据悉，AV1 开源视频编解码器专为超高清分辨率、宽色域和高动态范围的增强体验而设计。早在 2018 年，AOMedia 就宣称 AV1 效率较现有编解码器提升 30%（尤其针对 H.265 \/ HEVC 的类似 4K + 内容设计）。 不过高效编解码器的一个问题，就是相当高的资源开销、且通常需要依赖于硬件加速才能正常工作。与此同时，现代 CPU 拥有大量资源和可用于编解码的新指令集，这正是英特尔 SVT-AV1 可以派上用场的地方。 英特尔指出，SVT-AV1 是一个可扩展的、且与标准无关的编解码器库，可充分发挥现代 CPU \/ AVX2 指令的多线程性能。 此外 Phoronix 指出，SVT-A11 提供了针对 AVX2 的进一步优化，可带来性能和图像质量改进、更多预设级别的快速解码、以及 S 帧支持。 无论你的现代 x86 计算机运行的是 苹果 macOS、 微软 Windows 、还是开源的 Linux 操作系统，新编解码器都可以在英特尔 5 代酷睿（Broadwell 及以上）处理器上良好支持。 起初英特尔与流媒体平台 Netflix 启动了 SVT-AV1 项目，验证了 AV1 编解码器能够适用于从优质视频点播、到实时编 \/…
