MAME (32-bit)

What's new in this version:

New Features:
- Added the ability to capture Vulkan-based games with game capture. Big thanks to Ubisoft Montreal for submitting this feature
- Added a new capture method to window capture which allows capturing browsers, browser-based windows, and Microsoft Store (UWP) programs: By default, it will use "Automatic", which will use the normal method on most windows, and the new method on browsers, browser-based windows, and Microsoft Store (UWP) programs,
 The downside of the new method is that it can cause a bit of cursor lag, as well as a highlighted border around the captured window. The border itself does not get captured, however;
 You can choose which capture method to use in window capture properties
- Added advanced scene collection importing (on the menu bar, Scene Collection -> Import) which allows you to import from other common streaming programs
- Added Media source hotkeys to allow control of playback (stop/pause/play/restart):For now, these are just hotkeys. User interface for this is also planned for future updates
- Added the ability to drag and drop URLs to create browser sources (after displaying a confirmation prompt to ensure it was by intention): Developers can add an embed to their web pages that let them pre-specify parameters that automatically get set in the source when it's dragged into OBS. See this link for more details: https://obsproject.com/tools/browser-drag-and-drop
- Added T-bar to studio mode: Note that this will not work while using a Stinger transition or the "Cut" transition
- Added support for the SRT protocol (https://en.wikipedia.org/wiki/Secure_Reliable_Transport): This is available by choosing "Custom" under Stream settings > Service, then entering your srt:// path into the Server box.
- Added a button grid mode to the scenes list, which can be toggled via right-clicking on the scenes list
- Added ability to lock volume values of audio sources via their right-click context menu in the mixer
- Added source icons to the source list that give a more visible indication of their function (can be disabled in the View menu)
- Added support for cube LUT files in the LUT filter
- Added an option to show all audio sources to advanced audio settings
- Added an option to use percent rather than dB in advanced audio properties via right-clicking items in the window
- Added a button to save replay buffer next to the replay buffer button (similar to the pause button on the recording button)
- Added support for certain devices that can automatically rotate their camera output such as the Logitech StreamCam
- Added the ability to change the projector type to the projector's right-click context menu
- Added the ability to copy/paste multiple selected sources
- Added an option to enable/disable BTTV and/or FFZ chat extensions when connecting your Twitch account in the stream section of settings
- Added a system tray icon to show when the recording is paused
- Added a "Custom Quantization Matrix" option to QSV encoder (available on Ice Lake or newer)
- Added an option to toggle looping to the scroll filter
- Added a "Fade to Black" option for quick transitions in studio mod
- Added string specifiers to the Filename Formatting option in advanced settings which allows you to specify certain settings such as resolution and FPS to recording filenames
- Added a hotkey to reset the stats window/panel
- Added help icons when an property has a tooltip associated with it
- Added monitor names in monitor selection context menus
- Video settings now shows aspect ratio of canvas and output resolutions

Changes:
- Increased default size of color source to the size of the canvas
- Increased default size of text in text sources
- Increased the number of files you can open with the image slideshow at once
- Added various minor performance improvements
- The mask filter will now reload the mask automatically if the mask file has been modified
- The browser source now uses a monospace font for the custom CSS property
- Redesigned Decklink output UI by combining the start and stop buttons and highlighting them when the output is active
- Removed the older deprecated NVENC encoder in advanced output mode to prevent confusion. You will now only see "NVENC (new)" (which we will eventually rename back to just "NVENC"). Rescaling is now supported on it (automatically falls back to the older implementation internally)

- Fixed a bug when using multiple game captures where the wrong game would sometimes be captured
- Fixed a crash when entering large resolutions in video settings

- Fixed a crash on shutdown that could occur after using the auto configuration wizard
- Fixed a crash with the VLC and slideshow sources when adding directories containing files with many unicode characters
