                         <p>在播放的过程中，观众端可以通过 <codeph><apiname keyref="SetAbrSubscriptionLayer"/></codeph> 设置订阅视频大小流，并可以在大小流之间实现平滑切换。如果对视频体验有更高要求，可以联系<xref keyref="ticket-link"/>开通 ABR（Adaptive Bitrate，自适应码率）功能。启用该功能后，可以自定义不同层级的视频流分辨率，观众可以实现不同分辨率视频流的平滑切换。</p>
                         <p>当网络情况不稳定时，观众端可以调用 <codeph><apiname keyref="SetAbrFallbackLayer"/></codeph> 来设置订阅的视频流的回退选项。SDK 会以你指定的最低质量层级对应的视频流分辨率为下限，在此范围内根据网络状况动态调整分辨率。</p><p props="hide">有关该功能的实现步骤，详见 <xref keyref="rte-player"/>。</p>

         <ul>
             <li>Face shaping: By calling the <codeph><apiname keyref="setFaceShapeBeautyOptions"/></codeph> method, you can enhance various parts of the face. You can use preset templates to achieve effects such as face slimming, eye enlargement, and nose slimming in one go, and fine-tune the overall enhancement intensity. If the preset face shaping effects do not meet your needs, you can call the <codeph><apiname keyref="setFaceShapeAreaOptions"/></codeph> method to set face shaping area options and fine-tune each part of the face for more precise face shaping effects.</li>

     <p>This version adds the <codeph><apiname keyref="setLocalRenderTargetFps"/></codeph> and <codeph><apiname keyref="setRemoteRenderTargetFps"/></codeph> methods, which support setting the maximum frame rate for video rendering locally and remotely. The actual frame rate for video rendering by the SDK will be as close to this value as possible.</p>
     <p>In scenarios where the frame rate requirement for video rendering is not high (e.g., screen sharing, online education) or when the remote end uses mid-to-low-end devices, you can use this set of methods to limit the video rendering frame rate, thereby reducing CPU consumption and improving system performance.</p>

+<li props="cn"><ph><b>Watching live streaming through URLs</b></ph>
     <p>As of this version, audience members can directly open a specific URL to play the real-time media stream through <codeph><apiname keyref="OpenWithUrl"/></codeph>, instead of joining a channel and subscribing to the streams of hosts, which greatly simplifies the API calls for the audience end to watch a live stream.</p>
     <p>During playback, the audience can set the subscription video stream size through <codeph><apiname keyref="SetAbrSubscriptionLayer"/></codeph> and achieve smooth switching between different stream sizes. If higher video experience requirements are needed, you can contact <xref keyref="ticket-link"/> to enable the ABR (Adaptive Bitrate) feature. After enabling this feature, you can customize the resolution of different levels of video streams, allowing the audience to achieve smooth switching between different resolution video streams.</p>
     <p>When the network condition is unstable, the audience can call <codeph><apiname keyref="SetAbrFallbackLayer"/></codeph> to set the fallback options for the subscribed video stream. The SDK will dynamically adjust the resolution within the specified range based on the network condition, with the lowest quality level video stream resolution as the lower limit.</p><p props="hide">For implementation steps of this feature, see <xref keyref="rte-player"/>.</p>
