[General] Some (newer?) TVs: Checking the power state via luna:https://com.webos.service.tvpower/power/getPowerState and evaluating "state" for "Active"/"processing" and pausing capturing due to that criteria, to detect power state, causes flickering each 2 minutes.

This shows up randomly and leads to hyperion-webos switch off/on:
{ "returnValue": true, "state": "Active", "processing": "Request Screen Saver" }
{ "returnValue": true, "state": "Active", "processing": "Screen On" }
{ "returnValue": true, "state": "Active" }
I have a C7 device and when the TV goes into screensaver the screen grabber does not work afterwards.
Stopping and restarting the service is not working and a full tv reboot is needed.
[DILE_VT] TVs of C9 series: If
DILE_VT_Create
function is called first, initialization ofDILE_VT
will fail most of the cases.Solution: Call
DILE_VT_CreateEx
beforeDILE_VT_Create

[DILE_VT] 4k content on some webOS 4.3.0 devices will be cropped to 1/4 of the picture when captured from

.Solution: Use (not-named) value

to pass asdump_location
toDILE_VT_SetVideoFrameOutputDeviceDumpLocation
