is it a possible to add sypport for WebOS 1-2?

[PaveLGIL]

I have root access on my TV, and Homebrew installed. PicCap also installed, but not all setting available for me..
Is it a possible to add 1-2 WebOs versions support?

[Informatic]

Yeah, this is fairly likely. You'll need to SSH onto the TV and try running hyperion-webos via CLI to check if it's just the GUI that's broken. For example like this:

/media/developer/apps/usr/palm/services/org.webosbrew.piccap.service/hyperion-webos -S --verbose --backend libdile_vt --address 10.2.3.4 --fps 30 -x 192 -y 108

[PaveLGIL]

Sure, will try! Thank you!

[PaveLGIL]

Unfortunately see ./hyperion-webos: /lib/libc.so.6: version `GLIBC_2.17' not found (required by ./hyperion-webos)

[PaveLGIL]

Could you please help me install this lib? Or maybe you can tell me where I can find instruction for it..

[Informatic]

This should probably be fixable fairly easily by rebuilding hyperion-webos using a toolchain that uses older glibc. (eg. this one → https://github.com/openlgtv/buildroot-nc4/releases/tag/webos-0d62420) You generally can't "upgrade" glibc on the TV itself.

[PaveLGIL]

Oh.. I really sorry, but, could you please share short instruction for me? How can I do this?

[PaveLGIL]

I really need help on it.. If you can provide any help, I will be really appreciated..

[Informatic]

I will try to make a test build for you tonight.

Thank you, so much! Will wait)

[Informatic]

Download and extract contents of this package to /media/developer/apps/usr/palm/services/org.webosbrew.piccap.service
hyperion-webos-092b13c-buildroot.tar.gz and test again

[PaveLGIL]

Thank you so much! It is look really better)
But have one more error(

hyperion-webos: symbol lookup error: /media/developer/apps/usr/palm/services/org.webosbrew.piccap.service/libdile_vt_backend.so: undefined symbol: DILE_VT_GetVideoFrameOutputDeviceLimitation

[Informatic]

Oof. I am assuming you are running webOS 1.x?

On webOS 1.4.0
--------
File libdile_vt_backend.so:
Missing symbol: clock_gettime
Missing symbol: DILE_VT_GetVideoFrameOutputDeviceLimitation
Missing symbol: DILE_VT_SetVideoFrameOutputDeviceDumpLocation
Missing symbol: DILE_VT_SetVideoFrameOutputDeviceOutputRegion
Missing symbol: DILE_VT_Start
Missing symbol: DILE_VT_Stop
Missing symbol: DILE_VT_WaitVsync
Missing symbol: log_printf
Indirectly referencing: pthread_create
Indirectly referencing: pthread_join

That's not great, since these symbols are fairly crucial here (eg. DILE_VT_SetVideoFrameOutputDeviceOutputRegion is used for downscaling, and DILE_VT_WaitVsync is used for frame keeping), and I am not sure if we will be able to make it work on 1.x.

[PaveLGIL]

Oohh..(( Got it..( Thank you for your help.. I really appreciate it! Really big help from your side.. If nothing else can be done, write me please, I will close the task. Thank you again!

[PaveLGIL]

So, should I close this task? Or is there something else that can be done?)

[Informatic]

Not at this time. If anyone wanted to do some research around this themselves - feel free, but considering how little webOS 1.x users we have (since we don't have any user-friendly exploits there), I am not planning on working on this further, sorry :(

[PaveLGIL]

Got it) Thank you, so much!)

Got a similar Problem running webos 1.4 Afro Ashley which cant be upgraded.
Root Status is OK but cant find a Piccap Version which is displayed correctly. Can only See half of the UI screen Plus its frequently checking on root Status trying to evaluate the Status. Would be very nice If there would be a compatible Version for my TV.

[smx-smx]

I did some analysis not long ago, and the missing symbols are implemented in RELEASE/tvservice in older versions. This complicates the interactions because IPC or injection is required.

It's not impossible but needs a non negligible amount of work, and i don't have a device i could use to test
