Odroid N2 test builds

I had wake up from suspend with CEC issues and also wanted more options than the tv remote could offer, so I bought the Harmony Companion with Bluetooth Hub, right from the start I had a very hard time connecting N2 with Hub/bluetooth, finally it paired and worked perfect quick and snappy just like a keyboard.

The issue is you really don’t know when it will work or not it can work for 2 days and suddenly after suspend or reboot it will not connect what so ever I have spend hours on this issue and really need help fixing this, @jbrisbin have similar problem here BT Keyboard Fails to connect H96 Pro + CE 9.0.1 [WORKAROUND FOUND]

Please let me know what logs is needed to look in to this, thanks…

EDIT: one of the errors I seen when trying to connect is “Input/Output error”

@Bindou try changing the following setting to off when you have GUI at 4k resolution, it may help improve the feel of the GUI.

Settings>Interface>Skin>Configure skin>General>Use slide animations

Hi,
I just tested the version of April 18th, but the problem of gradation of colors on 10 bits is not corrected for me. :frowning: https://test.coreelec.org/ray/CoreELEC-Amlogic-ng.arm-9.0-devel-1555651433.tar

On the other hand, I do not know if it is me who kidding, but I have the impression that the fast forward is much more reactive. Very good! On the other hand, there are artifacts that sometimes appear when you make a quick advance on Billy Lynn (4K HDR 60 i/s).

How can you tell? Do you have a spectrometer?

To the colors.

Top: Beelink GT1 @ S912
Bottom: Odroid N2 @ S922
(See the gradient in the sky. It is present on all the applats, in many films HEVC 4K HDR10 BT.2020)

And that was already on the GT1 @ S912 a few months ago, before the update “Automatic color space / color depth switching”. But maybe it’s something else …?

The picture on N2 looks better, and you need to re-calibrate with test pictures running on N2.
Hue, Saturation and Black level differ on these two boxes.

Edit: I use 3 Amlogic boxes, S905X, S912 and S922. To get best picture I have 3 different calibration settings, one for each.

You are assuming S912 is correct. Without a Photometer and a proper calibrated TV and Calibration Video you can’t be sure.

This is a known issue. We are looking for the cause.

I guess the S912 is ok because I have the same result on platinum Bluray and internal player of the TV.

I think I can not explain myself well. I’m not talking about colorimetry, I’m talking about the color gradient. Look in the sky, with the N2, we see a banding effect. https://en.wikipedia.org/wiki/Colour_banding
It is obviously much more obvious in “real”, than in photo.

I get that, but only with live hd channels.

OK this is different then What build are you using?
I heard reports of color banding. I need a sample. It’s probably another post processing Bullshit from Amlogic like the sharpening that lead to cartoon effect.

It’s probably because N2 has sharper and more detailed picture, so the gradient can be seen.

Check what cs and cd is used with dispinfo.

Or dispinfo command while playing the video.

SSH to your box and run dispinfo, then post the URL here.

Yeah it was captured with it-keytble so will try UART route as need to try and understand what is happening with the Bluetooth Hotack_RC as it is also not functioning correctly within CoreELEC also.

Been using the aboxwireless.evmap as that is for Hotack_RC but the button mapping is a bit off and the ok/enter button does not register anything, I say anything it has worked perfectly twice but after reboot back to not picking up ok/enter which makes it non usable. As /etc is no writable so will maybe have to clone and mess around with the maps or edit the filesystem prior to flashing.

I have a few nodemcu lying around that look flashable for UART so just need to dig some female to female jumpers and have a look at getting that going to start with :slight_smile:

Thanks again, E.

I confirm the bug …

On the top : GT1 -> Color space OK
On the buttom : N2 -> Color space Error

Don’t claim it is a Colorspace issue because it isn’t!

I can’t see a difference in your photos because I’m looking from my phone. Although I can imagine it is like the banding issue we had with dithering.
