• ERROR : dav1d >= 0.2.1 not found using pkg-config

  24 avril 2020, par Dmitry Maksakov

  I am trying to build ffmpeg with dav1d. I've successfully built davit using the following commands :

  



  git clone --depth=1 https://code.videolan.org/videolan/dav1d.git && \
cd dav1d && \
mkdir build && cd build && \
meson .. && \
ninja


  



  After that, I am running a config command for the FFmpeg and get the error :

  



  PKG_CONFIG_PATH="/app/ffmpeg_build/lib/pkgconfig" ./configure \
    --prefix="/app/ffmpeg_build" \
    --pkg-config-flags="--static" \
    --extra-cflags="-I/app/ffmpeg_build/include" \
    --extra-ldflags="-L/app/ffmpeg_build/lib" \
    --extra-libs="-lpthread -lm" \
    --bindir="/usr/local/bin" \
    --enable-gpl \
    --enable-libass \
    --enable-libmp3lame \
    --enable-libfreetype \
    --enable-libopus \
    --enable-libvorbis \
    --enable-libx264 \
    --enable-libdav1d \
    --enable-nonfree


  



  (All other libs are installed and FFmpeg configures and builds correctly with them if I omit --enable-libdav1d, but in case of the above command I get) :

  



  ERROR: dav1d >= 0.2.1 not found using pkg-config


  



  I think the reason could be that meson puts bin files in the wrong directory. Could anyone please help ?

  



  P.S. I am using Ubuntu 18.04.

  



  Example of build commands for the other libs :

  



  git -C x264 pull 2> /dev/null || git clone --depth 1 https://code.videolan.org/videolan/x264.git && \
cd x264 && \
PKG_CONFIG_PATH="/app/ffmpeg_build/lib/pkgconfig" ./configure --prefix="/app/ffmpeg_build" --bindir="/usr/local/bin" --enable-static --enable-pic && \
make && \
make install

• FFMPEG won't configure for iPhone

  5 août 2016, par iSkythe

  I have downloaded FFMPEG via svn, and put the gas-preprocessor into usr/local/bin. But, when I try to post the following code into terminal, it says : -bash: ./configure: No such file or directory

  This is the code :

  ./configure
  —cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc —as=’gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc’
  —sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.sdk —enable-cross-compile —target-os=darwin —arch=arm —cpu=arm1176jzf-s —disable-pic —enable-gpl —enable-postproc —disable-debug —disable-stripping —enable-avfilter —enable-avfilter-lavf —extra-cflags=’-arch armv6’ —extra-ldflags=’-arch armv6’

  I am using Snow Leopard 10.6.1. What am I doing wrong ?
