OBS Studio 30.2.0 正式发布 增加了对多轨视频流的支持

30.2 新功能

• 增加了对多轨视频流的支持 [palana]
  • 在 Twitch 上，这被称为增强广播。有关更多信息，请参阅：https://help.twitch.tv/s/article/multiple-encodes
  • 支持的音频通道配置为立体声或单声道。
  • 此功能目前仅适用于 Windows，需要 NVIDIA GTX 900、GTX 10 或 RTX 20 系列 GPU 或更新版本或 AMD RX 6000 系列 GPU 或更新版本。计划支持其他操作系统和 GPU 供应商。
  • 启用此功能后，在开始流式传输时，有关您的系统的以下数据将被发送到流式传输服务：
    • OBS 版本和音频/视频设置（分辨率、帧速率、音频通道/音轨）
    • CPU 信息（名称、速度、核心数）
    • GPU 信息（型号、内存、驱动程序版本、设备 ID、供应商 ID）
    • 内存信息（可用、总计）
    • 操作系统信息（名称、版本、架构、仿真）
      • Windows 信息（游戏功能状态：游戏栏、游戏 DVR、游戏模式、硬件加速 GPU 调度）
    • 多轨视频设置（最大流媒体带宽、最大视频轨道数）
• 增加了对增强型 RTMP/FLV 多轨音频和视频的支持 [palana/kc5nra]
  • 取代旧有的基于元数据的“VOD 轨道”
• 添加“混合 MP4”输出格式（BETA）[derrod]
  • 结合碎片化 MP4 的容错性以及常规 MP4 的广泛兼容性和更快的访问时间。有关更多信息，请参阅：https://obsproject.com/kb/hybrid-mp4
  • 支持通过热键或 API 将章节标记插入文件。大多数视频播放器和编辑软件（例如 DaVinci Resolve）都支持这些标记
• 为原生 NVENC 编码器添加了 Linux 支持 [derrod]

30.2 New Features

• Added support for Multitrack Video streaming [palana]
  • On Twitch, this is known as Enhanced Broadcasting. For more information, see: https://help.twitch.tv/s/article/multiple-encodes
  • The supported audio channel configurations are stereo or mono.
  • This feature is currently only available on Windows and requires an NVIDIA GTX 900, GTX 10, or RTX 20 series GPU or newer or an AMD RX 6000 series GPU or newer. Support for other operating systems and GPU vendors is planned.
  • When this feature is enabled, the following data about your system will be sent to the streaming service when starting a stream:
    • OBS version and audio/video settings (Resolution, framerate, audio channels/tracks)
    • 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]

  • 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: https://github.com/obsproject/obs-studio/wiki/OBS-Studio-Theme-System
  • The legacy System theme is no longer available. If it was used for accessibility reasons with high contrast, enable high contrast in your operating system settings to re-enable the OBS System Theme. OBS can only detect high contrast on Windows and macOS at this time.
