StreamFX 0.9.3

⚠️ 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.

Notable Changes and Information

OBS should no longer freeze on Startup

This bug was a result of modern machines getting faster and faster to the point that a thread that we just created a few milliseconds ago is already done with work. Everything that interfaces with Qt has now been moved to a more safe location instead, so that this isn't an issue any more.

Source Mirror can now mirror delayed Sources

A workaround was added to Source Mirror which increases its minimum size from 0x0 to 1x1. This is a workaround to allow delayed sources, like Display and Window Capture to work, as those usually start with a 0x0 size and then eventually have a proper size.

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.

Notable Changes and Information

Unicode Support

The majority of features in StreamFX now support Unicode paths, fixing the issues many people had with the Updater and About StreamFX dialog appearing every single time. This might also explain some odd crashes where users had correctly installed the plugin, but the plugin would crash anyway.

Shader filters and Source Mirror sources now support duplication!

Both the Shader filter as well as the Source Mirror source used to ignore the settings given to it when they were created, which is no longer the case. This should fix support for the obs-WebSocket plugin, which relied on this working, as well as Studio Mode in its default configuration.

Dynamic Mask can now use Sources in inactive Scenes!

The filter previously did not inform the referenced Source that it is visible and needs to update as well as render, resulting in a static frame or nothing at all being displayed for certain sources. With this update, Dynamic Mask should be able to use any Source or Scene, no matter in what scene it may be.

Other Changes

• Shader sources/filters/transitions should now only render once per tick, instead of rendering once per view. This may result in a drastic reduction in Shader GPU usage and CPU usage, possibly allowing higher framerates if one of those sources was used.
• A bug in the Qt5 version that OBS Studio ships (until version 26.1) caused the dialog that asks for permission to connect to GitHub to make the parent window unusable if the dialog was opened at a later point in time. This could be achieved by refusing the first dialog, and then checking for updates using the menu, making OBS Studio entirely unusable. Edit: Yes, this fixes the updater dialog blocking the use of OBS Studio.
• The Inno Setup installer now looks for additional installation paths for both the plugin as well as OBS Studio, no longer attempts to run in 64-bit on 32-bit only systems, removes the old plugin before moving on to install the new one, and also installs the MSVC redistributables before moving on to installing the plugin.
• Loading the plugin should now be slightly faster due to further optimizations on often used code.
• Using the "sliding-bars.effect" transition shader example should no longer result in a black screen due to a typo.

Notable Changes and Information

StreamFX v0.9 is safe to use with OBS Studio v26.0!

OBS Studio v26.0 has been extensively tested with StreamFX v0.9, and no notable problems could be found that did not already happen in earlier versions of OBS Studio or the plugin. You can safely upgrade both the plugin and OBS Studio, as long as you also upgrade all other plugins.

Hiding OBS Studio to tray is no longer broken.

OBS Studio incorrectly treats hidden and inactive modal windows as active, causing an invisible window to prevent OBS Studio from minimizing to tray. This has been worked around, and an upstream bug report has been filed.

The Installer is now aware of 64-bit systems.

Due to an oversight in earlier development the installer was built as a 32-bit binary, which meant that it would fail to find OBS Studio installations done with a 64-bit installer. This resulted in some installations ending up in the wrong directory, as the correct path could not be read from the registry. If you previously used the 32-bit installer, please make sure to uninstall first, or you will end up with two installed copies!

Zero-Copy encoding no longer triggers Scaling and Conversion.

Earlier versions of the plugin had a chance to trigger extra CPU and GPU usage while zero-copy encoding was active, drastically reducing the maximum possible performance. This has now been fixed, and the proper fallbacks encoders are being used for settings that can't be performed in zero-copy mode.

FFmpeg Encoder is now able to encode sRGB correctly!

A misunderstanding of what certain values mean in FFmpeg resulted in some encoders incorrectly tagging YUV 4:4:4 (I444 in OBS) as RGB 4:4:4, making video players and editors freak out a little bit. This has now been adjusted, so that sRGB works correctly, allowing crystal clear sRGB footage.

