Qt5X11Extras (QX11Info) was added in

actually be used. Qt6 doesn't yet ship X11Extras, so let's remove it.

This also modifies libobs.

This adds the ability for scene items to have transitions
when their visibility is toggled.

obs-ffmpeg: Align both NVENC implementations

Add function size_t obs_source_get_filter_count(obs_source_t *source)
which returns the number of filters a source has. Update docs for it.

Fix various warnings about variable size.

If the preset specifies the lookahead length, use it. Force to previous
setting of 8 otherwise.

Hard-code various config values as they appear in FFmpeg.

Compute buffer count according to FFmpeg logic.

Force-enable lookahead if nvEncGetEncodePresetConfig says to.

Plumb Psycho Visual Tuning setting into fallback encoder.

Set vbvBufferSize to match FFmpeg behavior.

If Psycho Visual Tuning is on, switch aqStrength to from 0 to 8 to match
FFmpeg default.

Don't set maxEncodeWidth/maxEncodeHeight since FFmpeg doesn't, and we
don't support resolution changes.

Multiply by number of bframes like FFmpeg does.

For example, 1920:1080 becomes 16:9.

This moves X11 platform to the qt private functions, as x11info was
removed from Qt6 so this is required for a clean Qt5/6 transition.

This is the implementation of x11info::getdisplay so it should still
work on older platforms. This "API" doesnt really guarantee anything
though.

Also clean up wayland only bits as we use them for all windowing systems
now, and the name of the native pointer we want is the same on both
platforms for now.

Remove some unused variables, fix const qualifier and remove printfs.

 - Update LuaJIT according to upstream recommendations (maintainers of
   this project prefer that distributors use the git repository directly,
   instead of archives. Do that, and also update the Lua path for swig.)

 - Update ffmpeg and drop patch which is included in this updated release
   now.

 - Update x264

 - Update nv-codec-headers

 - Update mbedtls

It seems this introduced various regressions on X11 (and, potentially, on other
platforms too, but needs confirmation). Let's preserve the old ways on current
platforms, and only use this flag on the new Wayland platform.

This adds RTX denoiser filter to be used with RTX GPUs.
(from Nvidia Audio Effects SDK)

Remove beta label for YouTube - RTMPS and make it the default. Remove
YouTube - RTMP service and move the legacy RTMP urls to the Server
dropdown list.

Only auto-select WGC for desktop capture if a battery exists and
multiple GPU adapters are present. May false-positive on desktops with
a smart UPS attached, but we don't know of a better test.

Only implemented for D3D11 for now.

Fixes #4207

Closes obsproject/obs-studio#4339

Adds parsing for the "layer-css" query param of URLs dragged into the main window, similarly to the other layer-* parameters already used.

Fixes obsproject/obs-studio#4236

Also add a Frontend API event for when the T-bar's value changes.

If obs was shutting down in very early in initialization like when the
X11 display is missing this context parameter might still be NULL.
Return early to allow shutdown to complete without crashing.

This function wasn't removed in PR 4308.

In CMakeLists.txt, FIND_MODE is not defined here. This was moved from
UI/CMakeLists.txt in commit cb4d2ff7. In
UI/CMakeLists.txt, FIND_MODE is REQUIRED if DISABLE_UI is false or
undefined and ENABLE_UI is true. Since the same booleans are required
for the if-else branch in CMakeLists.txt where we try to find Qt, we can
set find_package to REQUIRED here as well.

UI: Don't attempt to resize parent group when changing cursor

UI: Fix Qt6 build issues

Qt6 enables Qt::AA_UseHighDpiPixmaps by default and will emit a warning
if you try to enable it. To prevent the warning, only set this on Qt5.
