As OBS Studio locks some mutexes in a different order depending on what actions are being done, using modified_properties for GPU work causes things to freeze in place. Instead have users manually click the refresh button when they changed files in order to prevent this freeze from happening.
Fixes: #118
* Updated libOBS to 25.0.3.
* Improved support for Ubuntu 16.04 and 18.04, for both GCC 8 and GCC 9.
* Fixed#116: Regression from 0.7.1 to 0.8.0.
* Fixed transitions not showing up.
* Added Shader Transitions, Shader Sources and Shader Filters.
* Added new example files for the new Shaders integration.
* Added Nvidia Face Tracking filter (requires compatible Nvidia RTX GPU and Nvidia AR SDK Runtime).
With this, GCC 8 and above should now be able to compile the project both in obs-studio and as a standalone install. Some features are currently still not fully supported and require extra work, but the majority of things are supported and work out of the box. Exact feature parity can be looked up here on the wiki: https://github.com/Xaymar/obs-StreamFX/wiki/Platform-Feature-Parity

This header includes all common data between headers used in the plugin. This should improve cross-platform compiling support whenever possible, as all platform-dependent common includes and defines can be done here.
Ever wished you had a professional camera operator to highlight and follow the action, ensuring the audience never misses a beat? Thanks to NVIDIA, you can now do this at home for free! The new NVIDIA AR SDK unlocks augmented reality features, including motion tracking for faces.
This allows me to provide you with an automated zoom and cropping solution for your video camera to transform your streams into a slick, polished broadcast, where you’ll always be the star of the show. Don’t forget - everything is customizable so the possibilities are endless. You can even recreate that Futurama squinting meme if you wanted to (with some scripting)!
The filter requires compatible Nvidia RTX hardware and the Nvidia AR SDK Runtime to be installed ahead of time. This filter is considered "stable" and shouldn't change much from version to version.
Due to the 'nvcuda' library being part of the driver, it falls in a clause of the GPL which allows us to load and interface with system drivers. Since we can't rely on Nvidias headers here (incompatible license), most of this was pulled from FFmpeg and other things were found out via testing.
CRT Curvature: Emulate an old CRT TVs curvature ...
CRT Scanlines: ... and emulate an old CRT TVs scanlines, rollbar and bleeding!
Hexagonize: Turn things into hexagons. You know, like the thing you see in my streams.
'Time.x' gets inaccurate if OBS Studio is running for more than two hours, therefore we have to do something to fix it. By allowing the shader code to control when things loop using 'Time.y' (0..1) and 'Time.z' (the number of times 'Time.y' wrapped back to 0), a much more stable animation can be achieved.
Color Shift: Uses HSL and some math to smoothly shift Hue Saturation and Lightness between A and B.
Luma Burn: "Burns" away the Luminosity of A to reveal the B side.
Pixelator: Classic/Retro pixelation effect often seen in older games to transition between settings.
These allow you to apply any kind of filtering to a any source, using just standard HLSL. Just like transitions, one extra parameter is set called 'InputA'.
Fixes#95
With this, the first proper shader effect is now possible. By using the four new automated shader parameters 'InputA', 'InputB', 'TransitionTime' and 'TransitionSize' you can write your own transition in HLSL.
Fixes#96
Due to render logic required for transitions, some of the render logic is split into an additional function called 'prepare_render'. Additionally the storage for some temporary objects has been removed as it these objects usually do not outlive their rendering time anyway.

This fixes#116 which was caused by a refactor in commit efb6b0b9be. This bug was left undiscovered until users started upgrading from the last stable version to the current pre-release.
These warnings usually come from the standard code in MSVC or system headers, over which we have absolutely no control. Keeping them enabled does not improve our code at all.
* Updated libOBS to v25.0.1
* Fixed a freeze exclusive to v25.x with Source Mirror.
* Fixed audio mirroring only working on every 2nd configuration update with Source Mirror.
* Fixed audio being mirrored out of order on highly parallel systems (>4 Threads).
* Fixed discoloration of sources in 3D Transform.
* Fixed ffmpeg encoder not falling back to software if scaling is detected.
For an unknown reason, OBS Studio v25.x now causes a freeze to happen at this location. This should hopefully work around that issue by ensuring that we are in a location that does not cause an unusual lock order.
