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- #440 Removed support for Ubuntu 18.04 as it ships seriously outdated versions of libraries we use.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.
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.
The MODULE_EXPORT and EXPORT macros in libOBS do not correctly mark a function or type as visible on GCC, which results in the newly added flag hiding everything from view, instead of just what should be hidden.
The commit 8163e3e917 introduced a complete refactor of the CMake script in order to improve future updates, but accidentally broke building with OBS Studio due to only testing the standalone model. By correctly adjusting the option name again, this should work again with this change.
Fixed: #351
Refactors the entire file to be more readable while also improving the possibility of future improvements. Components are now resolved in one go instead of being all over the place, and shared dependencies are now only resolved once instead of multiple times.
For future compatibility sake, all features now default to enabled and will instead show a warning if they can't be enabled, or if their dependencies can't be found. Pay attention to the build log if you encounter this, as it should hint you towards what is missing. Some features are also now optional, instead of being required.
Furthermore the "Reference" and "Package" mode for building have been removed as supporting them has been a problematic thing from the start. While their structure technically matches the one that is downloaded, effectively they can result in unpredictable issues.
A number of other issues have also been fixed, like Qt being invoked for non-Qt source files.
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.
* #307 Fix MSVC exclusive strcmp crash in FFmpeg Encoders.
* #310 Add shadertoy effect.
* #311 Move template files to custom directory.
* #312 Hide encoders that the current system does not support.
* #313 Enable FFmpeg Encoders on Linux.
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.
Using '-Wpedantic' on any GCC warnings enables a lot of annoying warnings that don't actually warn about anything. Some of the warnings seem to exist purely for maintaining a certain code style, and have no actual effect on the program itself. Since there is no way to selectively disable warnings like on MSVC, removing it is the easiest choice.
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.
Adds a BeforeInstall step to the InnoSetup installer which uses the msvc-redist-helper tool to automatically check for the necessary DLLs and install the required redistributable if some are found to be missing.
Additionally slightly modernized the installer with a design that isn't from the 90s, and paves the way for preventing updating StreamFX while OBS Studio is still running.
