    It is a video decoding package and can be installed with sudo apt-get install libx264-142 libx264-dev

It happens because you are compiling libav with --enable-libx264 which would need the libx264 headers to complete. It fails at the configure phase with:

configure: error: libx264 not found

This can be fixed easily installing the needed headers package libx264-dev which should be done with sudo apt-get install yasm libvpx. libx264. but for some reason it doesn't for you:

sudo apt-get install yasm libvpx. libx264.

libvpx-dev is already the newest version.
libvpx1 is already the newest version.
libvpx1 set to manually installed.
yasm is already the newest version.
libx264-142 is already the newest version.
libx264-142 set to manually installed.
libx264-dev is already the newest version.
The following NEW packages will be installed:

  • @Braiam I'm going to compile ffmpeg for ARM processor. So I can't install it as that way, because that way install for my PC. I should add compiled x264 folder for ARM, in ./configure command; I added this like: --extra-cflags="-I../x264" --extra-ldflags="-L../x264"; But seems doesn't work.

  • @Mr.Hyde I'm not knowledgeable about ARM's builds but don't you have a -dev package that includes those headers? IMO, ffmpeg configure script should find it.

include --enable-static --disable-opencl

eg -

cd ~/ffmpeg_sources
wget http://download.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar xjvf last_x264.tar.bz2
cd x264-snapshot*
PATH="$PATH:$HOME/bin" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static **--disable-opencl**
PATH="$PATH:$HOME/bin" make
make install
make distclean

  • This installs libx264 from source, though you should usually use the package manager to install software.

AS 123456 said use sudo apt-get install libx264-142 libx264-dev

This will install the libx264 that gave you the error.
