  OBS Studio 29.1测试版新功能

  

  •   新功能

      为Windows添加了DLL阻止功能。这允许OBS阻止有问题的DLL连接到OBS并导致冻结或崩溃,例如第三方覆盖挂钩和过时的视频捕获设备。[第1次]

      阻止了流行的VTubing软件虚拟摄像机的旧版本,这些虚拟摄像机在访问视频捕获设备财产时会导致冻结。如果您受到影响,请更新到您的VTubing软件的最新版本。

      在macOS上添加了更新频道,并更新了Sparkle,以实现更小更快的更新[derrod]

      添加了选择用于流式传输和录制的音频编码器的设置[tytan652]

      添加了一个选项,可以将Stingers中使用的媒体源预加载到内存中,以避免在转换过程中跳过帧[Jim]

      添加了使用Ctrl-和+以及右键单击菜单[WizardCM]缩放浏览器停靠的功能

      添加了一个以分段MP4和MOV格式录制的设置[derrod]

      这些提供了比MKV更大的兼容性,同时提供了类似的抵御因崩溃、空间不足等原因造成的数据丢失的能力。

      在MP4/MOV文件可能无法正确读取的情况下(例如,在较旧的编辑软件中),可以将分段的MP4和MOV文件重新复用为常规MP4/MOV

      默认录制格式已暂时更改为碎片MP4/MOV,如果遇到任何问题,请在Discord或论坛上提交您的反馈!

      扩展了对VLC源字幕音轨的支持(最多1000个)[jjm2473]

      在切换到之前,设置中的“热键”选项卡将不再加载,这导致“设置”窗口对于大型场景集合的打开速度要快得多[derrod]

      切换各种内部数据结构以使用哈希表进行查找,从而显著提高了性能,并通过大型场景集合节省了加载/时间[derrod]

      导出的场景集合JSON现在可以很好地打印和排序,从而可以更容易地通过git或其他版本控制机制进行跟踪[derrod]

      在帮助菜单中添加了一个“新增功能”条目,以手动打开更新后的更改日志对话框[derrod]

      点击财产中的“默认值”按钮,将在重置[derrod]之前要求确认
