PicCap UI not working on 3.4

[willscottuk]

Hi,

Carrying on from some of the Discord chat over the weekend - now that hyperion-webos is fixed for 3.4.0 / the M16_DVB board.

While the UI loads, root status never loads, nor is the UI able to save or load configuration, or start/stop the service.

The only functioning button is the "Reboot TV" button.

"board_type": "M16_DVB",
"hardware_id": "HE_DTV_W16N_AFADABAA",
"product_id": "49UH750V-ZA",
"core_os_release": "3.4.0-5908",
"webos_manufacturing_version": "05.60.25"

WebOS homebrew 0.4.0 installed, root reported as "ok" in homebrew.

Note: service is launched when called and elevate-service is properly executed, but calls still error out with Denied method call for category {}...

We probably need some extra patching in /var/palm/ls2-dev.

From a newbie prospective, i can confirm that the issue is strictly ui related. I took a look to the script.js file and tried the various calls and they are all working correctly:

luna-send -n 1 -f luna://org.webosbrew.piccap.service/isRoot '{}'
{
    "rootStatus": true,
    "returnValue": true,
    "backmsg": "Running as root!"
}

luna-send -n 1 -f luna://org.webosbrew.piccap.service/isRunning '{}'
{
    "returnValue": true,
    "isRunning": true
}

still, from the ui, the situation is what @Informatic already described.

For now i started the service using luna-send -n 1 -f luna://org.webosbrew.piccap.service/getSettings '{}' to get the json config. Modified as needed a set with luna-send -n 1 -f luna://org.webosbrew.piccap.service/setSettings '{"returnValue": true, "backend": "l ibdile_vt", "port": 19400, "width": 360, "height": 180, "captureUI": true, "ip": "192.168.1.26", "fps": 0, "backmsg": "S ettings got successfully!", "captureVideo": true, "autostart": true}'

then with luna-send -n 1 -f luna://org.webosbrew.piccap.service/start '{}' the service started with no problem

as said, the ui is still stuck with "Root status: Loading status..." and with the buttons not working returning the message @Informatic already reported so that will definetly need a fix.

@PaoloVallesi Thanks so much for the info on starting it via luna-send. I managed to get it working, but the backlights only display white light, which dims and brightens according to the scene. I have an Nvidia Shield with the Hyperion Grabber installed that works perfectly well with colour. Any ideas why colour isn't working with the LG implementation?

Hello. My WebOS 3.4 have same bug. I am send this settings, but service not start

# luna-send -n 1 -f luna://org.webosbrew.piccap.service/setSettings '{"backend": "l ibdile_vt", "port": 19400, "width
": 360, "height": 180, "captureUI": true, "ip": "192.168.0.168", "fps": 0, "backmsg": "S ettings got successfully!", "c
aptureVideo": true, "autostart": true}'
{
    "returnValue": true,
    "backmsg": "Settings set successfully!"
}

Then I am try to start, I am get error

# luna-send -n 1 -f luna://org.webosbrew.piccap.service/start '{}'
{
    "returnValue": true,
    "backmsg": "ERROR: Capture main init failed!"

For me there was a small mistake in "backend" section (only a whitespace to much). I've added a fix for me in "width" so probably you should edit this.

This one worked for me:

luna-send -n 1 -f luna://org.webosbrew.piccap.service/setSettings '{
    "returnValue": true,
    "backend": "libdile_vt",
    "port": 19400,
    "width": 320,
    "height": 240,
    "captureUI": true,
    "ip": "XX.XX.XX.XX",
    "fps": 0,
    "backmsg": "Settings got successfully!",
    "captureVideo": true,
    "autostart": false
}'

And to Start and Stop :

luna-send -n 1 -f luna://org.webosbrew.piccap.service/start '{}'

luna-send -n 1 -f luna://org.webosbrew.piccap.service/stop '{}'
