jernej Hi, can you compile new images with corrected? as well as to build the image of the addon pvr ...

Corrected what?

About iptvsimple: I generally don't support anything regarding addons, so I won't do that (too much other work). You can always build it yourself by intructions provided in FAQ. Besides, you linked code which is meant to be compatible with new, work in progress, Kodi 18. This OpenELEC is using Kodi 16 and I'm almost sure that it won't be possible to compile it directly, without any modifications.

It seems CEC not working with any LG tv. Not even recognized and that's end the story. I can't remem ...

I just found following two issues, which implies LG is hard to get working:

Unfortunatelly, driver does some signaling on it's own. It may well be by standard, but not compatible with LG SimplLink. To fix this I would need LG TV, which I don't have...

I try to compile, but when I tried it, it is compiled under Ubuntu and have not worked on openelec, due to the dependency problems

Philips TV on the same problem, I think they use something very similar with lg

OpenELEC has minimal tool requirements to build it. Especially on Ubuntu it should automatically propose what to install if you don't have everything. Only exception is device tree compiler (dtc), because it is specific to H3 project, but that is still easy to install with apt-get.

Unless you know how to fiddle with kernel drivers source, you can't, unfortunatelly.

You say you need an LG TV to fix the CEC bugs. Are extensive logs not sufficient to do that?
Over on the ODroid C2 forum they are building LibreELEC for the C2 (created by wrxtasy).
They too have had problems getting CEC to work properly yet they came very far.
Maybe they are willing to help you or point you to a source which you can easely implement.

Actually, they even got official support for LibreELEC because of their combined efforts.

Maybe you can too with their help!

WMV1, WMV2, VP6 and VP9 codecs, although supported by CedarX, are SW decoded (nothing can be done to improve this)

what about wmv3?
software decode or HW or not supported
I know wmv3 is not playable
no error message
debug message says wmv3
It recognize wmv3
what happens inside?

reading DVDVideoCodecCedarX.cpp
I find wmv3 treated in almost the same way as wmv2 wmv1

Over  ...

There are many obstacles:
1. Allwinner doesn't provide any kind of information about CEC HW, so driver is based on reverse engineering and even on guessing (blind trial and error).
2. I currently don't own any kind of HW which is CEC capable (not even a TV). I will get soon HDMI audio splitter, which might support CEC.
3. Remote debugging doesn't work, unless issues are trivial. Here issues are not trivial and I don't have full understandment what is going on (check points above).
4. I won't never ask to accept this into LibreELEC. Kernel code and CedarX libs violate GPL license. There is no redistribution license for Mali driver. H3 support in Kodi is naive at best and it has a lot of issues. Most issues are/will be addressed in mainline kernel. With current state it would be already possible to make working image with SW decoding (still with Mali redistribution issues). I expect that mainline kernel will be capable of HW decoding in a year or two (MPEG1, MPEG2 and partially MPEG4 already works for A10/A20 with patches).

I'm looking into it. WMV3 is threated completely different than WMV1 and WMV2. Don't let few lines of code difference to confuse you.
