Code:
Color range                              : Limited
Color primaries                          : BT.2020
Transfer characteristics                 : PQ
Matrix coefficients                      : BT.2020 non-constant
Mastering display color primaries        : Display P3
Mastering display luminance              : min: 0.0050 cd/m2, max: 1000 cd/m2
Maximum Content Light Level              : 1000 cd/m2
Maximum Frame-Average Light Level        : 986 cd/m2
  
No - that bit of Media Info - specifically
Code:
Transfer characteristics                 : PQ
tells you it's a video containing HDR content, which the C2 can't play in HDR or convert to SDR.

So in this case the file is completely unwatchable , colours are completely reproduced wrong?

 Yes - that's an HDR10 format video (PQ = Perceptive Quantisation which is one of the HDR flavours, and one that isn't SDR backwards compatible without conversion).  The C2 can't output HDR nor can it convert HDR to SDR.

Hello

Looking for the best build for c2? I am on latest coreelec now.

If I want to overclock, is wrxtasy build best then? Where do I find his latest?


17,6 or 18 dosent matter. Only use kodi for plex and playchannels.

What do you think about MECOOL M8S PRO W with amlogi s905w at 35 euro ? It can output 4k HDR 10 correctly right?

 The S905W is a cut-down S905X (it won't do 4K at >30Hz)  It's not clear whether there is a good kernel that can support full 10-bit paths (required for HDR content without banding).  There are still some variations in 10-bit vs 8-bit dithered support in S905X kernels I believe, and I don't think the S905W is as popular by any means, so the level of understanding and research for this SoC is reduced in comparison?

At the moment I think S905X and S905D SoCs are the favoured long-term AMLogic platforms (the S912 performs well currently too - but may have long-term support issues with the current hacked Android GPU drivers)

The S905X2 - which is a totally new chip (not a tweak of the S905X) AIUI - is getting some interest but I don't know how well supported it is.

LibreELEC-S905-ARM.8.2.4.2-C2.img.gz

The GPU Overclock will be an option in Kodi Settings > System > AMLogic

Also on the SD card/eMMC the boot.ini file can be modified.
Because the C2 has a decent heatsink you can run a stable 1.752GHz CPU clock.

That will work, but only for 24p 4K HDR Bluray Rips. No 50/60fps 4K HDR test clips.
As @noggin said the S905W is limited to [email protected]

LibreELEC 8.2.5.x and CoreELEC Kodi Leia have S905W 4K HDR capable images. The S905W runs the coolest of all the AML chipsets.

Also for high bitrate 4K HDR Bluray Rips you need Gigabit Ethernet or a direct connected HDD or a USB3 > Gigabit ethernet adapter.
The S905W/S905X devices have 100Mbit Ethernet only.

Are these confirmed to pass 10-bit video cleanly - or could they be 8-bit with dither as some kernels apparently are?
