set_picture_mode() method doesn't work

[chros73]

Hi Josh!

Thanks for adding these new methods!
set_current_picture_mode() works fine here: aiopylgtvcommand 192.168.1.78 set_current_picture_mode expert2
But not set_picture_mode(): aiopylgtvcommand 192.168.1.78 set_picture_mode expert2 hdmi2_pc

Basically, I try to switch to the same preset but into PC mode from non-PC mode. Does it work for you?
Thanks

TV: LG B8, fw 4.10.25, webos 4.1.0-5511

This function cannot actually switch between pc and non-pc mode. What this function call will do is change the picture mode in the pc mode. So if you call that and then manually change hdmi_2 to pc-mode, then you should find that the picture mode has been set to expert2.

I'm not aware of exactly how to automatically change between pc-mode and non-pc mode (but it's likely possible by manipulating other settings through similar api calls)

[chros73]

I see, and indeed works like this, thanks.
Let us know if you manage to figure out switching between PC and non-PC mode :)
(set_current_picture_mode is really handy for comparing image: no need for fool around with UI elements, that modifies the image, especially with HDR10/DoVi content, thanks for this!)

1 more question, how can I use set_current_picture_settings() via command line? I tried these but didn't do anything:

aiopylgtvcommand 192.168.1.78 set_current_picture_settings "\"brightness\": \"75\""
aiopylgtvcommand 192.168.1.78 set_current_picture_settings "brightness: 75"
aiopylgtvcommand 192.168.1.78 set_current_picture_settings "{"brightness": "75"}"

I don't think you can do that using the command line.

Everything is possible from a python script :)

[chros73]

Yes, you are right, not by default, but it can be achieved by passing dictionary via JSON string (although dunno how to automate this for every argument, maybe checking that argument string starts and ends with { ?)
This would be a nice addition, if it can be done.

And thanks, it works from a script well:

import asyncio
from aiopylgtv import WebOsClient

async def runloop():
    client = await WebOsClient.create('192.168.1.78')
    await client.connect()
    settings={"brightness": "75"}
    await client.set_current_picture_settings(settings)
    await client.disconnect()
asyncio.run(runloop())

For changing pc mode I THINK it would be something like

        uri = "com.webos.settingsservice/setSystemSettings"

        params = {"category": "other", "settings": {"hdmiPcMode": {"hdmi1" : False, "hdmi2": True, "hdmi3" : False, "hdmi4" : False} }}

        await client.luna_request(uri, params)

[chros73]

Thanks, but it doesn't seem to do anything (non-PC HDMI2 input is selected).

[bendavid]

Yah unfortunately this method of accessing the settings can't return any error messages, so it's a bit difficult to debug.

[chros73]

Actually the PC mode trick works! :)
I just added another PR for it, thanks!

[chros73]

I updated the PC mode PR to only apply to the selected HDMI input.
