自动灵活截图下FFmpeg 占用大量CPU | FFmpeg consumes too much CPU in Automatic Flexible Screenshots mode

CPU为 AMD 5800H
使用自动截图模式时，ffmpeg 有时会占用大量CPU和内存导致电脑很卡，推测是因为将图片合并成视频时占用大量资源。希望能加一个开关限制ffmpeg使用核心数或者线程数（内存占用太多没问题CPU占用太多电脑太卡很难受😭）

CPU Model: AMD 5800H
When using Automatic Flexible Screenshots mode, ffmpeg sometimes consume too much CPU and RAM, making my pc lag. I assume it is because ffmpeg needs huge amount of resources to convert screenshots to video. I hope there is a switch to limit CPU cores or thread ffmpeg use.(It's okay for me that ffmpeg uses too much RAM, but high usage of CPU make my computer lag is frustrating 😭)

好反馈！在自动截图模式下 ffmpeg 仅用来将 opencv 合成的大体积视频转码为小体积视频，没想到会这么占用资源😭（我想想有什么办法可以限制ffmpeg的占用……或者可以尝试将此处的压缩格式设置为264+使用显卡nvenc（nvidia）或amf（amd）进行压制（若有（或者勾选节能选项，让电脑仅在无人使用时将截图压制成视频
