FFmpeg 9.0

FFmpeg 9.0来了，这次最大亮点是给这款老牌视频处理工具装上了GPU加速引擎，处理视频的速度大幅提升，堪称视频剪辑界的“涡轮增压”。简单说，FFmpeg就像是视频文件背后的万能格式转换器，平时你用手机剪辑、看各种格式的影片，背后都有它的身影。过去它主要靠CPU计算，面对高清4K、8K视频就像用小水管运水，又慢又吃力。新版引入了Vulkan技术，相当于直接把水管换成大口径，让GPU显卡也参与干活，复杂特效处理和视频转码都变得飞快。对普通人来说，这意味着以后用视频软件剪辑、转格式时，等待进度条的时间会明显缩短，手机上处理高清视频也不容易卡顿了。很多播放器和剪辑工具底层都依赖FFmpeg，它们的升级也会让用户体验水涨船高。当然，这项更新主要影响开发者，普通用户可能感知不到变化，但大家日常用的视频工具会越来越流畅、强大。贝塞尔曲线、动态模糊这些高级特效，以后在普通设备上也能丝滑运转了。
