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.
Got the same problem with crashing my TV. Just only working with ALT method.
Any chance to get this working for ALT method?
EDIT:
Found some example code for jpeg decompression in memory with jpeglib.
Maybe it's possible to implement that jpg decompression with ALT method to get the color information back.

Still I need Wlan on my ESP8266? And if, why?
Because I have trouble to connect with WinSCP everytime I put in my NodeMCU because it takes the same IP-Address of my TV.
I'm waiting for my WS2801 from Aliexpress because I first wanna try on my small TV in bedroom before I change everything in Livingroom.
Will Ambilight start when I put my TV on or do I have to make anything else?
Thx for your help

You need network connection because your TV will send requests to node mcu. To avoid ip address conflicts you can set up dhcp static address alias for NodeMcu from your router.
Before buying anything make sure your TV is H series because it seems is the only one which is confirmed to work with this lib.

@bobiturboto
Thx
I have two H-Series (UE50H6470 and UE75H6470). I've bought them because of this I only have to make one Channellist and I've needed Scart for Ambilight in Livingroom. And after I've read this thread I bought the WS2801 again
You need network connection because your TV will send requests to node mcu.
Normally my TV is connected with Lan and not over WLan because signal in Bedroom is weak. Do I have to use only WLan?

For NodeMcu you have no choice because it has only wlan. For the tv it doesn't matter my is connected by LAN too

Yesterday I've tried to make Screenshots as well for testing.
Here are my Results:
Code: Select all
samyGOso -d -T -B -l /mnt/opt/privateer/usr/libso/libScreenShot.so JPG
No Picture, TV freezes
Code: Select all
samyGOso -d -A -B -l /mnt/opt/privateer/usr/libso/libScreenShot.so ALT
Perfect Picture
Code: Select all
samyGOso -d -T -B -l /mnt/opt/privateer/usr/libso/libScreenShot.so
Picture is upside down

Can we use the same approach like for J series

Hey... that looks promising... I am going to take a look at it at some point. I hope it works
Thank you for your research and your hint.

Since this works, you're good to go. Don't worry about the upside-down picture. The only important thing here, is that we get pixel data. You can ajust the pixel direction in the libAmbilight params.
