class="" style="font-size: 14px;line-height: 1.8;letter-spacing: 1.2px;box-sizing: border-box;"><p style="box-sizing: border-box;">我们先来理解一下“资源不足”的原因：<span style="color: rgb(255, 129, 36);box-sizing: border-box;">解码显示性能达到了设备的上限</span>，每一个产品，都有其性能的上限。</p><p style="box-sizing: border-box;">本地解码性能指的是录像机 将前端摄像机图像显示出来的最大能力，超过了就会提示“资源不足”。<br style="box-sizing: border-box;"></p><p style="box-sizing: border-box;">首先，我们先来看一下设备的取流机制:</p><p style="box-sizing: border-box;"><span style="color: rgb(255, 129, 36);box-sizing: border-box;">当我们的录像机连接前端相机时，默认都会尝试获取2路视频，即主码流+子码流。</span></p><p style="box-sizing: border-box;">主码流的分辨率与码率比子码流大，即高清的视频源，子码流为辅流，清晰度和码率相对较小。</p><p style="box-sizing: border-box;">NVR 本地取流机制如下图所示：</p></section></section></section></section></section></section><section class="Powered-by-XIUMI V5" style="box-sizing: border-box;" powered-by="xiumi.us"><section class=""

style="box-sizing: border-box;">总结可以看出：</p><p style="box-sizing: border-box;"><strong style="box-sizing: border-box;">在多画面分割预览的情况下，设备主要是以取子码流在解码，</strong>理论上，在不是取子码流很大的情况下，是不会资源不足的。</p></section></section></section></section></section></section><section class="Powered-by-XIUMI V5" style="box-sizing:
