* aja: Initial commit of AJA capture/output plugin * aja: Fix clang-format on aja-output-ui code * aja: Remove script used during dev/testing * aja: Address pull request feedback from @RytoEX * aja: Remove the SDK sources and update CMakeLists to point to new headers-only/static libs dependency distribution. * aja: Only build AJA plugin on x64 on macOS for now * aja: Remove the non-English placeholder locale files. The english strings/files will be produced via crowdin, according to @ddrboxman. * aja: Add FindLibAJANTV2.cmake script to locate the ajantv2 headers and static libs in the OBS external deps package(s). Tested on Windows x64. macOS and Linux x64 TBD. * aja: Add ajantv2/includes to FindLibAJANTV2 include search paths * aja: Remove commented code from aja CMakeLists * aja: Remove debug code and comments that are no longer needed. * aja: Fix indentation * aja: Remove disablement of clang-format in routing table and SDIWireFormat map * aja: Use spaces for all indentation in widget crosspoint arrays where we disable clang-format * aja: Address code style comments made by @RytoEX * aja: Fix uneven indentation * aja: More fixes to if/else placement and remove superfluous comments. * aja: Rename 'dwns' to 'deactivateWhileNotShowing' for clarity. The DeckLink plugin still uses the variable name 'dwns' and should be changed, if desired, in a separate PR. * aja: Remove X11Extras dependency from AJA Output frontend plugin * aja: Add patch from Jim to find AJA release/debug libs * aja: Improve AV sync of queued video/audio sent to the AJA card in the AJA Output plugin.
