• "ERROR : libopencv not found" when compiling ffmpeg

  13 avril 2023, par ArnoBen

  I am trying to install ffmpeg with the libopencv libraries and it fails with the error "ERROR : libopencv not found".

  


  I did install libopencv with sudo apt install libopencv-dev which now prints libopencv-dev is already the newest version (3.2.0+dfsg-4ubuntu0.1), and I can see the files in /usr/include/opencv2.

  


  Here is my full script to compile ffmpeg :

  


  cd ~/ffmpeg_sources && \
wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && \
tar xjvf ffmpeg-snapshot.tar.bz2 && \
cd ffmpeg && \
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
  --prefix="$HOME/ffmpeg_build" \
  --pkg-config-flags="--static" \
  --extra-cflags="-I$HOME/ffmpeg_build/include" \
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
  --extra-libs="-lpthread -lm" \
  --ld="g++" \
  --bindir="$HOME/bin" \
  --enable-gpl \
  --enable-gnutls \
  --enable-libopencv \
  --enable-libtensorflow \
  --enable-libx264 \
  --enable-libfdk-aac \
  --enable-nonfree && \
PATH="$HOME/bin:$PATH" make -j4 && \
make -j4 install && \
hash -r


  


  It works fine if I remove the --enable-libopencv line.

  


  I'm running Ubuntu 18.04.6.

  


  Any help would be appreciated.
