• Trying to use FFMPEG for android. Compiling but still not working

  15 avril 2014, par Austin Mueller

  So to start off... Im trying to use ffmpeg to compile an array of images into a video on Android.

  I have followed a variety of tutorials online and have gotten as far as being able to compile the lib for Android and still have to project run.
  The repo im now using can be found here : https://github.com/Batterii/android-ffmpeg-x264

  I made a couple tweaks to the setttings.sh just to correct ndk location. Besides that, I followed the instructions and it seemed to work flawlessly.

  After that, I converted the "Project" project into an Android stdio library module.
  

  I am not getting any compile errors, nor am I getting any runtime errors, or any other errors that I can detect... Nothing on logcat... But I am definitely not getting any video called out.mp4.
  In an onCreate of a particular activity, I am running this code :

  Videokit vk = new Videokit();
  
  vk.run(new String[]{"ffmpeg", "-r", "1/5", "-i", "%d.jpg", "-c:v", "libx264", "-r", "30", "-pix_fmt", "yuv420p", project.getProjectDirectory() + "/out.mp4"});

  This command is taken from the command line example found here :
  https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images

  Thank you in advance for anyone taking the time to look through this post... I am pretty baffled at this point, as there are no errors I can find and no video...
  Thanks

  Update

  Turns out it is not actually compiling correctly... but i have found a few things.
  here is the make file from the Eclipse version of the project

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE  := videokit
  
  # These need to be in the right order
  
  FFMPEG_LIBS := $(addprefix ffmpeg/, \
  
   libavdevice/libavdevice.a \
  
   libavformat/libavformat.a \
  
   libavfilter/libavfilter.a \
  
   libavcodec/libavcodec.a \
  
   libswscale/libswscale.a \
  
   libavutil/libavutil.a \
  
   libswresample/libswresample.a \
  
   libpostproc/libpostproc.a )
  
  # ffmpeg uses its own deprecated functions liberally, so turn off that annoying noise
  
  LOCAL_CFLAGS += -g -Iffmpeg -Ivideokit -Wno-deprecated-declarations 
  
  LOCAL_LDLIBS += -llog -lz $(FFMPEG_LIBS) x264/libx264.a
  
  LOCAL_SRC_FILES :=  ffmpeg/cmdutils.c ffmpeg/ffmpeg.c videokit/uk_co_halfninja_videokit_Videokit.c
  
  include $(BUILD_SHARED_LIBRARY)

  and here is the make file that gradle is auto-generating for me... thanks to Android Studio...

  LOCAL_PATH := $(call my-dir)
  
  include $(CLEAR_VARS)
  
  
  
  LOCAL_MODULE := videokit

  LOCAL_C_INCLUDES += Project/Module/src/arm/jni
  
  LOCAL_C_INCLUDES += Project/Module/src/debug/jni
  
  LOCAL_C_INCLUDES += Project/Module/src/armDebug/jni
  
  
  
  include $(BUILD_SHARED_LIBRARY)

  And finally, here is my build.gradle

      compile 'com.android.support:support-v4:19.0.0'
  
      compile fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
  
  }

  As you can see, my build.gradle generates something that is pretty close to the original... but not the same. When i try to run/compile it, gradle spits this out

  I've been messing around with it for a couple hours now and pretty much every time, i get gradle yelling at me about the fact that it can't find some file. I'm beginning to think that maybe it is because my LOCAL_LDLIBS aren't in the same order as the original...? Im not entirely sure... Does anyone else have any ideas...?

  avcodec/ac3 : rename identifier used to select the fixed point variant
  the CONFIG_ prefix is used by configure, using it for other things
