[ROM] Unofficial OpenELEC for MK808B+ and MXQ

[xitpu]

The kernel seems to change the value to 0xf at various times so setting it once at boot to 0xb isn't sufficient, but resetting it in a loop does the trick, e.g.:

 ( while :; do sleep 5; echo 0xb > /sys/class/amhdmitx/amhdmitx0/cec_config; done ) &

Now CEC works but box always stays on when other devices are switched off.

Unfortunately even in this way, sometimes, the MK808B Plus is turning off...even with 0xb enabled...
I have to disconnect hdmi cable while I am not using the device

Kszaq, can you help me how can i patch the kernel?
The otheqr dvb-t stick (1f4d:d803) it is supported since kernel 3.6 but have other HW id as others. It is rtl2832u, but come from a hungarian vendor called alcor..
I read articles about it, but im not skilled with Linux.

I can patch the kernel via ssh? Or how can i manually added this usb stick hw vendor and id number to kernel?

You need to recompile the kernel to patch it or at least recompile the modules. With OpenELEC, the easiest way is to download the source and compile it with patches but it takes some time if you do this for the first time. I built a test image for you with the patches you requested:

If your stick is still not recognized after this update, make sure that the appropriate kernel modules are loaded.

Very Big Thanks!!!!
Working the stick already!!!
Can this patch stay for future releases? In central Europe many people use this stick.

Thank You Again!

This kernel working with wetek play too?

I will keep the patch in future releases since it is needed by you and does no harm to others.

The kernel binary won't work with WeTek Play but I will push the patch to my GitHub soon and make a pull request to Codesnake's repo. If he chooses to accept it, your stick will work with WeTek Play as well.

Can you check whether your other stick - the PCTV/Pinnacle one - works after this update?

Both stick working
I controlled better now, and there is a problem.
With new soft overall has mxw no audio output at hdmi. No audionat movies, music, etc.
At settings panel diappeared audio passtrough settings,
Thanks for the pushing to GitHub, please keep me informed about codesnake accept or not the patch..

Thanks Again...

#edited
With watching dvb-t channels sometimes catch the playback with both tuner.
Audio still missing over hdmi, I try restart, etc.

thank you for all your work kszaq
i already set up 3 MK808B PLUS for my friends and more are on the way

is it possible to include an overclockable kernel like in cyanogen roms?

it's "fast enough" for everyday use but scraping/updating a big library could always use some speed boost

[shamanNS]

Guys, what temperature (check over SSH via "cat /sys/devices/virtual/hwmon/hwmon0/temp1_input" ) are you observing on your MK808B+ while running OpenELEC? I'm getting 66-69 °C while idle (using ondemand governor), have not even added my samba shares to XBMC, OpenELEC/XBMC currently just shares 1 USB flash via samba.

On Android it was 50-55 while idle, around 63 when playing HD video over LAN.

When HDMI cable wrong, then why working cec with 5.0.5. 09-03-2015?

I have wetek player too. With 5.0.6 is working, but cec name is missing.
Maybe remove from cec config one real name or something changed with configuration.
I twice make a probe :
5.0.5. 09-03-15 cec working
5.0.6. Tar update cec isnt work.
5.0.5 09-03-15 downgrade cec working again
Clean install 5.0.6 cec isnt work
Ckean install 5.0.5 08-03-15 cec working agsin

The same problem for me. I updated openelec to 5.0.6 version and cec stopped working. (MXQ - Sony Bravia Sync)

This is very odd. I will make a clean compile for the next release to prevent residue from my test builds breaking things. For the time being, if you want to use 5.0.6 you may copy KERNEL and KERNEL.md5 from 5.0.5 release and SYSTEM plus SYSTEM.md5 from 5.0.6 release to the Update folder.

Yes. Cec function is back now.

@envagyok, @mike77: Sorry for the non-working audio, this is a result of my trials with HD-Audio (unfortunately I haven't had any success with it yet). Here's an updated build, the audio should work again: https://app.box.com/s/u4zeo847ht9d5w3leptc6gllebrt0hqz

I have also made a pull request to Codesnake's repo: https://github.com/codesnake/OpenELEC.tv/pull/54

I'm not familiar with CyanogenMod for the MK808B+ - could you please link me to the kernel source code? You should also keep in mind that an overclocked device may overheat, especially with the tiny heatsink the MK808B+ has.

On Android it was 50-55 while idle, around 63 when playing HD video over LAN.

I am getting 50-55°C when idle, <=70°C after playing some H.264 720p content. This is with hotplug governor which I think is also used in Android builds.

This version is already working
I noticed only that: every 11-12 sec the TV stream freezes for 0.5sec while audio stays continous.

Thanks again!

Since I don't own an AV receiver I would like to get some feedback from you on an experimental change I made to audio settings.

1. Download the experimental release (it shouldn't break anything but you can always revert to previous release without wiping your data): https://github.com/kszaq/OpenELEC.tv.../5.0.6-hd-test
2. In audio settings, change both your audio output device and passthrough device to HDMI.
3. Please report if the following work (considering you have an audio setup to handle it):
   • multichannel PCM audio
   • TrueHD passthrough
   • DTS-HD MA passthrough
   • MXQ users: S/PDIF passthrough
4. Please also report regressions in audio if you noticed any.

Thanks in advance for the reports!

Hy,

I set up audio device to hdmi, passtrough device grayed out to hdmi (i didnt use optical), set up speaker config to 5.1
I set up first every hd sound to passtrough.
Then truehd and dts-hd isnt has sound, my receiver displayed unknown source.
The i disable hd audio passtrough, then dts-hd played normal is played downconverted to normal multichannel dts, and dolby hd converted to 2.0pcm 48khz, no multichannel.
I try multichannel audio source too, what is downconverted to 2.0 pcm 48khz..
Thanks Kszaq, this is one step to solution. Dolby hd software decoding to 2.0 already working..
My mxq with every update always better a little.
Thanks again...

Hello,

You image is the best for the Beelink MXQ, but several mpeg2 files are stuttering.
This is an example: https://samples.libav.org/MPEG2/interlaced/burosch1.mpg

Please fix this, if possible.

Many thanks!

Comfirmed.
I try with rpi2 and openelec 5.0.6 too, there is no stuttering, but with wetek and mxq stutter the video.

I try with rpi2 and openelec 5.0.6 too, there is no stuttering, but with wetek and mxq stutter the video.

The reason why there is no stuttering on RPI2 is because the limitations of the RPI2 GPU in that the fps is around 8-9.5 fps rendering it smooth. Where MXQ & MK808B+ uses much better GPU and it playing around 38-45fps and that is why it stutters. MXQ & 808B+ have brill Mali-450 HEVC GPU
