You cannot use Bicubic or lanczos3, not enough CPU ponies on AMLogic devices.
So in this case 720p stuff will trigger a format switch to 720p, output in native mode, and then allow the TV to upscale?

Do you do this based on both horizontal AND vertical resolution (horizontal res >720 but 1280 or fewer horizontal samples), AND vertical (720 or fewer vertical lines) - to cope with letterbox and non-square 1280x1080 stuff? (If you just look at horizontal res the 1280 x 1080 could be confusing).

Or do you do a test after PAR has been taken into account (so 1280x1080 and 1440x1080 16:9 non-square stuff is seen as 1920x1080)

Hilariously you can end up with 1280x720 non-square pixel content that should be output as letterboxed 1920x720 in a 1920x1080 raster NOT 1280x720...

With the Vero 4K (OSMC) there where people complaining that playing a 2160p file didn’t work while you only had a 1080p display.
You know if you got this issue aswell with your build?

I've got a fix for that now, so will probably resurrect that test thread on the forums soon.

Cheers

Also worth knowing CvH's builds include an option to install specific DVB drivers for Hauppauge (which enables the WinTV Dual HD to run as a dual DVB-T2 device) or Crazy Cat's TBS drivers (as they aren't all in standard builds) 
Hey, thank's for the reply.
I already tried with Hauppauge drivers and with Crazy Cat's TBS drivers with no luck.
I even tried on a raspberry running OSMC, Openelec, Libreelec and Xbian, all of them find the DVB-T device (RTL2832) and the tuner (AT628) but none of them find the DVB-C demod (CXD2837ER).
Right now I'm trying to compile driver modules, but it's not being easy...

Regards

Hey!

so first thank you guys for having this great community!

I've got my c2 connected with OG round cable in to my sony tv, usb3. Now, iv'e installed vanilla libreelec first and than i installed the patch that you supplied.
I can't to seem to get c2 stable with the overclock, do you think its all about the cable? Should I put it in to adapter and in to the wall or is there something else that might be wrong?

Also when i put in the code supplied a few pages back to overclock the memory i just go in to a bootloop and i have to reinstall everything.

I would love you have c2 a bit faster, I have a good sd card today. Can someone please explain in 'idiot' how to get this done pleease Smile


never mind, the solution was that the tv didn't send out enough, even with usb3.. got it sorted now.

Hi @wrxtasy Just wonder are there any news about the new release?

This is great. It seems to work. Is it possible to update via Kodi to latest version and keep the voltage patch so the OC is stable?

Kodi has nothing to do with CPU clocking. That is a Firmware function. The following LE Kodi is running the latest Krypton 17.6

This version has some extra Kodi GUI options:

LibreELEC-Odroid_C2.aarch64-8.2.3.-GUI-options.tar

New Kodi GUI Options:
(auto 720 <<-->> 1080p <<-->> 4K resolution switching is included)

Kodi Settings > System > AMLogic...
- Set GPU clock rate to 792MHz (faster Kodi GUI)
- Force RGB output

Kodi Settings > Player > Videos...
- Disable auto resolution switching lower than 1080p (real handy for SD / HD - TV users when channel zapping)

Users should run their Kodi GUI at 1080p60/50Hz if they mostly watch 1080p content. The believe the Kodi GUI is only a 1080 resolution anyway.
Any 4K video content will trigger an auto resolution switch 1080p > 4K. You want your 4K TV using it's superior picture upscaling hardware to upscale all non 4K video content.

The code is mostly based on @Koying's SPMC Krypton work with a few small tweaks, the details of which start with commit #aoc8196 HERE (click)

I personally find this easier to use vs what is going on with the new Whitelist Leia refresh / resolution configurability.
Which for end users seemingly just adds a bunch of extra unnecessary complexity & confusion.

So if I update to latest officiel LE version from LibreELEC-Odroid_C2.aarch64-8.2.1-Oclock-Res-201712081016.tar I can keep stable OC of 1.752 GHz, or have I misunderstood?

Just simply update to the version above.

The file that set's CPU OClocking is not touched at all. That will all remain the same.
I still run mine happily at 1.752GHz. Smile

Indeed. This works flawlessly. Even to the point of not having to re-synchronize the sound any longer, compared to the official LE.
Dunno if it's the OC or your LE version  Laugh
Thanks so much. You really know your stuff

I will try the new version. One annoyance on my C2 running Libreelec is that the screen goes blank for a couple of seconds as the tv hunts for signal each time i do something. ie; playing a movie is fine - but skipping forward/back or stopping to go back to the menu causes the blank. The TV is 1080p 60Hz native.

I updated to LibreELEC-Odroid_C2.aarch64-8.2.3.-GUI-options.tar and encountered audio not working with certain audio codecs. I am using a sound bar connected optical cable to the TV with pass-through enabled. 2 chan AAC will not pass-though, no issues with 6 chan AC-3. For testing I tried disabling pass-though then 6 chan AC-3 & 2 chan AAC both did not work. Never had an issues with previous versions and have been using the same setup for 2 years now. Rolling back to LibreELEC-Odroid_C2.aarch64-8.2.1 and have no issues. Thanks for all your hard working adding new features and options keeping great life in the odroid!
