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, which GPU OBS is using, 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
