  • compile ffmpeg on ec2 linux instance - no libfdk-acc available

    11 mai 2022, par byc

    I’m compiling the ffmpeg on an ec2 amazon linux instance, but it threw me an error ERROR: libfdk_aac not found.

    &#xA;

    I'm following this guide http://trac.ffmpeg.org/wiki/CompilationGuide/Centos to first install the dependencies and compile the package.

    &#xA;

    yum install autoconf automake bzip2 bzip2-devel cmake freetype-devel gcc gcc-c&#x2B;&#x2B; git libtool make pkgconfig zlib-devel&#xA;&#xA;mkdir ~/ffmpeg_sources&#xA;&#xA;cd ~/ffmpeg_sources&#xA;curl -O -L https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2&#xA;tar xjvf ffmpeg-snapshot.tar.bz2&#xA;cd ffmpeg&#xA;PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \&#xA;  --prefix="$HOME/ffmpeg_build" \&#xA;  --pkg-config-flags="--static" \&#xA;  --extra-cflags="-I$HOME/ffmpeg_build/include" \&#xA;  --extra-ldflags="-L$HOME/ffmpeg_build/lib" \&#xA;  --extra-libs=-lpthread \&#xA;  --extra-libs=-lm \&#xA;  --bindir="$HOME/bin" \&#xA;  --enable-gpl \&#xA;  --enable-libfdk_aac \&#xA;  --enable-libfreetype \&#xA;  --enable-libmp3lame \&#xA;  --enable-libopus \&#xA;  --enable-libvpx \&#xA;  --enable-libx264 \&#xA;  --enable-libx265 \&#xA;  --enable-nonfree&#xA;make&#xA;make install&#xA;hash -d ffmpeg&#xA;

    &#xA;

    and this is the error message I've got

    &#xA;

    &#xA;

    I tried installing libfdk_aac but there's no package found. I don't seem to come across any posts discussing this issue, or at least recently. Appreciate any pointers. thanks !

  • Issue #1 when compiling Xuggler for Raspberry pi with libspeex

    23 juillet 2014, par Ashish Sharma

    I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian),

    I followed the ’Basic Build Instructions’ available here for compiling Xuggler.

    After I successfully installed all the prerequisites and set the correct paths, I ran the following command :

    ant run-tests

    After sometime I am facing the following error and the ant build fails :
