• How to resolve "ERROR : libx264 not found" ?

  16 mars 2016, par user3665376

  I needed to install ffmpeg with libx264 support for enabling H.264 encoding . I installed libx264 successfully using the below script with toolchains available in android-ndk-r9d .

   #!/bin/bash
  
   NDK=~/android-ndk-r9d
  
   SYSROOT=$NDK/platforms/android-8/arch-arm/
  
   TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
  
   function build_one
  
   {
  
   ./configure \
  
   --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
   --sysroot="$SYSROOT" \
  
   --host=arm-linux \
  
   --enable-pic \
  
   --enable-shared \
  
   --disable-cli
  
   make clean
  
   make
  
   make install
  
   }
  
   build_one 

  Now I wanted to build ffmpeg with libx264 support . I used the below script with —enable-libx264 , —enable-nonfree , —enable-gpl options as in the below script .

  #!/bin/bash
  
  NDK=~/android-ndk-r9d
  
  SYSROOT=$NDK/platforms/android-8/arch-arm/
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
  
  function build_one
  
  {
  
  ./configure \
  
  --prefix=$PREFIX \
  
  --enable-shared \
  
  --enable-nonfree \
  
  --enable-gpl \
  
  --enable-libx264 \
  
  --disable-doc \
  
  --disable-ffmpeg \
  
  --disable-ffplay \
  
  --disable-ffprobe \
  
  --disable-ffserver \
  
  --disable-avdevice \
  
  --disable-doc \
  
  --disable-symver \
  
  --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
  --target-os=linux \
  
  --arch=arm \
  
  --enable-cross-compile \
  
  --sysroot=$SYSROOT \
  
  --extra-cflags="-Os -fpic $ADDI_CFLAGS" \
  
  --extra-ldflags="$ADDI_LDFLAGS" \
  
  $ADDITIONAL_CONFIGURE_FLAG
  
  make clean
  
  make
  
  make install
  
  }
  
  CPU=arm
  
  PREFIX=$(pwd)/android/$CPU
  
  ADDI_CFLAGS="-marm"
  
  build_one

  But when I run the script I’m getting error "ERROR : libx264 not found" .

  I suppose ffmpeg is not able to figure out the installed location of libx264 . After libx264 installation I have libx264.so file in /usr/local/lib executable at /usr/local/bin and header files at /usr/local/include directories .

  What all changes do I need to make to the ffmpeg build script in-order to make it detect libx264 ?

  Note : I am using Ubuntu 12.04(64 bit) for cross compiling .

• ‘ffbuild/library.mak : No such file or directory’ on building ffmpeg for android

  20 octobre 2022, par JustinGong

  I use ffmpeg-5.1 and android-ndk-r22b in buntu 20.04.4 LTS system for building ffmpeg for android.

  


  Firstly, under ffmpeg-5.1 dir, I run ./configure --disable-x86asm.

  


  Second, I run sh build_android_clang.sh, it shows error :

  


  Makefile:113: ffbuild/library.mak: No such file or directory
make: *** No rule to make target 'ffbuild/library.mak'.  Stop.
Makefile:113: ffbuild/library.mak: No such file or directory
make: *** No rule to make target 'ffbuild/library.mak'.  Stop.
Makefile:113: ffbuild/library.mak: No such file or directory
make: *** No rule to make target 'ffbuild/library.mak'.  Stop.


  


  How to fix it ? Can anyone give some advises ?

  


  The content of build_android_clang.sh is as follows :
