@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.

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...

@Stefano i tested it now , yes there is no sound in ear speaker and high speaker

@Stefano really can't test it now, my earspeaker is dammaged, can't found it her in my country, maybe will command it from aliexpress. but i tested last week and work but sound is very low, must change some xml config file to increase sound.

@Stefano call work i tested it. Also got camera work 50%, photo 16mb , but can't record video

for LGV20 don't support all fastboot command like flash and boot, so all time i use TWRP to flash halium-boot.img.

@UBportsNews
