Ok... I'll make a new version with detailed logging, as soon as I'm back from vacation.
Does libScreenShot work for you? If yes... how do you invoke it?

I will test it today and will post the command.
I remember I used libscreenshot in the past.
Enjoy your holiday, I will be off next week too so no rush at all
Thank you

This is working libscreenshot syntax for my model

Code: Select all

root@tv:/mnt $ samyGOso -d -T -B -l /mnt/opt/privateer/usr/libso/libScreenShot.s

The image is strange though but I hope will be enough

The same problem with F7000. TV hangs up after executing libAmbiLihgt.
libscreenshot works fine with samyGOso -d -A -B -l /mnt/opt/privateer/usr/libso/libScreenShot.so ALT

Hmmm... that's unfortunate if it only works with the ALT method correctly.
The ALT method grabs the screen as a compressed JPG. This means that the pixel information isn't directly accessible, instead it needs to be decoded, which isn't that easy.

This project sounds very cool :)

Till now I use Hyperion on RPi with an Video Grabber on my TV for Ambilight (WS2801 LED). But I've no Ambilight when I use e.g. Plex-App or something else :(

Therefor I have some questions for realize your Ambilight-Project on my TV (UE75H6470).
1.) Will Ambilight work with any Content (e.g. Apps, or Movies from Blue-Ray)
2.) Do I still need other Hardware then ESP8266 and LED's (WS2801). WIll LED's connected directly to ESP8266? Maybe write answer to Post1 :)
3.) Yesterday I've downgraded my TV (firmware T-MST14DEUC from 2880.2 to 0000) and installed SamyGo on it (https://forum.samygo.tv/viewtopic.php?f=75&t=10919). After that I could connect with WinsCP on my TV. But folder "/mnt" is empty on my TV. So where should I place your lib's?

Thx for help :)
My TV's: UE50H6470 and UE75H6470

Yes, it should work with every content, I don't have it working but it using libscreenshot which can capture everything.

You don't need any extra hardware my setup is similar to yours I am using lightberry hardware and I attached it directly there.

I've an NodeMCU V3 on my desktop, but I don't know on which Pins I should connect CK and DI of my WS2801 LED.
