S905X4-K media processor (special version with all licenses)
S905X4-K media processor is the most advanced version of the latest media processor from Amlogic which includes all possible technologies and licenses: Dolby Vision, Dolby Atmos, DTS.
I am pretty sure that quote is overstating things.
Yep, thats sei robotics product from brand homatics. Dune just sell, and give one media player app for that. The codecs hopefully will be available soon. Currently from the android, missing the dts-x, and the dolby vision profile 7. Others like HLG, av1 Truhd, Atmos, are supported.
And welcome to Homatics brand, as official supporter the CoreElec
Now we just need to find out if the S905X4 really contains two video decoders.
We know that Profile 7 FEL decoding works on the S922X (Ugoos, Minix), the S905D3 (CCwGTV) and the S905Y2 (TiVo Stream 4K).
From the datasheet:
S922X: Support multi-video decoder up to 4Kx2K@60fps+1x1080P@60fps
S905Y2: Support multi-video decoder up to 4Kx2K@60fps+1x1080P@60fps
S905D3: Support multi-video decoder up to 4x1080P@60fps
S905X4: Support multi-video decoder up to 4x1080P@60fps
In principle, it should only depend on the dovi.ko module and it looks like they have removed Profile 7 support in the new version.
@Portisch Is it possible to activate this second video decoder module under CoreELEC? Or is the DV stream fully handled by the dovi.ko module?
This is what something different. Amlogic hardware is able to handle 8 decoder in parallel. Kodi can only handle one. DV decoder is something different.
DV decoder does exist since S912 what I see in source but was never be used.
So by the sounds of it no S905X4 device will be able to play DV content, unless they are the S905X4-K Variant?
Quite frustrating and confusing with all this licensing, you’d think it would just be enough that the actual TV would just have to have the sufficient licensing in place for DV, and that any device connected to the TV is just simply able to play content without any DV licensing woes - as long as the hardware is capable of course.
My Philips 55OLED807 has Android TV you see and the TV has Dolby Vision, therefore the latest nightly Android builds of Kodi or Kodinerds will playback DV, but then I lose out on TrueHD Audio via the built in Apps, and I just love CoreELEC as a dedicated playback device.
If this is to be believed Dolby_Vision_stuff - Google Tabellen only the Minix NEO U22-XJ or Ugoos AM6B Plus with slimboxtv firmware & Kodi 21.x can play real DV HDR profile 7 (BL+FEL+RPU) files - but as you can see from the comments, it’s dicey at best.
AIUI Dolby really don’t want that to be the status quo.
Every device that touches Dolby Vision encoded content has to be Dolby licensed AIUI, particularly anything that encodes, decodes or displays it.
It’s one of the major reasons that Dolby Vision is nowhere to be seen in HDR live broadcast production, only in some cases the final encode for delivery to viewers. Most live production is in HLG and/or SLog 3 as a result.
