FEL - Amlogic NO support

Can you read,I am not forcing to implement this feature,I was just asking,is it technically possible,that is it. Stop making drama out of nothing.

You could try this:

Use DoviBaker to bake FEL and BL into a single PQ12 16-bit rgb BT.2100 file.

Then use an encoder to transcode to a 10-bit vvc HDR. Problem is when you bake FEL and BL the combined precision is 12-bit. When you encode to 10-bit you are losing the extra 2 bits FEL gives you.

So I don’t think it’s technically possible yet. But you’d get very close.

I think internal processing of FEL in CoreElec goes 12-bit, down to 10-bit for processing, then back up to 12-bit for HDMI transmission (please correct me if I’m wrong). So even with FEL in CE, your display is only receiving 10-bit precision anyway (again, correct me if I’m wrong please).

Technically, it’s possible. But software is a completely different matter. Don’t look too far into the future. It will happen, but it will require a lot of time and effort—not artificial intelligence, which is just a search engine for databases, but real solutions. This format is only just emerging. There’s no need to rush.

For example, there are some developments and real solutions… I’m currently testing the picture-in-picture feature, voice input for Coreelec, a different look for TVs with a full TV guide like on Dreambox set-top boxes, Moonlight with built-in statistics, this is work with new NO releases… And many other ideas… You can’t even imagine how much time this takes in life. Everyone wants more right now and at this very moment. Yes, like everyone else, I want this project to be the best, and it will be! Everything in its own time. And then there are difficult life circumstances, the health of loved ones, a full-time job, and access to all the necessary equipment. And most importantly, time… Not everything is perfect, but it works, and it’s a shame that when someone tries to do something, the community always demands more and more. Everything in its own time.

Kodi does not have a PiP feature. It can handle only one decoder at same time.
AML is able to handle up to 9 parallel decoder. Since GXB.

Yes, it’s a workaround, but for now, it’s a perfectly acceptable solution. The software decoder is sufficient for resolutions up to 1080p, and there’s a 4K option that works just as well. I can attach a video from the camera, there are no changes to the CoreELEC code, these are plugins, skins … these are just tests, so it might be too early to show it to everyone…

If anything is wrong, please delete my messages.

Sorry, this isn’t the right topic for discussion. I just wanted to say, as was written above, that we need to be content with what we have now.

With today’s nightly the problem on the AM9 Pro has been solved. Now all is ok. Thank you CE TEAM. :smiling_face_with_three_hearts: :smiling_face_with_three_hearts: :smiling_face_with_three_hearts:

I was unable to trigger HDR from this video,it should be in VVC I guess.

Another way to get logs,maybe it would be easier for most users.

Enable ssh in CoreElec
Download and install termux on your android device

In termux type
pkg install openssh

Type this in termux,change it to your CE device IP
ssh root@192.168.50.87

default password should be coreelec

then paste log
dmesg | paste

It should give link with logs

We know but we are not the author of the module. Even Amlogic does not own the source…

I know FEL support for NO is new but what happened that made it all possible?

I had read many times that FEL support had been abandoned by Amlogic and none of their newer SoC’s would include it.

Was there a developer that made it all possible or did Amlogic have a change of heart?

It was not thanks to Amlogic. A developer named djnice77 was working on it for a while and I’m sure there was collaboration behind the scenes with others.

Tone map sdr to dv works perfectly. Thanx guys. Still not working sdr to hdr. I got black screen and no sound. Cant play any material, sdr, hdr and dv. After exit from that, gui is messed with purple colors.

HLG (Formula 1) → DV conversion works with the issue - the TV blinks and shows the Dolby Vision badge every 10 - 50 seconds.
Happens with both connection - via AVR and directly to the TV.
SDR → DV works perfectly.

Ugoos AM6B+ → Denon AVR-X3800H → LG C8

dmesg: https://paste.coreelec.org/SpinsRoute
Sample: 105.16 MB file on MEGA

Try to change your HDMI cable.
May be one of cables you use for test is not good.
No issues from my side on this sample.

update link please
