Dolby Vision now possible through MP4 Mux.

The AM8 has the successor chip to the AM6B+ that everybody is boasting about. And like I said in my post, since the AM6B+ is sold almost everywhere in my country and beyond (Europe) the AM8 is actually cheaper with a more direct availability. So I don't necassarily want it because it's 'better' but because it's more easily available and actually cheaper to get.

you don't get the point. FEL support needs both hardware and software. At this time, software does not support FEL on AM8. It does not matter if it is newer or better or cheaper.

I got that. I know it's being worked on and I have a sony x700 to keep me satisfied for FEL playback while the software part of the AM8 gets optimized. I'll wait if need be, the development at CoreElec seems to have made great progress in the last few months so I'm pretty sure we'll get something working sooner rather than later. And if not then I can just act accordingly then. Am in no way in a hurry to get a streamer that works.

do you know if Amlogic S928X-J has two decoders which is required for FEL decoding?

According to Portisch's (a developer for CoreElec) response to a statement about multiple decoders and the S928X chip, it does.

Statement:
''You cannot support FEL via a firmware update because FEL is actually 2 videos overlaid on top of each, so it requires 2 H.265 decoders which this chip does not have. The S905X5 apparently has 2 decoders so that might be able to decode FEL depending.''

Portisch:
''This is not true, there up to 9 decoder in hardware supported since years. I think since g12a.
It’s just not usable as Kodi is only able to handle one decoder and not two simultaneously like for PiP.
We use for FEL already two decoders but the problem is when one frame decode fail all get stuck..''

[cpm00]

I guess maybe talking at cross purpose, the chips have multiple decoders - but they are for different types of decoding h.264, AV1, VP9 etc.

DoVi UHD BluRay needs 2x h.265 (1x h.265 2160p @ 60fps and 1x h.265 1080p @ 60 fps).
I can not find anywhere which explicitly indicates the S928X can do that combo - though it is possible it can.

Note: Kodi is just passing down the ST-DL video stream to the AMLogic drivers/codebase to do the actual decoding and composition of the two h.265 (HEVC) streams (BL and FEL) for DoVi, recently there was an issue in CoreELEC 21 with seeking - landing in between I-Frames and the decoding becoming stuck - that one was solved.

Presuming the chip is good the next hurdle will be getting all the open source linux drivers required for CoreELEC - from what I see they have not been released - some important elements are missing, and all are only available for Android - for the versions the S928X needs.

Would need pressure on AMLogic or more likely the 3rd party box makers to put pressure on AMLogic to get the drivers released for linux.

Speculation: Higher bandwidth streaming is arriving - and I would dare say this will ultimately surpass DoVi UHD BluRay if the demand is there i.e. will bump to 12bit when sensibly priced consumer displays become available to close any remaining gap.

No work is being done on the AM8. S905X4-K doesn't support FEL. Also the AM6B+ is available on aliexpress $152 USD plus taxes and free shipping.

I know they're waiting on drivers and other things so it's in the queue. We tested the Nokia boxes extensively but sent them back to Amazon because one wouldn't start up anymore, so in the end it didn't really matter either way.
The AM6B+'s on Aliexpress for $152 I've found myself too but after you login they all become $184 or more (I have a CC limit of $175). Probably some deal for first time buyers that gets removed after you log in. If yours is a different one that stays at $152 I'll gladly take that deal.


UDPATE: Bit the bullet and bought an AM6B+ from Aliexpress for $190 including shipping by using afterpay . It was the cheapest I could get it from Aliexpress. Should arrive in about 2 weeks.

The seller PLAY TV has the cheapest price I found. $166.28 with tax and free shipping. Im waiting on my second AM6B+ now.

[sultanmehmet]

Ordering from Play TV would have cost me $192 all combined. I ordered it from Diffingle Store where it was a little bit cheaper. A second one, nice.
How is fast forwarding FEL movies? Does it crash in CoreElec while attempting to go to the next chapter or fast forwarding?

Next chapter and fast forwarding works great. Best player to have right now for local playback.

Wow I’m an idiot lol. Thanks for the response🫡

[dysprosium]

HDR10 playback is fine as long as your player doesn't tonemap DV to HDR10 like the x800m2/x700 can do when you have DV set to ''on'' and play a TS/M2TS rip.

Thanks for your response, one more question for you:

You've noted that P5 > P8 due to the colourspace being equivalent to 11.5-bit YCbCr > 10-bit YCbCr.
Is there a noticeable difference between P8 and P5, assuming that it's the same master/streaming quality, on consumer-grade 10-bit panels?
Similar to how there are certain FEL films e.g. Saving Private Ryan where the 12-bit BL+FEL+RPU has noticeable brightness/colour/quality differences compared to the 10-bit BL+RPU?

Sorry to ask you so many questions but you are truly the authority on all things DV!

Not really.
But any AppleTV webdl has some static color reshaping in the RPU which messes up the colors IMO.
You have plenty of P5 vs HDR10 BL comparisons here: https://docs.google.com/spreadsheets/d/ ... =917134052
