OBS Studio 30.2 new features:
- Added support for Multitrack Video streaming [palana]
- On Twitch, this is known as Enhanced Broadcasting. Currently, this requires Windows and an NVIDIA GPU. Support for other platforms and GPU vendors is planned. For more information, see: https://help.twitch.tv/s/article/multiple-encodes
- When this feature is enabled, the following data about your system will be sent to the streaming service when starting a stream:
- OBS config info (canvas width and height, frame rate, encoder width and height, VOD Audio Track setting, OBS version)
- CPU info (name, speed, core counts)
- GPU info (model, memory, driver version, device ID, vendor ID)
- Memory info (free, total)
- OS info (name, version, arch, emulation)
- Windows info (gaming feature status: Game Bar, Game DVR, Game Mode, Hardware-accelerated GPU Scheduling)
- Multitrack Video settings (maximum streaming bandwidth, maximum video tracks)
- Added support for Enhanced RTMP/FLV multi-track audio and video [palana/kc5nra]
- Replaces the old metadata-based "VOD Track"
- Added "Hybrid MP4" output format (BETA) [derrod]
- Combines fault-tolerance of fragmented MP4 with wide compatibility and faster access times of regular MP4. For more information, see: https://obsproject.com/kb/hybrid-mp4
- Supports inserting chapter markers into the file via a hotkey or API. These markers are supported by most video players and editing software, such as DaVinci Resolve
- Added Linux support to the native NVENC encoder [derrod]
- NVENC AV1 is now supported on Linux
- Added Linux shared texture support to the NVENC encoder [derrod]
- Added Linux shared texture support to the QuickSync encoder [kkartaltepe]
- Added Linux shared texture support to the VA-API encoder [nowrep]
- Added HEVC support to WebRTC output [murillo128]
- Added Composable Themes system to simplify theme creation, maintenance, and enable future customisation options [derrod/Warchamp7]
- Themes now consist of a base theme and variants that can be switched between in the new "Appearance" settings tab
- Old themes will no longer work and will need to be updated to the new system. See the wiki page for details.
Changes
- Various UI and Theme tweaks [Warchamp7]
- Audio of multiple instances of a source in a scene/group is now deduplicated [derrod]
- Deduplication is recursive, but does not apply on groups or nested scenes that are currently playing show/hide transitions, this may be fixed in the future
- Scene Collection specific plugin data is now retained for plugins that are not currently loaded [derrod]
- Closed-captions are now supported for HEVC and AV1 [jhnbwrs]
- Qt Fusion style is now always enforced on Linux [tytan652]
- Combined PipeWire window/display capture into unified "Screen Capture" source to align with other platforms [tytan652]
- Renamed "Screen Capture (XSHM)" as "Display Capture (XSHM)" for consistency with other capture sources [tytan652]
- Set default recording format on macOS to fragmented MOV [gxalpha]
- Improved freetype2 text source performance [kkartaltepe]
- File open dialogs now start in the directory of the currently selected file, rather than the default [Warchamp7]
- Moved warnings in advanced output to bottom of settings window for better visibility [GPattenden]
- Various performance improvements for texture encoding [kkartaltepe]
- Prioritize NVDEC decoder on NVIDIA systems [moocowsheep]
- Support NVDEC decoder for encoded DirectShow sources [moocowsheep]
- Replaced non-texture NVENC FFmpeg fallback with native implementation [derrod]
- Log now includes all available encoders [Penwy]
- Reset duration of scene item show/hide transitions when removing the transitions [Warchamp7]
- Adjusted appearance of volume meters [Warchamp7]
- Adjusted appearance of multiview borders and labels [Warchamp7]
- Added support for audio-only and video-only WHIP outputs [tt2468]
Bug Fixes
- Fixed packet priority not being set for some AV1 encoders, resulting in outputs never recovering from dropping frames [derrod]
- Fixed various issues with audio channel layouts in (remuxed) recordings [pkv/derrod]
- Fixed various issues with the native FLV muxer [palana]
- Fixed various issues with the RTMP protocol implementation [palana]
- Fixed minor errors in HEVC and AVC decoder configuration records [derrod]
- Fixed change discard confirmation dialog popping up twice when closing source properties [tytan652]
- Fixed QSV AV1 on multi-GPU systems [thyintel/derrod]
- Fixed FFmpeg output erroneously checking disk space when not writing to a file [RytoEX]
- Fixed auto-config wizard not working without a stream key [mar10iana]
- Fixed text alignment with extents [exeldro]
- Fixed encoder properties having nested scroll areas in output settings [derrod]
- Fixed crash if input video resolution changes when using hardware-accelerated decoding [tt2468]
- Fixed button text being cut off in controls dock [powersagitar]
- Fixed undo action for filters showing UUID instead of name [derrod]
