perl - 在 windows xp 上安装 ffmpeg(perl 包)

Question

我正在尝试安装 ffmpeg通过在我的命令提示符下键入“cpan install FFmpeg”。我已经安装了 Image::Magick、Image::PBM、Image::Magick::Iterator，据我所知，这是我需要的一些先决条件，但似乎这还不够。 Here's一些额外的信息。我收到错误消息:

Note (probably harmless): No library found for -lavcodec
Note (probably harmless): No library found for -lavformat
Note (probably harmless): No library found for -lz

In file included from ffmpeg.h:2,
             from FFmpeg.xs:16:

./ffmpeg-6036.c:44:21: version.h: No such file or directory
./ffmpeg-6036.c:45:22: cmdutils.h: No such file or directory

我猜我需要安装这些文件并告诉安装程序在哪里可以找到它们。如果这是我需要做的，我该怎么做？

来自 FFmpeg页:

FFmpeg (in this module, referred to here as FFmpeg-Perl) is a Perl interface to the base project FFmpeg (referred to here as FFmpeg-C).

看起来 Perl FFmpeg 模块只是 C 库的包装器。如果您使用的是 MinGW，则可能是您的 MinGW 环境(C 库)中没有安装 FFMpeg。您需要先安装它，然后尝试安装 FFmpeg(Perl 库)再次。
