我试图安装pHash,但是当我执行./configure
返回此消息:FFMPEG安装,但没有找到
...
*** 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/>
但是FFMPEG安装正确,实际上执行ffmpeg
返回:

为什么会发生这种情况?
检查你是否安装了'libavcodec-dev' –
我已经安装了它 – justHelloWorld
你的意思是你刚刚安装了它,或者它已经安装了?它解决了你的问题吗? –