The "hexagonize.effect" Shader now creates actual hexagons!

Thanks to @Toasty27, an oversight when porting the shader from ShaderToy was found that caused hexagons to be created with the wrong size, resulting in malformed hexagons.

Version 0.9 brings several much needed fixes as well as improvements, from user experience changes in NVENC to internal fixes to improve plugin and libOBS stability. Let's go over the major changes:

Integrated update checking!

Tired of having to manually refresh the plugin page in the browser to find new updates? Well look no further than this new addition! The plugin now includes a manual and automated way to check for updates, entirely within OBS! You can even select which update channel you want to be notified for.

FFmpeg Encoders are now available on Linux!

The user friendly FFmpeg Encoder interface is now also available on Linux systems, enabling Linux users to also get the best possible quality out of their system. While zero-copy is not supported due to a libOBS limitation, everything else should work as expected.

Improved user interface for NVIDIA NVENC encoders!

The user interface for NVIDIA NVENC (via FFmpeg) encoders was slightly changed to improve the user experience. Some unsupported values have been permanently removed until a newer NVENC generation adds them to the hardware.

Randomization support in Custom Shaders!

Improve your custom shaders by adding a bit of a random variation to them! Shaders now have access to 16 pseudo-random values which can be used to add some flair to the shader of your choice. Don't stick with boring static shaders, enhance them with a bit of variation!

New custom shader examples!

Thanks to @Oncorporation and @robmoggach, we now have additional custom shader examples, readily available for you to use! @Oncorporation added extra techniques to the "Luma Burn" effect, and @robmoggach ported this ShaderToy to StreamFX. Huge shoutout to them for submitting these additions!

• Fixed that "Adaptive B-Frames" is not actually being applied in the NVENC FFmpeg Encoders.
• Improved the performance of various rendering steps by using a single fullscreen tri instead of a quad (See #199). The effects should be immediately noticable with mip-mapping and some of the Blur effects.
• Added optional performance profiling which by default is not compiled in. Developers can choose to build StreamFX with it if they wish to check for possible optimizations.

• Added an entry into the OBS Studio tools menu which links to important things such as where to get help and where to report bugs.
• Added an "About StreamFX" window to thank all supporters, translators and contributors. This window opens once automatically when a new version of the plugin is installed, and otherwise is accessible via Tools -> StreamFX -> About StreamFX.

0.8.0b1

• Updated translations from Crowdin, huge thanks to everyone submitting translations!
• Fixed FFmpeg Encoders not respecting user selected color formats and instead always using YUV 4:2:0. (#136)
• Fixed FFmpeg ProRes not correctly overriding color formats with the ones supported by the selected profile. (#136, 140)
• Fixed a lot of code issues by actually jumping ship to modern C++.
• Fixed some sources not tagging the settings object with the current version, making migrating settings problematic.
• Removed the lib prefix from the StreamFX.so files on Linux. Make sure you delete the old version of the plugin first if you're using Linux!

0.8.0a4

• Updated support for libOBS v25.0.3 and newer.

• Fixed audio mirroring only working every second configuration update in Source Mirror.

0.8.0a2

• Added FFmpeg Encoders which expose various encoders available in FFmpeg to you with a neat, easy to use UI (if you can read tooltips). You will find them available under either Streaming or Recording, depending on the codec you want to encode. This integration is slightly different from the one in obs-ffmpeg-encoder, so the two plugins will clash and you should remove obs-ffmpeg-encoder ahead of time using its uninstaller entry.
• Improved Custom Shaders further, however these are still very experimental. Expect these to crash, corrupt or otherwise eat your setup in unexpected ways, and also expect these to change wildly.
• Improved Audio Mirroring in Source Mirror by relying on a global thread pool instead of a thread per source, drastically reducing the total CPU load in massive setups.
• Removed scaling from Source Mirror which was mostly broken anyway, so please use any of the available filters instead.
• Fixed a possible crash in multi-core systems caused by event callbacks.
• Fixed various crashes and corruptions caused by Source Mirror, Dynamic Mask and Blur.

