MAME (32-bit)

What's new in this version:

New Features:
- Added the ability to pause while recording to allow seamless on-the-fly removal of video segments. This can only be used when not sharing an encoder with the stream
- Added an option to automatically adjust bitrate when congestion occurs to advanced settings, which is an alternative to dropping frames (available in advanced settings). Note that this currently only works with RTMP, and severe congestion may cause increased delay to viewers
- Added the ability to select multiple sources on the preview by box selection
- Added the ability to create custom browser docks in the View -> Docks menu. This allows you to open extra dockable webpages whenever OBS opens
- Browser sources can now have their volume adjusted via the audio mixer, or have filters applied to them. Additionally, you can now change whether the browser source outputs to speakers or to stream only via the audio monitoring settings in advanced audio properties
- Added a script to pause recording when a specific scene is active
- Added a "Hotkey Focus Behavior" option to advanced settings, which allows you to set whether hotkeys are disabled depending on whether you have the main window in focus or not
- Added an option to general settings to allow users to confirm when clicking the "Stop Recording" button
- Added channels widget for restream.io service integration
- Added the "Area" shader as a downscale shader in video settings
- Added an "Enable Preview" button to the main window when the preview is disabled
- Added (or rather fixed) hardware acceleration support for decoding media files when using the media source where applicable

- Fixed an issue where projectors would have a gray background rather than a black background
- Fixed a bug where secondary Twitch/Mixer browser panels would stop appearing
