Svt av1 ffmpeg

FFmpeg 2.8.17 "Feynman" 2.8.17 was released on 2020-07-07. It is the latest stable FFmpeg release from the 2.8 release branch, which was cut from master on 2015-09-05.

尽管如此cpu / gpu加速编码一直是质量较低的，我们将很有趣地看到svt-av1的输出质量如何与ffmpeg进行比较。即使svt-av1将av1编码的成本降低到更低的水平，目前也还不清楚这是否能促进av1的使用超过目前从事av1相关工作的早期采用者（主要是aom联盟成员）。

SVT-AV1 uses the Open type by default and the resulting videos in the previous SVT-AV1 GUI versions would have problems seeking. This is now solved by this new option. Additionally, this version have the following improvements: The First pass encoding will be skipped if the software was interrupted while performing the second pass encode.

I recently did some encoding, but settled on VP9 over AV1 because it has wider support and ffmpeg considers its encoder "experimental." VP9 is supported out-of-the-box on practically everything modern that isn't Apple. AV1 is on-track to replace it, but depending on the support you're looking for, that might be five years out.
