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.
* Fixed a bug preventing versions from being parsed correctly in CMake.
* Fixed a bug introduced between 0.9.3 and 0.10.0b1 which broke transparency support for Color Grading.
* Added support for direct rendering to some sources/filters/transitions.
* Added .pkg based Installer for MacOS, thanks to @cpyarger.
* Updated translations from Crowdin.
Enables users of the Mac Operating System to use an automated installer instead of the manual installation method which is prone to user errors. This is done via the use of "Packages", which generates a .pkg file according to the requirements we present it.
When the CMake script was rewritten, not much attention was put into the versioning code, resulting in odd behavior which was never found or fixed. For example, the automatic splitting of the suffix from the number never worked, and the build number was being stored in the wrong variable.
* 3D Transform should now appear again.
* Automatic disabling of unsupported features should now work in CMake.
* Fixed a compilation error on some versions of GCC.
- #437 Use 'git describe --tags' for versioning.
- #439 Add support for overriding the automatically detected version.
- #454 Fixed new versioning code breaking when the tag is on the current commit.
- #427, #428 Fix Qt interaction before OBS Studio is actually ready.
- #452 Fixed building without updater but with UI.
- #447 Redesigned Color Grading to support two rendering modes:
- Direct Rendering applies the entire color grading function to every single pixel, and is thus more accurate, but much slower.
- #-Bit LUT Rendering first applies the color grading function to a LUT that varies in accuracy, and then uses that LUT to render the actual output instead, which is much faster but less accurate.
- #447 Optimized Direct Rendering in Color Grading to be up to 25% faster, while using 50% less VRAM.
- #440 Removed support for Ubuntu 18.04 as it ships seriously outdated versions of libraries we use.
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.