0.8.0a1

• Important: The plugin was renamed to StreamFX, users that manually installed this plugin (or manually built it) must ensure that the old obs-stream-effects ...

• Fixed the 'drunk.effect' example shader and added even worse options to it.
• Fixed Shaders rendering larger or smaller than the specified size.
• Fixed Shaders rendering once for each time they are drawn per tick instead of only once per tick.
• Fixed Direct3D11 evicting important textures before encoders had a chance to work with them in high GPU usage situations.
• Fixed "Look Ahead", "Adaptive I-Frames" and "Adaptive B-Frames" not being applied as expected.
• Improved the performance of the Nvidia Face Tracking filter massively by moving almost all of it into worker threads.
• Added a default path to the Shader file selection dialog.
• Added various ShaderToy shaders (shadertoy-#####.effect) and a new semiline.effect which was used for the StreamFX logo.
• Added an entry into the OBS Studio tools menu which links to important things such as where to get help and where to report bugs.

0.8.0b1

• Updated translations from Crowdin, huge thanks to everyone submitting translations!
• Fixed FFmpeg Encoders not respecting user selected color formats and instead always using YUV 4:2:0. (#136)
• Fixed FFmpeg ProRes not correctly overriding color formats with the ones supported by the selected profile. (#136, 140)
• Fixed a lot of code issues by actually jumping ship to modern C++.
• Fixed some sources not tagging the settings object with the current version, making migrating settings problematic.
• Removed the lib prefix from the StreamFX.so files on Linux. Make sure you delete the old version of the plugin first if you're using Linux!

0.8.0a4

• Updated support for libOBS v25.0.3 and newer.
• Added support for Ubuntu 18.04 and 19.10, take a look at the platform parity wiki page to see what is missing.
• Fixed potential memory corruption caused by FFmpeg Encoders.
• Fixed a regression introduced in 0.7.2 which causes 3D Transforms to suddenly invert. (#116)
• Added Custom Shader Filters, Sources and Transitions - and also added extra examples for them.
• Added Nvidia Face Tracking filter which will be available at a later point in time.
• Updated translations from Crowdin, many thanks to all the volunteer translators!

0.8.0a3

• Updated support for libOBS v25.0.1 and newer.
• Fixed 3D Transform causing discoloration in transparent sources. (#104)

0.8.0a2

• Added FFmpeg Encoders which expose various encoders available in FFmpeg to you with a neat, easy to use UI (if you can read tooltips). You will find them available under either Streaming or Recording, depending on the codec you want to encode. This integration is slightly different from the one in obs-ffmpeg-encoder, so the two plugins will clash and you should remove obs-ffmpeg-encoder ahead of time using its uninstaller entry.
• Improved Custom Shaders further, however these are still very experimental. Expect these to crash, corrupt or otherwise eat your setup in unexpected ways, and also expect these to change wildly.
• Improved Audio Mirroring in Source Mirror by relying on a global thread pool instead of a thread per source, drastically reducing the total CPU load in massive setups.
• Removed scaling from Source Mirror which was mostly broken anyway, so please use any of the available filters instead.
• Fixed a possible crash in multi-core systems caused by event callbacks.
• Fixed various crashes and corruptions caused by Source Mirror, Dynamic Mask and Blur.

0.8.0a1

• Important: The plugin was renamed to StreamFX, users that manually installed this plugin (or manually built it) must ensure that t...

StreamFX 0.8.1

⚠️ 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.

---

Please use the most up to date version of StreamFX! You can find it here.

It has been just under two months, and it's time for a patch release! A number of critical bugs have been fixed, which should result in an improved user experience, OBS stability, and perhaps even higher performance.

Source Mirror sources and Shader filters should no longer turn invisible!

Scene collections which heavily relied on these should now no longer have any issues with them, and properly show them. While the underlying cause has not been fully fixed, it should fix the issue for the majority of use cases for now. Known problematic mirror inputs are async sources that get a size at a later point in time, and sources without a size.

