Openelec Build for OPI PC and 2 now with HW decoding

darqoq

@slaine: maybe someone will create a fork based on LibreELEC,
but, the main problem of "OpenELEC for OrangePi" is not OpenELEC but the old crappy kernel, video and graphics drivers.

There are some other reasons to create this fork, but don't expect that is "help with OrangePi".

Guys from openelec founded new project - LibreElec. Maybe they should help with OrangePi.

Main help could come only from Allwinner - when they will release HDMI specs, PRCM registers specs and possibly also VPU specs.

In the meantime - a BIG THANK YOU for making Openelec on OPI ONE such a pleasant experience !

Hi jernej, I'm having trouble with something that works perfectly fine in Armbian and doesn't in the latest OpenELEC fork I've compiled, which uses the same kernel, but different configuration.

I have a DVB-T tuner:

1. 048d:9006 Integrated Technology Express, Inc. IT9135 BDA Afatech DVB-T HDTV Dongle

Copy code

It works fine in Armbian after downloading correct firmware and not doing anything else, but it fails in OpenELEC:

1) OpenELEC loads the dvb-usb-af9035 module (which I can't even find anywhere, there's af9005, af9013, af9015, but not af9035...), which in turn doesn't register the DVB adapter frontend (device seems to be correctly loaded, but is invisible to all applications, "registering adapter 0 frontend 0 (Afatech AF9033 (DVB-T))..." is a lie) and some other errors occur.

Armbian loads the dvb-usb-it913x kernel module, not dvb-usb-af9035. Compare dmesg in Armbian:

Copy code

It looks like it tries loading both modules at the same time, but even if I unload and/or blacklist dvb-usb-af9035, it913x still fails.

Important configuration differences between Armbian and your OpenELEC fork, your fork has:

1. CONFIG_DVB_NET=y
   
2. # CONFIG_DVB_DYNAMIC_MINORS is not set

Copy code

Armbian:

1. # CONFIG_DVB_NET is not set
   
2. CONFIG_DVB_DYNAMIC_MINORS=y

Copy code

While I can just swap these around before I try building your fork again, I don't know how to deal with the second issue:

2) OpenELEC comes with older firmware dvb-usb-it9135-02.fw (3.40.1.0), my tuner needs 3.6.0.0, which is available here:

1. wget -c http://www.ite.com.tw/uploads/firmware/v3.6.0.0/dvb-usb-it9135.zip
   
2. unzip dvb-usb-it9135.zip
   
3. dd if=dvb-usb-it9135.fw ibs=1 skip=12866 count=5817 of=dvb-usb-it9135-02.fw

Copy code

How do I swap the firmware before the image gets built?

I don't have any DVB dongle, so I can give you just some basic pointers so you can fix it and possibly make a pull request.

1) This fork is using http://git.linuxtv.org/media_build.git at commit 66f4030 for backported drivers. Not sure how old is this, but I believe the code is from year 2014. AFAIK, Armbian doesn't use backported media drivers.
2) DVB firmware comes directly from https://github.com/OpenELEC/dvb-firmware.git If you would want inject or change something, this repo should be cloned and adjusted. Then you need to fix the repo address here: packages/linux-firmware/dvb-firmware/package.mk

tomaszd

Backported drivers mess everything up, I've noticed at least one patch fails to apply, new drivers conflict with old ones (af9035 and it913x both detect 048d:9006, briefly fight for it and both fail), the DVB stack and drivers that come with Armbian's kernel works fine in my case.

I have repackaged the dvb-firmware source with the firmware I needed and disabled backported drivers.

A powered USB hub is strongly recommended, the dongle will need to be unplugged and plugged in each boot and the pvr.hts TV addon froze the system at least once for me, you need a strong TV signal...

All in all a waste of time for any sort of "production" home entertainment system, I'd have to simulate unplugging and plugging the dongle in each boot... but it was fun to figure it out ;)

hi, how to off blink green led in last img(OpenELEC-H3.OPiPC.arm-6.95.1.img) or off all leds, script.fex?

In this case image name doesn't help, because there is no date/commit number. However, the only image which has blinking LED is test image with newer version of Allwinner's kernel. I didn't put any effort to figure out why it blink. I recommend that you try latest image from "Latest prebuild image" topic, or just try to disable all leds from fex file (deleting LED section should do)

leds blink off - delete [leds_para], after edit - green led ON, but does not blink. http://linux-sunxi.org/Fex_Guide no work
And have 1 bug this build: power button/menu/IR don't power off orange pi - all suspend off(sleep) , return to work after press power button.
What last buid without "power off" bugs, 22/03/2016?

As it already stated in FAQ sleep/power button functionality newer worked and it doesn't work. I already spent too much time on this.

Green led is by design used as power on indicator and red as suspend (but it doesn't work correctly). If you want to change this, you have to change the source and build your own image.
