Might fix the problem where people uninstall StreamFX while they still have OBS Studio open with StreamFX loaded. InnoSetup appears to ignore this in /VERYSILENT, so this is an additional guard against that.
This loader model should have wider compatibility, as it relies on defined C++ behavior instead of undefined preprocessor behavior. We may even be able to implement a simple dependency system that automatically sorts components into the correct order.
Fixes several files incorrectly stated a different license from the actual project, as well as the copyright headers included in all files. This change has no effect on the licensing terms, it should clear up a bit of confusion by contributors. Plus the files get a bit smaller, and we have less duplicated information across the entire project.
Overall the project is GPLv2 if not built with Qt, and GPLv3 if it is built with Qt. There are no parts licensed under a different license, all have been adapted from other compatible licenses into GPLv2 or GPLv3.
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.
