Interesting DV

netflix issue is because it relies on inputstreamhelper. ishelper by default responds with widevine not available on aarch64.
There should be a new version of ishelper soon

Widevine AARCH64 now available

64bit ARM Linux Widevine CDM now out in the wild :slightly_smiling_face: @tmm1 …found it. looks like was just released last month in a new 64bit beta chrome os " seems new development https://groups.google.com/a/chromium.org/g/chromium-os-dev/c/GdZ0mebutXw inside https://gsdview.appspot.com/chromeos-localmirror/distfiles/chromeos-lacros-arm64-squash-zstd-112.0.5579.0 " i managed to open the above squash-zstd file in windows using an extended version of 7zip: https://github.com/mcmilk/7-Zip-zstd tmm1 said its not working in the arm64 build of LibreELEC due to "libwidevinecdm.so: undefined symbol: __aarch64_ldadd4_acq_rel" but the LibreELEC guys are looking into it inputstream helper will need to add support for this. Not sure if there is any recovery image that contains it yet. Unless there is a Beta channel recovery. Looking for Acer Chromebook Spin 13 (CP713-1WN) on Chrome version 112 Current "Stable" seems to be chrome 109 UPDATE: "LE folks got aarch64 widevine working! Might require some glibc patches, will see how it shakes out"

You can comment out a line in inputstream helper and it won’t check aarch. So Netflix works in aarch64, just tested on vim4.
There’s a comment in that GitHub link that explains how to do it.

@Vasco

Just installed 21 nightly on my S905X4 device and can confirm both Disney+ and Netflix work with the new 64 bit widevine cdm provided with Disney+ addon by matthuisman
To make Netflix work, you have to go to inputstream helper addon Settings → Debug → Disable Inputstream Helper.
With that setting, Netflix plays fine. No need to edit inputstream helper code

So its even easier now, I did this last week and definitely followed the difficult route.

crazyturk · 22 March 2023 08:14

Thanks, I applied what you said is okay.

Portisch · 22 March 2023 08:23

The correct fix is to add aarch64 here:

github.com

emilsvennesson/script.module.inputstreamhelper/blob/master/lib/inputstreamhelper/config.py#L38


      
              'aarch64_be': 'arm64',
              'AMD64': 'x86_64',
              'armv7': 'arm',
              'armv8': 'arm',
              'i386': 'x86',
              'i686': 'x86',
              'x86': 'x86',
              'x86_64': 'x86_64',
          }
          
          
WIDEVINE_SUPPORTED_ARCHS = [
              'x86_64',
              'x86',
              'arm',
              'arm64'
          ]
          
          
WIDEVINE_ARCH_MAP_X86 = {
              'x86_64': 'x64',
              'x86': 'ia32'
          }

Did you try on the new ce 21 build?

Portisch · 23 March 2023 08:42

new nightly 20230323 does now work on this box?
media playback does work?

dmesg | paste and
journalctl -l | paste

djnice · 23 March 2023 09:21

Yes, it works, media playback too.

djnice · 23 March 2023 09:24

Yes, I tried, but unfortunately it still restarts the box.

djnice · 24 March 2023 10:14

@Portisch
depmod: ERROR: failed to load symbols from /lib/modules/5.4.180/dovi.ko: Exec format error
insmod: ERROR: could not insert module dovi.ko: Invalid module format
kernel: Module has invalid ELF structures

vermagic=5.4.180-06098-gbf383614f96a

Is there still a difference between the two kernel versions?

Portisch · 24 March 2023 10:43

First item would be a Android dmesg log.

djnice · 24 March 2023 11:44

How do I query it? Don’t I need root access?

frodo19 · 24 March 2023 13:38

In my homatics box, the last omega nightly works, play fine all my media. No ceemc popup issue.

Adam86 · 24 March 2023 19:20

Just trying to understand the last several posts, has there now been some progress on CoreElec now supporting DV/Dolby Vision on the latest nightly builds?

selfcontained · 24 March 2023 21:46

There has been some overlap in the posts of this thread - but from my read, no CoreELEC build can play Dolby Vision HDR files of any profile (7, 8.1, nor 5).

frodo19 · 25 March 2023 05:58

Today still…

Borec1 · 25 March 2023 10:24

If vermagic is checked, the Kernel would have to be built exactly according to the original. Which I doubt is possible. But vermagic can be changed during compilation, I already have some experience with it from other distributions.

So it should be possible to build the CE to match the vermagic hash and then it should be possible to upload dovi.ko

vpeter · 25 March 2023 10:30

How was this dovi.ko obtained? Copying from running Android?

rome1931 · 25 March 2023 11:58

It was extracted from a firmware image I shared.
