v2.3.4

Changes

Bugfixes

• Fixed start_also_resets not sending the split/start hotkey (#351)
• Fixed a crash on Windows ARM64 trying to initialize D3D Desktop Duplication (#357)

Linux source install

(these only affect Linux users building and running from source)

• install.ps1 script won't try to install debian/ubuntu packages on non-debian-based distros (checks if apt-get command is available)
• install.ps1 won't try to install already-installed packages, as to avoid marking them as "manually installed"
• Fixed AutoSplit.py shebang to properly use the environment Python

Full Changelog: v2.3.3...v2.3.4

Which Asset should I download?

• arm64 vs x64: Check your Processor Platform Architecture (note that x86_64 and x64 means the same). If you're still unsure, x64 will work either way. arm64 should be more efficient.
• WineCompat: This is for running the Windows executable under Wine on Linux

Full Changelog: v2.2.2...v2.3.0

v2.2.2

Improvements:

• BitBlt, Force Full Content Rendering and Direct3D Desktop Duplication capture methods can now recover window when 2 windows of the same executable have the same name.
• BitBlt now has a clearer on-screen message for valid windows that have empty buffers (likely not compatible)
• Image comparison timing should be up to 5% tighter by using "precise" Qt Timer Type. Default "coarse" timer type only tried to keep accuracy within 5% of the desired interval. At worst this means a difference of ±2.5ms at 20FPS. See https://doc.qt.io/qt-6/qt.html#TimerType-enum for more details.
• Region Selection's transparent overlay now has a window name (visible when alt-tabbing/hover in taskbar)
• It is now possible to select a window at position (0, 0)

Bugfixes:

• Actually (hopefully) fixed "settings changed" detection for the save prompt on exit. (v2.2.1 made the popup appear when there was no changes)
• Fixed a regression in v2.1.1 to sending LiveSplit commands where AutoSplit was looking at "start_also_resets" setting instead of whether it was being auto-controlled by LiveSplit.
• Fixed Settings window accidentally being resizable
• Region Selection's transparent overlay now has a fixed size in case the user finds some way to move/resize the overlay (backport from the Linux branch)
• Fixed a running loop leak when cancelling the selection or attempting to select a window at position (0, 0)

Internal

• General improvements by reducing now-redundant code and amount of data being passed around.

Full Changelog: v2.2.1...v2.2.2

Which build should I use?

Try the Python 3.12 version. It should be functionally identical, with a marginal performance boost. If you have any issue with it, please report it here or on the Discord server and use the Python 3.11 version in the mean time.

v2.2.1

Improvements:

• When opening the settings window, "Capture settings" is now default and "hotkeys" have been moved to the end

Bugfixes:

• Patched out more SetProcessDpiAwareness in libs to fix OpenCV warnings. May relate to #258
• Fix "ask to save changed settings" detection on application close
• Fix an issue with the "Video Capture Device" Capture Method when capture_device_id is -1. Fixes #252

Documentation

External

obs-virtualcam plugin has been updated to 3.1.0 and now supports OBS 29.1+
Do note, however, that it should no longer be needed thanks to the integrated OBS Virtual Camera support.

v2.0.1

This is a patch release, there are no new features or breaking changes.
Read https://github.com/Toufool/AutoSplit/releases/tag/v2.0.0 for all the changes since 1.6.1

Bugfixes

• Fixed the D3D Desktop Duplication Capture Method not working at all (Fixes #229)
• Fixed an error that could happen with BitBlt Capture Method when closing the target window of a multi-windows application (like Dolphin).
• Fixed pHash comparison method returning a match of 0 upon a perfect match
• Fixed an issue where AutoSplit would automatically restart if the "Loop Last Split Image to First Split Image" was checked, and AutoSplit was manually "Reset" rather than only looping from hitting the last split.
• Fixed some numbers being rounded up in the GUI instead of being truncated. (a 0.996 match was incorrectly displayed as a perfect 1.00 match)
• Better handle some camera errors
  • If a Capture Card isn't currently available available or is not supported by OpenCV, the blank frame given by OpenCV will be used instead of popping up an error. (Closes #58 , relates to opencv/opencv#23539)
  • Hide OBS Virtual Camera to prevent confusion with the plugin and prevent AutoSplit crash when selected.
• Support Dummy Flag for start image (Fixes #222)

Optimizations

• Make the autostart image comparison timer and the live preview refresh timer respect FPS limit setting changes
• Optimize the live preview by re-using the image from comparison instead or requesting another new image

Documentation

• Moved documentation in docs
• Added docs/CONTRIBUTING.md
• Added more ways to help as non-developer in the README
