在windows xp上安装ffmpeg (perl包)

Question

我试图通过在命令提示符中键入"cpan install ffmpeg "来安装ffmpeg。我已经安装了Image::Magick, Image::PBM, Image::Magick::Iterator，我知道，这是我需要的一些先决条件，但似乎这还不够。这里有一些额外的信息。我得到错误信息:

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

./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找到它们。如果这是我需要做的，我该怎么做?

从FFmpeg页面:

FFmpeg(在本模块中称为FFmpeg-Perl)是基本项目FFmpeg(此处称为FFmpeg- c)的Perl接口。

看起来Perl FFmpeg模块只是C库的包装器。如果您正在使用MinGW，可能是因为您的MinGW环境(C库)中没有安装FFMpeg。您需要先安装它，然后再尝试安装FFmpeg (Perl库)。
