• Android - Integrating ffmpeg and android-ndk-r9c

  16 juillet 2015, par lgdroid57

  I have seen a lot of posts about FFmpeg and using FFmpeg in Android, but I am finding that a majority of these posts are for older versions of either FFmpeg or Android NDK. I was able to get a result from https://github.com/mconf/android-ffmpeg, which includes the files : "libavcodec.so", "libavformat.so", "libavutil.so", "libswscale.so". However, simply adding these files to my project does not seem to be enough to use FFmpeg. (I followed http://stackoverflow.com/a/21773572/1877798 as a reference guide). It’s possible that either I’ve done something wrong in configuring these files in my project, or I’ve done something wrong in building FFmpeg for Android. (Should there be more files ?)

  I was wondering if there are any recent guides for building or integrating FFmpeg in an Android project. I am using FFmpeg (as of 2/27/14) and Android NDK 9c.
  If not, does anyone have other recommendations for other libraries ? I am trying to take a set of image files and create a video/animated gif programatically.

  Thanks ! :-)

   EDIT 

  I have found http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/comment-page-4/ and a couple others found on GitHub. However, they all seem to struggle in building FFmpeg. I am using Mac OS X

  Here is my script :

  #!/bin/bash
  
  NDK=/Downloads/android-ndk-r9c
  
  SYSROOT=$NDK/platforms/android-18/arch-arm/
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/darwin-x86_64
  
  # Note: Change the TOOLCHAIN to match that available for your host system.
  
  # darwin-x86_64 is for Mac OS X, but you knew that.
  
  function build_one
  
  {
  
  ./configure \
  
      --prefix=$PREFIX \
  
      --enable-shared \
  
      --disable-static \
  
      --disable-doc \
  
      --disable-programs \
  
      --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

  Here is the log :

  Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-        dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/c++/4.2.1

  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

  libavcodec/qsvenc : fix a memory leak problem
  "qf->frame" ref to input frame but it isn't released. av_frame_unref()
  
  is added before refering qf->frame to new frame to make sure the previous
  
  reference is released.
