Do the Homatics Box 4K V2 and Pro models support DV P7 FEL?
Amlogic T931G supports dual-layer Dolby Vision playback. Its performance is comparable to the S922X-J/K. I found this out by swapping the chip. Currently, itâs officially used in the Google TV Stream. Has anyone tried booting CE on the Google TV Stream?

Whatâs that x96 board from that you stuck it to?
Thereâs an X96 TV box with the S922X chip. This is its mainboard, sold by a secondhand dealer, and the S922X has been replaced with a T931G.

What is the Google TV Stream? The 2024 Google TV Streamer uses a MediaTek SOC. Did you salvage that chip from a Google board or did you only ever have the SOC?
The Google Nest Hub Max used a T931, but I doubt it was DV licensed.
https://wikidevi.wi-cat.ru/Google_Nest_Hub_Max\_(H2A) yesďźyou are right.
Thatâs great if you happen to have 2 $250 devices to disassemble and mate together to make an Am6 out of them.
But could you just put an s922z on that board?
Certainly cube gen 2s are cheap and plentiful and it could use the port expansion+ram upgrade.
Itâs definitely not cost-effective to do this with brand-new devices. Thereâs a thriving second-hand market called XianYu in China, where specialized dealers collect cheap used equipment, then refurbish and repurpose them. Only this way can the price be low enough.e.g VIM3+S922Z

This isnât actually an S922Z from a Fire Cube, itâs just a non DV licensed S922Z with no efuses burned? And if that is the case, why replace a non-licensed A311D with a non-licensed S922Z?
The S922Z is a custom SoC, and the POP1-G is also a custom SoC, which includes Dolby Vision licensing.
Not all S922Z socs are DV licensed. The âZâ doesnât indicate DV licensing like -K and -J.
So the VIM3 with S922Z transplant can play DV? And it doesnât have verified boot & encryption enabled like those in the Cube do?
Hi,do you have any foughts,why this DV file Request for a Dolby vision pluge pattern ¡ Issue #4 ¡ test-full-band/tfb-video ¡ GitHub looks different,If I play it from android squares at left are missing:
If I play it from CE squares are visible:
My guess is that android is just cutting black levels to reduce potential noise from video signal.
I get an entirely different result. Is there a photo from the creator for what itâs âsupposed toâ look like?
I have no clue,I wish that there was a reference of how it should look like,but I converted this video to DV8 video with HDR base layer,with HDR it has squares on left side.
Actually there is more into it,I found out that at some point TV box or media player could just crush black,if reference black for HDR should be at 64 some units cut it way before whey should,at 76 or so.
But I need to do more research.
Without a reference I couldnât draw a conclusion.
Your first screenshots the backlight is way overbright compared to uled display with local dimming.
Local Dimming High - I can just barely make out the white band on the far right, the rest of the screen appears as dark as when itâs off.
Local Dimming Off - I can make out the far right band and just barely the one to the left of it and it looks closer to your backlit display.
No tests on my display show the square blocks on the left.
Okay, Iâll try to explain each step,in order to make it more visible and my phone camera to capture information, Iâve set black level from 50(default) to 57 or whatever,it doesnât really matter,just to check if TV gets the signal.
I would like to find out,if certain media players just clip black levels for HDR content.
Link to s922x dovi file seems to be broken.
Gitlab repo is temporarily down, added a mirror link to the OP.
