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

  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

  I’m using a cygwin64 build of ffmpeg (1, 2) to burn subtitles into a video file as follows :

  [Parsed_subtitles_0 @ 0x6000229c0] Neither PlayResX nor PlayResY defined. Assuming 384x288

  But the subtitles do not appear in the resulting video stream at all.

  The [Parsed_subtitles_0 @ 0x6000229c0] Neither PlayResX nor PlayResY defined. Assuming 384x288 warning is not a part of the problem, as converting the subtitles to .ass via ffmpeg -i file.srt file.ass and specifying the PlayResX and Y values makes the warning disappear without solving the original issue.

  I know that the libass library, which provides the subtitles filter to ffmpeg, uses fontconfig, which is known not to work out-of-box under windows. However, the lack of any fontconfig warnings makes me believe that this is not the problem here. Any leads as to what might the cause of the problem be ?

  EDIT : I have downloaded and compiled ffmpeg myself :

  $ git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
  
  $ cd ffmpeg
  
  $ ./configure --enable-static --disable-shared --enable-libass
  
  $ make

  The output of the conversion ./ffmpeg -i file.mp4 -vf subtitles=file.srt file.ts is identical except for the fact that no warning messages get printed this time around. I’m looking into whether the fontconfig library configuration could be the culprit.
