Media Foundation/V4L2 grabber ... (#1119)

* - New Media Foundation grabber - JsonAPI available grabber fix - commented json config removed * Added libjpeg-turbo to dependencies * Fix OSX build Removed Azure Pipelines from build scripts * Remove Platform from Dashboard * Correct Grabber Namings * Grabber UI improvements, generic JSONEditor Selection Update * Active grabber fix * Stop Framebuffer grabber on failure * - Image format NV12 and I420 added - Flip mode - Scaling factor for MJPEG - VSCode (compile before run) - CI (push) dependency libjpeg-turbo added * Refactor MediaFoundation (Part 1) * Remove QDebug output * Added image flipping ability to MF Grabber * fix issue 1160 * -Reload MF Grabber only once per WebUI update - Cleanup * Improvements * - Set 'Software Frame Decimation' begin to 0 - Removed grabber specific device name from Log - Keep pixel format when switching resolution - Display 'Flip mode' correct in Log - BGR24 images always flipped * Refactor MediaFoundation (Part 2) * Refactor V4L2 grabber (part 1) (#62) * Media Foundation grabber adapted to V4L2 change * Enable Media Foundation grabber on windows * Have fps as int, fix height typo * Added video standards to JsonAPI output * Error handling in source reader improved * Fix "Frame to small" error * Discovery VideoSources and Dynamically Update Editor * Hide all element when no video grabber discovered, upate naming * Do not show unsupported grabbers * Copy Log to Clipboard * Update Grabber schema and Defaults * Update access levels and validate crop ranges * Height and width in Qt grabber corrected * Correct formatting * Untabify * Global component states across instances * Components divided on the dashboard * refactor * Fix Merge-issues * Database migration aligning with updated grabber model * Align Grabber.js with new utility functions * Allow editor-validation for enum-lists * Handle "Show Explainations scenario" correctly * Grabber - Ensure save is only possible on valid content * Dashboard update + fix GlobalSignal connection * Ensure default database is populated with current release * Correct grabber4L2 access level * Display Signal detection area in preview * Write Hyperion version into default config on compiling. * Create defaultconfig.json dynamically * WebUI changes * Correct grabber config look-ups * Refactor i18n language loading * Fix en.json * Split global capture from instance capture config * Update grabber default values * Standalone grabber: Add --debug switch * Enhance showInputOptionsForKey for multiple keys * Add grabber instance link to system grabber config * Only show signal detection area, if grabber is enabled * Always show Active element on grabber page * Remote control - Only display gabber status, if global grabber is enabled * WebUI optimization (thx to @mkcologne) Start Grabber only when global settings are enabled Fixed an issue in the WebUI preview * V4L2/MF changes * Jsoneditor, Correct translation for default values * Refactor LED-Device handling in UI and make element naming consistent * MF Discovery extended * Fix LGTM finding * Support Grabber Bri, Hue, Sat and Con in UI, plus their defaults * Concider Access level for item filtering * Concider Access level for item filtering * Revert "Concider Access level for item filtering" This reverts commit 5b0ce3c0f2. * Disable fpsSoftwareDecimation for framegrabber, as not supported yet * JSON-Editor- Add updated schema for validation on dynamic elements * added V4L2 color IDs * LGTM findings fix * destroy SR callback only on exit * Grabber.js - Hide elements not supported by platform * Fixed freezing start effect * Grabber UI - Hardware controls - Show current values and allow to reset to defaults * Grabber - Discovery - Add current values to properties * Small things * Clean-up Effects and have ENDLESS consistently defined * Fix on/off/on priority during startup, by initializing _prevVisComp in line with background priority * Add missing translation mappings * DirectX Grabber reactivated/ QT Grabber size decimation fixed * typo in push-master workflow * Use PreciseTimer for Grabber to ensure stable FPS timing * Set default Screencapture rate consistently * Fix libjpeg-turbo download * Remove Zero character from file * docker-compile Add PLATFORM parameter, only copy output file after successful compile * Framebuffer, Dispmanx, OSX, AML Grabber discovery, various clean-up and consistencies across grabbers * Fix merge problem - on docker-compile Add PLATFORM parameter, only copy output file after successful compile * Fix definition * OSXFRameGrabber - Revert cast * Clean-ups nach Feedback * Disable certain libraries when building armlogic via standard stretch image as developer * Add CEC availability to ServerInfo to have it platform independent * Grabber UI - Fix problem that crop values are not populated when refining editor rage * Preserve value when updating json-editor range * LEDVisualisation - Clear image when source changes * Fix - Preserve value when updating json-editor range * LEDVisualisation - Clear image when no component is active * Allow to have password handled by Password-Manager (#1263) * Update default signal detection area to green assuming rainbow grabber * LED Visualisation - Handle empty priority update * Fix yuv420 in v4l2 grabber * V4L2-Grabber discovery - Only report grabbers with valid video input information * Grabber - Update static variables to have them working in release build * LED Visualisation - ClearImage when no priorities * LED Visualisation - Fix Logo resizing issue * LED Visualisation - Have nearly black background and negative logo Co-authored-by: LordGrey <lordgrey.emmel@gmail.com> Co-authored-by: LordGrey <48840279+Lord-Grey@users.noreply.github.com>
