Need FFMPEG for Android

[Giuseppe]

I am not expert with C code, so I need some help to find the .so library already compiled and to just use in my Android project.

Some help?

[Peter Arwanitis]

Hi Guiseppe,

you will find compiled ffmpeg libs as part of the JavaCV project:

http://code.google.com/p/javacv/downloads/list 

hope that this is what you are looking for

Compiled for what arch?

It's going to be easier if you compile the library yourself, you don't have to be an expert C programmer to do that.

Try this .It explains how to cross compile the ffmpeg.Once compiled you will get the standard .so like 

libavcodec.so,libavformat.so, libavutil.so, lib,libjpeg.so ,libpostproc.so,libavfilter.so .libavcore.so,libswscale and libavdevice.so.Copy them in the JNI folder and modify the android.mk file to include  all the above lib*.so in one common*.so say your-list of shared-lib-name

The Android.mk file will look like this : 

#ffmpeg pre-built modules

include $(CLEAR_VARS)

LOCAL_MODULE := myffmpeg1

LOCAL_SRC_FILES := libavcodec.so

include $(PREBUILT_SHARED_LIBRARY)

#ffmpeg pre-built modules

include $(CLEAR_VARS)

LOCAL_MODULE := myffmpeg2

LOCAL_SRC_FILES := libavcore.so

include $(PREBUILT_SHARED_LIBRARY)

#ffmpeg pre-built modules

include $(CLEAR_VARS)

LOCAL_MODULE := myffmpeg3

LOCAL_SRC_FILES := libavfilter.so

include $(PREBUILT_SHARED_LIBRARY)

#ffmpeg pre-built modules

include $(CLEAR_VARS)

LOCAL_MODULE := myffmpeg4

LOCAL_SRC_FILES := libavformat.so

include $(PREBUILT_SHARED_LIBRARY)

#ffmpeg pre-built modules

include $(CLEAR_VARS)

LOCAL_MODULE := myffmpeg5

LOCAL_SRC_FILES := libavutil.so

include $(PREBUILT_SHARED_LIBRARY)

#ffmpeg pre-built modules

include $(CLEAR_VARS)

LOCAL_MODULE := myffmpeg6

LOCAL_SRC_FILES := libswscale.so

include $(PREBUILT_SHARED_LIBRARY)

#ffmpeg pre-built modules

include $(CLEAR_VARS)

LOCAL_MODULE := myffmpeg7

LOCAL_SRC_FILES := libavdevice.so

include $(PREBUILT_SHARED_LIBRARY)

#ffmpeg pre-built modules

#include $(CLEAR_VARS)

#LOCAL_MODULE := myffmpeg8

#LOCAL_SRC_FILES := libpostproc.so

#include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)

LOCAL_MODULE    := your-list of shared-lib-name

LOCAL_SHARED_LIBRARIES :=  myffmpeg1 myffmpeg2 myffmpeg3 myffmpeg4 myffmpeg5 myffmpeg6 myffmpeg7 

LOCAL_SRC_FILES := your-list of source-files

# No special compiler flags.

LOCAL_CFLAGS += -fno-builtin-printf -static -O3 -DCORE_FREQ=800 -DLINUX

LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog -L--soname-prefix=/system/lib/ 

include $(BUILD_SHARED_LIBRARY)

you will get your-list of source-files.so which you can load by System.load("name of .so") and use can call the functions using the native jni calls.

Hi Jessica,

I tried to follow the link you give me, but this is for Linux plattform, I am working on Windows.

Do you have this job already done with sources?

Thank you,

Giuseppe

[s.rawat]

We have done it with the Linux/Android platform But I think you can do the similar job on windows as well.how far have you succeeded?.What have you tried so far.What is the blocking point?
