Openelec Build for OPI PC and 2 now with HW decoding

This bug is present for a long time. Issue is in mali framebuffer driver. It doesn't detect new resolution. I will implement workaround soon, so the driver will be completely closed and opened again at every resolution change.

The trouble here is that Kodi seems to remember last resolution and sets it at every boot. Workaround for that is that you change resolution in script.bin and then boot without HDMI cable attached. After you are sure that Kodi is fully started, you can reconnect HDMI.

P.S.: Images for all boards are the same. They differ only in script.bin and U-Boot configuration.

now working but,dont boot with something in usb port,without boot and after solve this problem.

Which board? Can you attach serial console and provide the output from the failed boot? I tried this many times with my OPi2 and it never failed.

jernej, could you share the settings used for compiling media_build?

What do you mean by "settings"? Everything related to media_build, including build instructions, can be found here https://github.com/jernejsk/Open ... drivers/media_build and here https://github.com/jernejsk/Open ... patches/media_build

yeah i tried your media kernel modules on Armbian and they all worked when loaded with --force
however as i compiled them myself for Armbian, rc_core failed because double exporting a symbol

so you somehow managed to cherry-pick remove all stuff from rc_core that is in the kernel already?

Problem is that Armbian has rc_core driver built in. If you want to load newer one, you have to recompile kernel with disabled rc_core or marked as a module. Basically nothing in kernel should be marked with "=y" if you want to load media_build

yep, thats what i did afterwards, to have modules loadable without --force
but, i could load -your- rc_core.ko on the stock kernel with rc-core builtin...

Here is update file with experimental HW CEC implementation, thanks to jodamm (https://github.com/jodamm):

Please test it.

CEC It works well

, but if you turn off the TV and then turn it on, no longer works

. LG TV. 55LA965V-ZA.
I think this could be easily solved , for in the image of zidoo for android, the hdmi is detected every time the TV is turned on.

Unless I'm mistaken, those two implementations are completely different. I think this HW implementation is missing hooks on monitor (un)plug detection events... This is understandable in this early stage.
