While the previous method worked, it matches no other implementation including a reference implementation. The new implementation almost perfectly matches the reference implementation and uses oversampling to achieve the goal. This has the downside of limiting the blur size to just 64, but it is necessary in order to achieve correct results.
Fixes#573
The CUDA library is always available as a singleton, so it does not make sense for it to be passed in. Instead we can simply grab it from the singleton and use it as it is, which makes the code easier to maintain and automates certain code.
This reduces the total amount of links Supporters can submit to just one instead of two. Additionally by removing the buttons and making the entry itself clickable, the UI can show more entries at once and allow users to easily make the connection between the entry and the link it opens when clicked.
The 'obs-ffmpeg-mux.c' file specifies different color parameters than StreamFX does. This causes re-muxing to go haywire, and editors that trust these tags suddenly spew out bad colors for BT.601 and sRGB.
Reverts #478
Qt defaults to give every QAction a TextHeuristicRole, which means that certain key words will cause Qt to change how the QAction behaves. We do not want this, so we explicitly assign it to have NoRole instead.
Fixes#323
Instead of adding ourselves as the last entry which seems to confuse the MacOS Qt implementation, we instead insert ourselves before the Help menu. This should hopefully prevent the StreamFX menu from overriding the OBS About entry.
Fixes#323
Grouping properties by what they do improves the user experience as the user does not have to guess at what belongs to which part of the effect. Additionally toggleable groups automatically disable all child elements, so the user is not confused by them still being active.
While the long descriptions were useful, keeping the updated and translated is pretty much impossible. Technology moves fast and not everyone that translates the project knows a lot about technology.
Therefore the long descriptions have now been replaced with a button that opens the wiki page for the feature instead. This should drastically reduce the number of help cases, and improve the translation coverage at the same time.
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.
