PicCap - Hyperion Sender App | Ambilight for LG WebOS TVs

Hello, i have piccap working with hyperhdr-webos working. But i dont know why it has some kind of 'lag' (0.5ms) when displays the colors.

My LG info is:

"board_type": "K5LP_ATSC",

"hardware_id": "HE_DTV_W19P_AFADATAA",

"product_id": "43UM7360PSA",

"core_os_release": "4.9.7-17",

"webos_manufacturing_version": "05.30.40"

And my hardware is a esp8266.

When i use hyperion from my pc and use the capture monitor config, the lights works like a charm.

Also if i try to connect the piccap to my pc hyperion, it detect as flatbuffer server (i know this is ok) but the lag is still there.

Any suggest?

Thanks, regards.

nvm, i solved it through ethernet cable on the tv. Seems i have some wifi issue.

Thanks!

Hello,

I'm currently looking into switching my Ambilight setup, which is currently still running on a discontinued "Dreamscreen" solution via scaler on the 2nd HDMI output of my AVR, to a WebOS+Piccap+ESP32WLED solution.

The only limitations I have at the moment are that of course no internal TV works with Ambilight and externally fed HDR is displayed with pale colors on the Ambilight.

This is my question: Since both SDR and HDR content is displayed via the TV, is this automatically recognized/considered somewhere in Piccap or in Hyperion or in WLED or do I have to change a setting manually in one of the programs depending on the SDR/HDR/DV picture mode so that the LEDs show the same good colour reproduction?

I once had an insight into an implementation with HyperHDR, which had a tone mapping function that I believe had to be switched On or Off depending on the SDR or HDR content, or had to be triggered via a script.

Surely there is already more successful experience with Piccap here!

hallihallo

i am running piccap 0.23 on a LG OLED C9 and would like to update to current 0.43 piccap.

in the past i have tried updating the backend only to test out new versions of hyperion-webos but the results were never as good as the old version (which is not w/o issues either)

so my question:

Is anyone running latest piccap (+ latest backend) on a B9/C9 successfully and could share settings (quirks) ?

That'd be much appreciated. thanks!

pclin Hi

I appreciate all the responses you have provided and cleared so many of my questions.

I have the LG OLED65C9PTA, running the latest OS 05.40.45. I used the dejavuln method via USB to root the TV, it worked and I had Homebrew installed, activated SSH, File system and restarted.

I then tried to install PicCap, but that through a huge error, something to do with github, I could not read it (should have taken a picture) but it disappears after a couple of seconds. So PicCap intall failed.

I then downloaded the PicCap ipk file and used scp to intsall it. that gave an error:

Installing org.webosbrew.piccap (0.4.3) on root.
Collected errors: * verify_pkg_installable: Only have 0K bytes available on filesystem, needs 1759K bytes * opkg_solver_install: Cannot install package org.webosbrew.piccap.
root@LGwebOSTV:/tmp#

So then I ran the command

rm -rf /tmp/*

to clean up and get some space.

After that I tried again.

Collected errors: * file_mkdir_hier: Cannot create directory /var/run': File exists.
 * opkg_lock: Could not create lock file directory /var/run: File exists.

I then put the ipk file on a usb and coped it to /media/internal folder and tried to run if from there. Same errors as above and finally I tried:

rm -rf /var/run 
ln -s /media/internal/var/run /var/run
opkg install ./org.webosbrew.piccap_0.4.3_all.ipk

This failed too.

Installing org.webosbrew.piccap (0.4.3) on root.
Collected errors: * verify_pkg_installable: Only have 0K bytes available on filesystem, needs 1759K bytes * opkg_solver_install: Cannot install package org.webosbrew.piccap.

So, I gave up and went over to the TV to Restart. The TV was very laggy and after restart all I got was a black screen with nothing on it. It is on, but nothing on the screen. SSH does not work either.

I do not know what went wrong above and how to fix it now.

Any help is appreciated.

All I wanted was to setup PicCap, Hyperion on the TV itself to enjoy my ambient light without the troublesome grabber and RPi.
