直播事件常见问题解答(预览版)Live event FAQ (preview)

什么是编码器?What is an encoder?

简单来说,编码器可压缩来自各种输入的音频和视频,并将相应输出发送到流式传输服务(如 Microsoft Stream)。Simply put, an encoder compresses audio and video from various inputs and sends that output to a streaming service, such as Microsoft Stream. 通常情况下,可以使用硬件、软件和移动应用。Typically, there are hardware, software and mobile apps that you can use. 详细了解 Microsoft Stream 测试过的编码器Learn more about the encoders that have been tested with Microsoft Stream.

为什么看不到“创建直播事件”选项?Why can't I see the "create a live event" option?

拥有允许的许可证的用户(概述中已列出)和 Microsoft Stream 管理员允许的用户可以创建直播事件。Users with the allowable licenses (listed in the overview), and who are enabled by the Microsoft Stream administrator can create live events. 请检查你是否拥有有效的许可证,或与 Microsoft Stream 管理员联系,获取此功能的访问权限。Please check that you have a valid license, or contact your Microsoft Stream administrator to get access to this feature.

谁可以观看直播事件?Who can watch a live event?

直播事件观看者权限的工作原理和 Microsoft Stream 中所有其他视频相同Live events viewership permissions work just like all other videos in Microsoft Stream. 观看者权限可限制为个人或群组,也可面向整个组织。Viewership access can be limited to individuals or groups, or available to the entire organization.

组织外的人员可以观看我的直播事件吗?Can people outside of my org watch my live event?

目前,只有组织内部的观看者能够观看通过 Microsoft Stream 流式传输的事件。Currently, events streamed through Microsoft Stream are only available to internally to viewers within your organization.

可以看到哪些类型的分析?What kind of analytics can I see?

事件制作者可以查看事件直播时观看的总人数。Event producers can see the total number of watchers when the event is live. 事件结束后,制作者可以查看视频生存期内遵循观看计数算法的总观看次数。Once the event is completed, the producer can see the total number of views across the lifetime of the video subject to the view count algorithm.

支持哪些引入协议?What ingest protocols do you support?

Microsoft Stream 支持来自大多数编码器的 RTMP 和 RTMPS 引入。Microsoft Stream supports RTMP and RTMPS ingest from most encoders. RTMP 和 RTMPS 协议的编码器实现可能有所不同,因此建议将测试过的编码器已知的良好配置配合使用。Encoder implementation of RTMP and RTMPS protocol can vary, so it is recommended to use a tested encoder with a good known configuration.

什么是直播就绪状态?What is the pre-live state?

直播就绪状态可帮助制作者设置直播事件。The pre-live state helps producers to set up their live event. 处于此状态时,观众无法看到直播流。在你选择启动直播事件之前,他们只能看到一块盖板。When in this state, audience members will not see your live stream, but will be shown a slate until you choose to start the live event. 在此状态下,可选择断开与设置的连接,以便稍后返回。In this state, you can choose to disconnect the setup to come back at a later time. 在练习直播事件时,这种状态非常有用。This is useful when practicing for your live event.

可以停止并重新启动事件吗?Can I stop and restart my event?

如果事件处于直播就绪状态,则可以断开连接。If you are in the pre-live state of your event, you can disconnect the event. 这样做需要重新启动设置过程。By doing so, you will need to restart the set-up process. 这有助于在实际直播事件之前测试事件的设置。This is useful for testing the setup of your event before the actual event. 如果已在直播事件,则无法重新启动广播;停止后,事件将结束。If your event is already live, you cannot restart the broadcast; once stopped, the event will be completed.

可以重新连接编码器吗?Can I reconnect my encoder?

可以,如果由于某种原因断开了编码器的连接,只要对给定的设置使用相同的输出配置文件,就可以重新连接(如果编码器支持此功能)。Yes, if you disconnect your encoder for some reason, you can reconnect if the encoder supports this functionality, so long as you use the same output profile for a given setup. 如果处于直播就绪状态,可以从 Microsoft Stream 中断开设置的连接以发送新的输出,但必须再次启动设置。If you are in pre-live, you may disconnect your setup from within Microsoft Stream to send a new output, but you must start the setup again. 如果事件已经结束,则无法重新连接。It is not possible if your event is already completed. 如果编码器断开连接的时间过长,则事件将自动从直播就绪转换为离线状态(可以再次启动设置),或从直播转换为结束(此时事件将结束且无法重新启动)。If your encoder is disconnected for too long, the event will either automatically transition from pre-live to offline (you can start setup again), or from live to ended (the event will be complete at this point and cannot be restarted). 注意,如果未正确连接编码器,可能会给观众带来糟糕的观看体验或显示错误。Note, your audience may have a bad viewing experience or see errors if your encoder is not connected properly.

