⚠️ Binaries removed due to GPL license violation! ⚠️

We had to remove binaries and source code due to a contributor submitting code that was not licensed under the GPLv2 "or later" license or any compatible license. While we were able to adjust the source code contained in the repository to exclude these license violations, we can't guarantee that binaries will be available again.

Enjoying the benefits of StreamFX? Then support it on Github Sponsors or Patreon!

The StreamFX project is only possible through your support, either as a translator or as a Supporter on either Patreon or Github. Your support helps keep StreamFX free from Ads, even if it's just translating a few lines per month, or 1$ per month. If continuous support isn't your thing, maybe a one-time donation via PayPal is?

Changes to Platform Support

MacOS 10.15 and newer is now officially supported!

Thanks to Elgato sponsoring a MacOS device and cpyarger, the StreamFX project now supports MacOS for the majority of features! Just as with Windows, both the automated and manual Installation methods are available, and the Installation Guide already has been updated with steps for MacOS.

Ubuntu 18.04 is no longer supported!

As Ubuntu 20.04 has been released, the support for 18.04 (and 19.10 by extension) has been permanently dropped. We will continue dropping older platforms as they get improved in order to stay performant on modern systems - there is no point chasing the past, as it will only get further away with time.

Changes to Sources/Filters/Transitions

Source Mirror can now mirror delayed sources!

While the fix for this is more of a work-around, it does what it promises. Source Mirror now has a minimum size of 1x1 which it will never go below, thus allowing it to mirror delayed sources like Display Capture, Video Capture Source, etc.

Some Sources/Filters/Transitions now support Direct Rendering.

Direct Rendering in OBS skips a small buffering step in OBS Studio, resulting in slightly better performance in VRAM or Memory-Throughput constrained situations. The gains here should be nothing on good hardware, but somewhat noticable in restricted situations.

Color Grading is now much faster!

A lot of work has gone into making Color Grading faster in order to allow more users to use the filter while live streaming or recording. It now has two ways to render the effect, with the first one being "Direct Rendering", and the latter being "#-Bit Look-Up Table" - the new default. The former method is now up to 25% faster than before, while the latter uses up to 75% less GPU time and up to 25% less GPU memory.

You can personally choose to further reduce the GPU impact while sacrificing accuracy by opting for a smaller Look-Up Table. The default accuracy is 8 bits per channel, but you can freely select 6, 4, or even 2 bits per channel. Optionally if you do not like faster rendering, you can also opt for the old "Direct Rendering" method again.

Color Grading's Lift and Gain have been improved.

The Lift functionality of Color Grading was broken since it was added and has finally been fixed. You can now correctly lift the black level or reduce it, as you would have expected. Additionally the ranges for the Lift and Gain options have been adjusted to more sensible values.

Changes to Encoders

The FFmpeg AMD Encoder integration is ready for use!

After several months of testing, the AMD Encoder is now finally ready to be used by everyone! This brings the much coveted zero-copy encoding over to the AMD side. Whether it's high framerate gaming, or GPU heavy applications, AMD users can now enjoy similar performance improvements that NVIDIA users have been enjoying.

sRGB and Rec. 601 color tagging has been fixed.

Due to both standards having multiple definitions, none of which actually perfectly fit anything, footage recorded using these profiles may be played back or converted incorrectly by other tools. This should now no longer be the case, as sRGB has been adjusted to the fixed 2.2 Gamma (due to a lack of an actual sRGB curve in FFmpeg 4.2.x), and Rec. 601 now mimics what PAL regions would experience. This should make recordings of sRGB content look and feel correct, even if we aren't perfect yet.

Other Changes

The tooltips have been replaced with a button to open the Wiki!

In order to improve the user experience, the manual for each feature is now directly accessible via a button in the properties for each feature. This replaces the often outdated tooltips which were difficult to see and had scattered information or wouldn't even render correctly due to their size. Hopefully this should also reduce the technical knowledge required by translators, as it was getting a bit ridiculous how much a translator had to know.

Minor Changes

• Translations: Updated translations from Crowdin. Thanks to all translators!
• Fixed a bug causing OBS Studio to freeze on Startup when a new version was found.
• Added a pixelation shader filter example submitted by kilinbox, which allows selective pixelation based on user parameters.

Please make sure to read the Installation Guide!

The installation guide covers the required hardware and software to run the plugin, and how to install it through the various options. Please make sure that you have read it in it's entirety before asking for help, as most issues can simply be solved by reading it and actually following all the steps, including installing the necessary prerequisites.
