• compiling ffmpeg 2.3 for android with NDK r10 on windows [duplicate]

  25 août 2014, par L.Grillo

  This question already has an answer here :

  • How to compile ffmpeg-2.2.2 on windows with cygwin and android ndk r9c
    
    1 answer
    

  After a week i’m trying to compile ffmpeg for android.
  I can’t find a static build in the entire web exept for https://github.com/guardianproject/android-ffmpeg-java/tree/master/res/raw but is 0.11 version one.

  This is my build.sh

  #!/usr/bin/env bash
  
  
  
  NDK=C:/Android/android-ndk-r10
  
  SYSROOT=$NDK/platforms/android-18/arch-arm/
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/windows-x86_64
  
  
  
  function build_one
  
  {
  
  ./configure \
  
      --arch=arm \
  
      --target-os=linux \
  
      --enable-runtime-cpudetect \
  
      --enable-pic \
  
      --disable-shared \
  
      --enable-static \
  
      --extra-cflags='-march=armv6' \
  
      --extra-ldflags="$ADDI_LDFLAGS" \
  
      --enable-ffmpeg \
  
      --disable-ffplay \
  
      --disable-ffprobe \
  
      --disable-ffserver\
  
      --disable-network \
  
      --enable-cross-compile \
  
      --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
      --sysroot=$SYSROOT \
  
      $ADDITIONAL_CONFIGURE_FLAG
  
  make clean
  
  make -j4
  
  make install
  
  }
  
  
  
  CPU=arm
  
  PREFIX=$(pwd)/android/$CPU
  
  ADDI_CFLAGS="-marm"
  
  
  
  build_one

  It seems everything works good except the compilation stopped after 4 files :

  

  It seems to stay here forever. After 4 hours nothing is moving.
  the process "make.exe (32 bit)" is running with 18% of cpu

  Any help will be precious.
  Thank u

• Reduce compiled ffmpeg library size based on what I need

  20 septembre 2014, par Alin

  I finally managed to build ffmpeg as detailed in here : https://enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/ and in the end, I have a ffmpeg library which accepts command arguments.

  I am ONLY applying a watermark image over the video so for it I am using this ffmpeg command :

  ffmpeg -i input.avi -i logo.png -filter_complex 'overlay=10:main_h-overlay_h-10' output.avi

  Basic config :

    ./configure \
  
      --prefix=$PREFIX \
  
      --disable-shared \
  
      --enable-static \
  
      --disable-doc \
  
      --disable-ffmpeg \
  
      --disable-ffplay \
  
      --disable-ffprobe \
  
      --disable-ffserver \
  
      --disable-doc \
  
      --disable-symver \
  
      --enable-protocol=concat \
  
      --enable-protocol=file \
  
      --enable-muxer=mp4 \
  
      --enable-demuxer=mpegts \
  
      --enable-memalign-hack \
  
      --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
      --target-os=linux \
  
      --arch=arm \
  
      --enable-cross-compile \
  
      --sysroot=$SYSROOT \
  
      --extra-cflags="-Os -fpic -marm $ADDI_CFLAGS" \
  
      --extra-ldflags="$ADDI_LDFLAGS"

  No other commands needed from ffmpeg.

  When compiling ffmpeg I get these files :

  

  I want to reduce the size of the library to as small as possible, so given the above command, are there any files that I can remove from final build ?

  ALSO which is the most common CPU found in current devices ? arm v7vfpv3, arm v7vfp, arm v7n ? I want to cover as many devices as possible.

  #arm v6
  
  #CPU=armv6
  
  #OPTIMIZE_CFLAGS="-marm -march=$CPU"
  
  #PREFIX=./android/$CPU 
  
  #ADDITIONAL_CONFIGURE_FLAG=
  
  #build_one
  
  
  
  #arm v7vfpv3
  
  CPU=armv7-a
  
  OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=vfpv3-d16 -marm -march=$CPU "
  
  PREFIX=./android/$CPU
  
  ADDITIONAL_CONFIGURE_FLAG=

  #build_one
