TV Commands

!! This requires a Rooted TV with SSH access !!

I tested this on my own TV running WebOS 4.9, it may work for other versions but i am not able to test this.

SSH into your TV and run the following commands - THIS IS AT YOUR OWN RISK.

# Test if the endpoint is available to you
luna-send -n 1 luna://com.webos.service.acb/getForegroundAppInfo '{"subscribe":"false"}'

# The response should look like this
{ "returnValue": true, "appId": "cdp-30", "windowType": "_WEBOS_WINDOW_TYPE_CARD", "acbs": [ { "pipelineId": "_Ft70RTmNvefyJe", "playerType": "video", "playStateNow": "playing", "playStateNext": "playing", "isFullScreen": true, "positionX": 0, "positionY": 0, "width": 1920, "height": 1080 } ] }

Credit for figuring out the commands below goes to infowski.

# Create config overrides directory
mkdir -p /home/root/extra-interfaces

# Create config override/addition manifest file
echo '{"service": "com.webos.service.acb","methods": [{"path": "/getForegroundAppInfo","description": "get foreground","requiredPermissions": ["LAUNCH"]}]}' > /home/root/extra-interfaces/com.webos.service.acb.interface

# Enable config override
mount -t overlay overlay -olowerdir=/usr/palm/services/com.webos.service.secondscreen.gateway/interfaces:/home/root/extra-interfaces /usr/palm/services/com.webos.service.secondscreen.gateway/interfaces

# Restart ssap service - the states will be immediately available after this but will not persist when you restart your tv.
pkill -9 -f ss.apiadapter ; pkill -9 -f ss.gateway

# To persist the override add config override to init.d
echo 'mount -t overlay overlay -olowerdir=/usr/palm/services/com.webos.service.secondscreen.gateway/interfaces:/home/root/extra-interfaces /usr/palm/services/com.webos.service.secondscreen.gateway/interfaces' > /var/lib/webosbrew/init.d/override
echo 'pkill -9 -f ss.apiadapter ; pkill -9 -f ss.gateway' >> /var/lib/webosbrew/init.d/override

# Make override executable
chmod +x /var/lib/webosbrew/init.d/override
