[App] libYTAdblock H

[370network]

Youtube adblocker for H series, can be also used as a general loader for userscripts into widgets.

Notes:

• Has only been tested on H MST
• The adblocking javascript is injected into every widget, but that shouldn't cause problems (there is an if statement to execute only if the url is www.youtube.com)
• Adblocking code is from https://github.com/webosbrew/youtube-webos

Usage:

• First install modded YT app, by extracting the zip and moving it to /mtd_rwcommon/widgets/user, unfortunatelly it doesn't seem to load properly into the stock one (seems to not act as a normal widget), as a bonus you will get 1080p UI and video playback (stock is all 720p)
• You will need samyGOso
• Copy libYTAdblock.so into /mnt/opt/privateer/usr/libso
• Copy 99_95_YTAdblock.init into /mnt/etc/init.d to autostart or load manually with

  Code: Select all

  samyGOso -l /mnt/opt/privateer/usr/libso/libYTAdblock.so -n WidgetEngine 

• IMPORTANT: After loading up youtube, open settings and close with return to load the script, a popup will appear on screen to inform you it has been loaded, do it everytime you open youtube

Caution:
The code is probably not of particularly high quality, I'm not very experienced with this sort of stuff. There are definitely better ways to implement it. It contains static offsets, modifies instructions, writes to read only memory... It shouldn't break the TV, it doesn't write anything to storage, but proceed with caution mainly if testing on other tv models.

20/10/2024: Updated script with new code from original openlgtv adblocker, should work on YT as of now

H series is old, but YT still works and I hope someone will get some use out of this, if it works for you, let me know. Thanks.

[Stefan244]

Thank you very much - it works for me

I have a Samsung H6400. Having root, SamyGOso running fine.
Installed YtMod I can see the app installed on the UI and can run it.
I installed libYTAdblock.so and the init script from the attached zip. Seems the "so" is loaded fine.

Code: Select all

# cat /dtv/InjectJS.log

When I load the modded youtube app and go to the settings, I hit the return button but it doesn't pop up anything. What can be the issue? Should the Youtube app language be english or any other language should work as well ?

Did youtube change the code and this piece of SW requires an update??

Shall I uninstall the stock youtube app or can I leave it installed?

Language should not matter, you can keep the stock yt app just launch the new one, popup should show even if youtube broke the blocking.

Could you please try this:
First start the tv, but do not load the so
Then ssh or telnet in and run:

Code: Select all

pidof WidgetEngine

It should return a number (or look up the pid using ps)
Then run:

Code: Select all

gdb -p <THE NUMBER YOU GOT>

You should get into a shell with (gdb) on the start of the line, there run:

Code: Select all

x/4b 0x4A104FB8

It should spit back something like this

Code: Select all

0x4a104fb8 <_ZN9CWEWidget17GetWidgetEventStrEPcS0_S0_iS0_+324>:	0x1c	0x12	0x9f	0xe5

Also please try:

Code: Select all

x/s 0x4A15E3EC

Did it output this?

Code: Select all

var weEvent = new WidgetEvent();

Let me know if this worked.
When you are done just turn off the tv with the remote.

And sorry for the late reply i didn’t have notifications on the topic, fixed that now

[xray99]

I really appreciate your reply.

I tried what you suggested.

1st I disabled the load of the so by removing the executable permission of the init script.

Code: Select all

# ls -ld /mnt/etc/init.d/99_95_YTAdblock.init
-rw-------    1 root     root           614 Jan  1 00:05 /mnt/etc/init.d/99_95_YTAdblock.init

Then powered off the TV with remote and started again so that the libYTAdblock so is not loaded.

Executed your commands.

When the library was loaded I got pretty much the same output.

This is the output when the library is loaded:

Sorry for making this debugging such a long winded process but I kind of forgot how all this stuff worked and have to scrape together the info i have.

Please try running "info sharedlibrary" in gdb and send me the output (same steps as before)

Also could you please try finding the "WidgetEngine" binary and the "libWECore.so" binary on your tv (sorry I cannot tell you the path, i do not have the tv on hand) and getting a sha checksum of them? I'd like to know if they are identical to mine.

Firmware version is: T-MST14DEUC-2900.0 if it matters.

I have both stock and modded YT app installed.

[370network]

aight this is weird the files are different, maybe different fw? I am on i think T-MST14DEUC_2130.0 with skype refueled root or something like that. You could try sending me the WidgetEngine and libWECore.so (from /mtd_exe/) and i could try and take a look at them

[xray99]

Hi,

Both files attached. Both from directory: /mtd_exe/WidgetEngine/

[370network]

please try this