Shader filters now capture at the correct resolution!

Get all the quality out of your shader filter, instead of only a fraction of it! Effects made using shaders should now look cleaner than ever before, and performance should return to normal for shaders that were set to >100% size.

The Windows installer has been reworked!

The installer now automatically installs any missing Microsoft Visual C++ Redistributables, and should look much more modern compared to before. Additionally the confusing upgrade step has been simplified significantly, so installing the plugin is now easier than ever before!

Tons of memory leak were fixed!

A lot of undiscovered memory leaks appeared while testing more complicated setups. These have all been fixed now, and you should no longer encounter any memory leaks within StreamFX itself. There is still one known memory leak that is caused by OBS Studio, which will be fixed by a future update to OBS Studio - stay tuned for that!

Do you like StreamFX? Consider supporting the project!

This plugin is only possible through the continuous support through Patreon, Github Sponsors and Twitch subscribers. If StreamFX has helped you achieve your ideal setup, consider supporting the project through one of the platforms. Even a 1$/mo support helps with the development of the project so that I don't have to seek other means of funding.

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.

Please use the most up to date version of StreamFX! You can find it here.

It's finally time for the long awaited full and final release of StreamFX 0.8.0! As the new baseline version for future updates and improvements, 0.8.0 brings with it a lot of fixes, performance improvements, and even some new additions!

Support the StreamFX project!

If you rely on StreamFX for your streaming and recording needs and want StreamFX to continue existing, consider supporting me on Patreon or on Github Sponsors! Even a support as low as one dollar per month means a lot and helps keep the project afloat, and if every single user of the plugin was supporting me with just one dollar per month I could spend a lot more time working on the project than I do now. So what are you waiting for?

Help & Support

Before installing this plugin, please make sure to read the Installation Guide which includes the necessary prerequisites for succesfully getting StreamFX to run. If it still does not work, consider joining the official Discord.

Please make sure to read the Installation Guide!

The installation guide covers many common issues, such as the plugin not appearing. Please make sure to read it in its entirety.

Notable Changes (since 0.7)

Support for 32-bit has been stopped!

With 0.8.0a1 I stopped officially supporting the use of the 32-bit plugin and OBS Studio, and with this release it is now set in stone. If you are still stuck on 32-bit, you will have to stick with older versions of the plugin, but the majority of you should already have a 64-bit capable system and should be using the 64-bit version of OBS Studio.

FFmpeg Encoders are now part of StreamFX

Yes, that's right: my old ffmpeg-encoders plugin is now fully merged into StreamFX. This is to reduce my effective work load in supporting two code bases with the same fixes, instead of just applying them to one. This also has the additional benefit that I can use any of the helper classes of StreamFX in the FFmpeg Encoders to improve their quality and UI/UX.

Custom Shaders are here!

With 0.8.0a3 custom shaders were introduced, and they are now here to stay. This release marks the first stable release of the Shaders, which can be added as a Source, Filter or Transition! They are incredibly powerful, and will recieve many new abilities later on into development. Just take a look at the page on the wiki to see what they can do.

Keep your face in the frame with the NVIDIA Face Tracking filter!

Thanks to NVIDIA you now have a way to bypass all the annoying work of manually cropping your camera to fit in the frame. Just add the filter, and it will take care of tracking the region that should be kept in the frame, so that you can focus on your content! (Requires an NVIDIA RTX GPU to be present and in use by OBS Studio.)

Added a new UI integration for StreamFX!

You can now find a new StreamFX menu in OBS Studio if you've installed it correctly. It contains many useful links, including links to the community and direct links to reporting issues, as well as the new 'About StreamFX' window. The 'About StreamFX' window shows all the people that have contributed towards the development, and contains information about the version of the plugin you are currently using.

Performance Improvements

There has been work to increase the effective performance of StreamFX through the use of more modern coding ways, including some compiler optimizations. These improvements should lead to a 10% reduction in CPU and GPU usage, more if you're using a Laptop or mobile APU.
