我刚刚安装ffmpeg了frei0r吉安但由于某种原因，我似乎无法使用它（这是在 Windows 上）。
当使用此命令时：
ffmpeg -i input.mp4 -filter:v frei0r=pixeliz0r=0.02:0.02 output.mp4
我收到此错误：
[Parsed_frei0r_0 @ 000001ecbb32c240] Option 'pixeliz0r' not found
[AVFilterGraph @ 000001ecba7e3a40] Error initializing filter 'frei0r' with args 'pixeliz0r=0.02:0.02'
Error reinitializing filters!
Failed to inject frame into filter network: Option not found
Error while processing the decoded data for stream #0:0

那么为什么会发生此错误？我也尝试使用glow，但出现了同样的错误。其他库工作正常，我尝试重新安装。

旧语法已更改。使用：
ffmpeg -i input -vf "frei0r=filter_name=pixeliz0r:filter_params=0.02|0.02" output
