Both Rec. 601 and sRGB looked extremely wrong before, resulting in weird or warped colors. Since it is very difficult to find up to date and accurate information on standards, we should simply go for what has the most widespread support.
There is hardly any reason for us to recalculate everything all the time. LUTs can cache the work once, and then re-use it every time necessary, drastically reducing the impact of Color Grading by almost 60% (on some GPUs even more). Additionally this fixes the negative gamma issue, which plagued the filter for a while.
In the future, once PR 4199 (https://github.com/obsproject/obs-studio/pull/4199) has been merged, we can cut away one intermediate rendering step currently required to make the effect work. Hopefully this will be with the 27.x release of OBS Studio.
For simple image and video editing, LUTs (Look-Up Tables) are vastly superior to running the entire editing operation on each pixel - especially if all the processing can be done inside a single shader.
Due to the post-processing requirements for our LUTs, we are limited to 8 bits per channel - though clever use of the unused Alpha channel may result in additional space. For our purposes however, this is definitely enough.
A complete redesign of the component and dependency system is necessary in order to support additional platforms, such as MacOS and other Linux platforms. Additionally it results in a much cleaner code base, which is less confusing overall.
Eventually it might be necessary to push components of StreamFX into their own CMake projects, as it is getting kind of complex now. Especially with the push for a proper plugin manager, things get dicey for big plugins like StreamFX.
Ignoring the data parameter during initialization results in duplication and some third party plugins not working as expected, so it's better to not ignore it.
Fixes#315
Adds support for the AMD Advanced Media Framework H.264 and H.265 encoders via FFmpeg. The majority of settings are supported, and the UI/UX experience mimics that of the NVENC implementation. Various settings are left out due to their complexity and should be controlled via the custom parameters field.
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.

This fixes a bug with older Qt versions which would not remove the modal window from the parent in the setModal() call, resulting in an unusable parent window.
Fixes#368
Improves the previous logic and makes it compatible with the new additions in 26.x, such as sRGB. This was previously broken as the focus was on existing features which could be tested without requiring a compiler to be installed.
Incorrect understanding of how sRGB works with RGB and YCC/YUV formats also caused sRGB to be treated as RGB when I444 was selected. This should also now be fixed, hopefully permanently.
Fixes#331
In order to work around a bug in the OBS Studio UI code, we have to swap our modal status right before showing and right after hiding, so that the OBS Studio tray menu continuous working correctly. This is a bit of a weird solution, but it does work as expected.

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.
Removes the NVENC entry on systems without an NVIDIA GPU by checking if the library for it can be loaded. If it can't be loaded, it's likely that the user does not have a system with NVENC capabilities - and guaranteed that they can't use the encoder as FFmpeg relies on these libraries.
Adds a utility class and functions to load libraries and symbols from libraries somewhat safely. Libraries are immediately unloaded when the last reference to them is lost, so the shared_ptr should be stored if the library is actually needed.
