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]

30.2 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]
