使用 AV1 进行视频编码 - FFmpeg答案

【问题标题】：Video encoding with AV1 - FFmpeg使用 AV1 进行视频编码 - FFmpeg

【问题描述】：

我试图用 AV1 对原始视频进行编码。

我用过：ffmpeg -i netflixboxing720p.y4m -c:v libaom-av1 -b:v 500k -strict experimental netflix720p500AV1.mp4

我花了 2 个小时，当我打开创建的视频时，我什么也没得到。我会播放视频。我需要其他命令行吗？

【问题讨论】：

你是如何播放文件的？你试过ffplay吗？
我玩的是 Elmedia 播放器。我确实使用 vp9 和 Hevc 对视频进行了编码。播放文件不是问题。难道是我必须在编码之前安装一些东西吗？
Elmedia 可能不支持 AV1（不要将 AV1 与 AVI 混淆）

标签： video encoding command-line ffmpeg

【解决方案1】：

ffmpeg -i netflixboxing720p.y4m -c:v libaom-av1 -b:v 500k -strict experimental -pix_fmt yuv420p netflix720p500AV1.mp4

试试这个，它可能会奏效。有时当我转换视频时，即使使用 mp4 等常见格式也无法在我的手机上播放，但当我使用 yuv420 转换时它可以工作。
