ffmpeg 错误与frei0r pixeliz0r 过滤器(重复像素格式)

Question

我在 Linux(Arch)上运行 ffmpeg。
我试着跑

ffmpeg -i input.mp4 -vf frei0r=pixeliz0r output.mp4 

我有这个错误:

[Parsed_frei0r_0 @ 0x5585b8093280] Duplicated pixel format
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0
Conversion failed!

我选择了 --enable-frei0r当我编译时。
ffmpeg 输出:

任何想法如何使它工作？

看起来 vf_frei0r 被 69f5f6ea 破坏了(或者更确切地说，它总是有点坏，但现在有一个检查使它失败)。你可以
