While the previous approach of a static thread pool worked, it was sub-optimal in its resource usage. Many of the threads would never see a single task, and simply permanently sleep. This seems like a good idea, except that sleeping threads still end up in the scheduler, and thus waste a tiny amount of resources.
It is better to instead dynamically spawn threads when needed and only keeping the bare minimum around all the time. These dynamically spawned threads are also explicitly set to background priority which further reduces scheduling overhead. Finally optimizing the memory layout to prevent unwanted false sharing should also keep sporadic wake ups at a minimum.
This new model should be able to handle many more tasks than ever before, but is still not as optimal as it could be.
In some rare cases, a bug is observed where some sources end up missing despite being visible in the OBS Studio UI. This is most likely related to us actually missing the events due to plugin load order. We can fix this by explicitly enumerating sources in the constructor.
Additionally in order to reduce the human error factor, we should avoid explicit initialize() and finalize() calls for our singleton. Instead the get() function should do all of the heavy lifting, including thread safety, so that the human writing the code will have next to no chances to break it.
Originally intended to be an experiment with no future, it turned out to be very popular with streamers that move a lot. In the end it was popular enough that NVIDIA added their own variant to their Broadcast software, which works decently enough. Unfortunately my wrapper code around the library was written very poorly, so it didn't take long for it to break out of nowhere.
The previous name was too strict on what could be put into the effect, and would result in additional clutter in the Filter menu when we eventually decide to support other Upscaling methods than Super-Resolution networks.
Using the obs_module_file and obs_module_config_path macros works okay, but it comes with a slight overhead as well as additional requirements when passing it to C++ functions that expect certain rules to be fulfilled. By instead wrapping the actual functionality into our own functions and using those we can avoid most of the issues that come with the old approach.

Implements a manual and automatic update checker with support for both release and testing update channels, allowing users to stay as up to date as possible. It is fully compliant with privacy regulations around the world, as it stays completely silent and inactive until the user gives the Ok to connect to GitHub for the latest releases.
Changes applied:
* Moved utility files to /util/.
* Removed unused #includes.
* Removed unused ::ffmpeg::tools function.
* Removed unused variables.
* Fixed missing parentheses in the version macro.
* Fixed missing override on virtual function overrides and removed unnecessary virtual keyword from them.
* Disabled additional warning for ATL headers on MSVC only.
* Replaced direct printf parameters with their macro equivalent.
* Replaced C-style casts with C++-style casts.
* Applied clang-format again after an earlier change to the CMake file broke the integration for it.
Implements support for various new UI features that weren't possible up until now, such as an 'About StreamFX' window with a thank you to everyone that supported the project up until now.
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.
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
This thread pool can take large or small tasks and as such alleviates the burden of having a thread per source. Particularly for large setups, this drastically reduces the number of threads running in the background waiting for work.
This is a massive improvement to stability and safety when using the plugin, as all exceptions should now no longer be leaked into C controlled code, which can't actually handle exceptions at all.
Warnings fixed:
* Potentially throwing exception during library load.
* Possibly throwing function passed to C.
* Statement does nothing.
* Variable is initialized but not referenced.
* Variable overloads variable in parent scope.
The number of files in the source directory was a little bit much and just made file naming more complex than it had to be. Therefore all files were moved into subdirectories where it matters.
Filters now reside in source/filters/, Sources in source/sources/, OBS Wrappers in obs/, OBS GS Wrappers in obs/gs/, Transitions will reside in source/transitions, Graphics Helpers will be in gfx/.
Allows for enumerating any kind of source, as long as it has a name and is not private. As obs_enum_scenes is a 23.x and above function, this class should be used instead to remain backwards compatible.
