@jiho nice
the audio call not work, also fingerprint.
I'm working now to fix this issues

@jiho can you reboot to recovery twrp,

Then :

adb shell
ls /data

verif if android-rootfs.img & rootfs.img exists

Also can you give me the log under
/data/system-user/var/log

Also you must format data partition before install to remove any encryption

@jiho thanks
Did you installed vendor.img?
There is twrp install file which more simple and it install all needed files

Issue:

• for wifi you must wait few seconds
• for camera, first boot maybe will not work (permission missing), so reboot phone after setup it.

@unklebonehead you have h918 variant ? if yes you can't install twrp by adb , you must use lafsploit .

@unklebonehead you can install using twrp.

@unklebonehead i will upload new version bugs fixed : camera.

@Guf said in Ubuntu Touch on LG G6 (h870 model): call for testers:

Annoying flooding of errors in dmesg with the following message: "IPC_RTR: msm_ipc_router_bind: pm-service Do not have permissions" . It unfortunately drains battery

Hi i have ported LG V20, same hardware and manifacture. for this error

Annoying flooding of errors in dmesg with the following message: "IPC_RTR: msm_ipc_router_bind: pm-service Do not have permissions" . It unfortunately drains battery

Didi you added SECURITY_ANDROID_GID_CAPABILITIES in your kernel ?
see this
http://docs.halium.org/en/latest/porting/debug-build/wifi.html

I removed both minimediaservice & miniafservice, camera don't work, got "Camera service not found", but the driver is loaded correctly and system detect 3 cameras.

I think there is problem in sensor or sound, because got many errors in logcat.
Also why /data/misc/media is empty, there is no media_codecs_profiling_results.xml.

@peat_psuwit
Yes, android_getCpuFeatures i fount it builded in halium (libskia.so)
and i added libskia.so to libbwfocuspeaking.so

patchelf --add-needed "libskia.so" lib/libbwfocuspeaking.so

Also i updated camera libs , got camera work.
BUTTT
Make photo work , not very good, but i can take photo.
Video record no. I will investigate it more and return to you for HELLP
Best Regards and thankouy

@peat_psuwit
i'm tried to remove the dependcies i ran this command

 patchelf --remove-needed "libjnigraphics.so" vendor/lge/v20-common/proprietary/lib/libfilm_emulation.so

got this error

E HAL     : dlopen failed: cannot locate symbol "android_getCpuFeatures" referenced by "/system/lib/libbwfocuspeaking.so"...

This method android_getCpuFeatures i think its part from android NDK
Edit : i found it in libskia.so extracted from stock rom

nm -D libskia.so |grep android_getCpuFeatures
002ffca8 T android_getCpuFeatures

@peat_psuwit Thankyou very much for your reply
First note is camera.msm8996 driver can't load without added libjnigraphics.so, libandroid-runtime.so and 17 others blobs files. I extracted them from cm-14.1 rom and added it to my system.img to make driver HAL camera happy and load.
I tried remove dependencies with patchelf but not work (got methods unknown errors).

Second note :i tested camera with gst-inspect-1.0 got this error

**
ERROR:gstamchybris.c:1286:scan_codecs: code should not be reached
**
ERROR:gstamchybris.c:1286:scan_codecs: code should not be reached
No such element or plugin 'androidmedia'

With droidmedia logcat show me this

ServiceManager: add_service('SurfaceFlinger',9) uid=1000 - ALREADY REGISTERED, OVERRIDE
ServiceManager: service 'SurfaceFlinger' died
ServiceManager: add_service('media.player',10) uid=1013 - ALREADY REGISTERED, OVERRIDE
ServiceManager: service 'media.player' died

Thats why i used old camera_service with no hope to make video record work.

@peat_psuwit said in How to: test GStreamer-droid based camera support in Ubuntu Touch (for Halium 7.1 based port):

ps ax -H

The device is LG V20 tmo h918 based on halium-7.1 and i used stock kernel for nogat 7.0
ps ax -H : https://paste.ubuntu.com/p/bF2t6MgwQZ/
Also i added camera_service in init.qcom.rc to force start media record
service camera_service /system/bin/camera_service
class main
user media
group audio camera

This is error in logcat
https://paste.ubuntu.com/p/7rdQg83CbP/

@peat_psuwit i tested it and video record not work got this error

ServiceManager: Waiting for service android.media.IMediaRecorderFactory...
