我尝试安装pHash,但当我执行./configure
时,会返回此消息:
...
*** Configuring video Hash ***
checking whether FFmpeg is present... checking for avcodec_alloc_frame in -lavcodec... no
configure: error:
*** libavcodec not found.
You need FFmpeg. Get it at <http://ffmpeg.org/>
但FFMPEG已正确安装,实际上正在执行ffmpeg
它返回:
ffmpeg version 3.0.2 Copyright (c) 2000-2016 the FFmpeg developers
built with gcc 4.8 (Ubuntu 4.8.4-2ubuntu1~14.04.1)

Hyper fast Audio and Video encoder

Use -h to get full help or, even better, run 'man ffmpeg'
为什么会这样?
答案 0 :(得分:0)
不幸的是,我没有在Ubuntu 15上解决问题。我安装了Ubuntu 16(再次包括FFMPEG),一切都很顺利。
