?
Things that don’t work:
- TrueHD (any) +Atmos
- DTS:X
- The “Dolby Vision FEL Test p7.06 Dual Layer.mp4” I’m assuming it’s because it’s missing rpu? It plays until the 23 frame and then gets stuck.
- Any Single Layer Dual Track DV files

You will see a video from another movie over the orange picture if FEL is used and a couple of flashes if the RPU is used.

Is there a reference image for that?
I have Blank red until ~26sec then I get the Warner Bros over the red part, a stanley… over the blue part then clockwork over red switching to a movie scene at ~45

If you only see a blank red picture, it means FEL is not processed. I'll try to take a picture when I get home.
Do you see the flashes though?

I don’t get flashes with P7 only P5 and P8 RPU’s seem to work on the Amlogic S905Y4 sadly.

yep, unfortunately, it sounds like that device is doing fake DV with P7.

Here's what the FEL test looks like when FEL and RPU are 'working' as intended

thank's @staknhalo
the FEL and RPU test files can also be used to find out if your device uses the L5 active area metadata in the RPU.
if it uses L5, there will be black bars otherwise it will be fullscreen.
C8 internal player = black bars
Shield = full screen
x700 = full screen

OK, so you want to convert P5 to P8.1 but Apple is using an odd "max_display_mastering_luminance".
Please tell me the way convert P5 to P8 of this file.
This file have not info of Mastering display luminance, Maximum Content Light Level, Maximum Frame-Average Light Le

I recommend converting to DD+ 1536kbps with ffmpeg:
Code: Select all
ffmpeg.exe -i input.mkv -map 0:1 -c:a eac3 -b:a 1536k -c:s copy output.mkv
