I have installed ffmpeg 4.0.2 still gives error You need FFmpeg

OK, old thread.

First, it will not work with ffmepg >= 4.

Second, to properly link, at least on linux, issue: CPPFLAGS="$( pkg-config --cflags libavcodec libavutil )" CFLAGS="$( pkg-config --cflags libavcodec libavutil )" LIBS="$( pkg-config --libs libavcodec libavutil )" ./configure

Third, if you don't need video support, disable it using: ./configure --disable-video-hash

Hey @andrecbarros, this didn't work for me. pkg-config commands are working but it still complaints that ffmpeg not found.

On which system are you testing it? Can, you post the error line of ./configure here?