事件结束后,视频会发生什么情况?What happens to my video after the event ends?

制作者停止事件后,可以立即在 Microsoft Stream 中按需点播观看该事件。Once the event is stopped by the producer, it is immediately available for viewing on-demand in Microsoft Stream. 如果选择了这些选项,自动语音转文本和面部检测将开始处理。If the options are selected, the automatic speech-to-text and facial detection will start processing. 所有者还可以下载视频。The video will also be downloadable by an owner. 现可使用 Microsoft Stream 注释。Microsoft Stream comments will now be available for use.

直播事件的最大时长是多久?How long can my live event be?

对于预览版,直播事件的最大时长是 4 个小时。At preview, the maximum length of a live event is 4 hours.

事件自动停止是怎么回事?My event automatically stopped, what's going on?

达到直播事件的最大时长后,将自动停止事件供按需点播观看。After the maximum length of a live event has been reached, it will automatically stop the event and will become available for on-demand consumption.

现实生活和在线直播事件之间是否存在延迟?Is there a lag between real life and the online live event?

是的,在线直播事件会出现时间延迟的情况。Yes, there is a time delay that will be seen on the online live event.

可以在另一个网站中嵌入直播事件吗?Can I embed the live event in another site?

可以,和 Microsoft Stream 中的所有其他视频一样,你可以使用嵌入代码轻松在任何网站上嵌入直播事件。Yes, just like all other videos in Microsoft Stream, you can easily embed the live event on any website using the embed code. 还可以与 Microsoft Teams、Yammer 和 SharePoint 更深入地集成,实现简单的嵌入操作。There are also deeper integrations with Microsoft Teams, Yammer, and SharePoint that allow simple embedding. 只有有权查看直播事件的查看者才能观看。Only viewers who have permissions to view the live event will be able to watch it.

直播流好像出现了问题,该怎么办?There seems to be an issue with my live stream, what do I do?

通常情况下,如果能够正确连接到直播事件,那么就可能是编码器的问题。Commonly, if you are able to correctly connect to the live event, there may be an issue with the encoder. 首先检查编码器是否已连接并正确进行流式传输。Start by checking that your encoder is connected and streaming correctly. 高 CPU 负载或带宽限制会导致直播事件出现问题。High CPU load or bandwidth constraints can cause issues with your live event.

为什么在 Microsoft Stream 中看不到 Microsoft Teams 内创建的快速启动事件?Why can't I see the Quick start events that I created in Microsoft Teams in Microsoft Stream?

目前,Microsoft Stream 不支持此制作者流。Currently, this producer flow is not powered by Microsoft Stream. 若要在 Stream 中查看事件,待事件结束后,只需将下载的录制内容上传到 Microsoft Stream 中即可。To see your events in Stream, after the event is completed, simply upload the downloaded recording into Microsoft Stream.

支持何种实时字幕格式?What live captions format do you support?

Stream 支持 CEA 708 嵌入式字幕Stream supports CEA 708 embedded captions

如何将实时字幕添加到我的事件?How can I add live captions to my events?

如果使用支持 CEA 708 嵌入式字幕的编码器,并使用 stenographer 或其他方法生成字幕,Stream 将自动检测这些字幕并允许监视事件的人员开启或关闭字幕,以及配置与点播视频字幕一样的外观和感觉。If you're using an encoder that supports embedded CEA 708 captions and are generating captions using a stenographer or other method, Stream will automatically detect the captions and allow the people watching the event to toggle them on or off as well as configure the look and feel of them, same as the on demand video captions. 结束实时事件后,可按原样保留生成的实时字幕或将干净版字幕作为覆盖原始版本的 VTT 上传。When your live event is over, you can chose to keep the generated live captions as is or upload a cleaned up version of the captions as a VTT which will overwrite the original.
