I know this question may be possible duplicate of many others questions but there is no good answer nor a good tutorial available for it
I want to use ffmpeg in my project I am using android ndk7 on windows don't have a clue what ffmpeg code to download,compile tutorial available is for UBUNTU nothing much for windows
I would really appreciate a really good answer.
I was never able to build FFMPEG for Android under Windows but successfully did so under Ubuntu (after having some hard time though).
I used Oracle VM Virtual Box freeware to emulate Ubuntu machine under Windows.
I then built FFMPEG using the scripts from bambuser http://bambuser.com/opensource.
I then moved the resulting directory into the windows under my project's jni folder and referred the libs from my Android.mk
FFMPEG_DIR := ffmpeg
ifeq ($(TARGET_ARCH_ABI), armeabi)
FFMPEG_DIR := $(FFMPEG_DIR)/armeabi
else
ifeq ($(TARGET_ARCH_ABI), armeabi-v7a)
FFMPEG_DIR := $(FFMPEG_DIR)/armeabi-v7a
endif
endif

You can use this as build_android.sh i tested it and it worked with me
#!/bin/bash
NDK=D:/android/ndk/android-ndk-r10d
SYSROOT=$NDK/platforms/android-8/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/windows
function build_one
{

make clean

}

build_one
you need also to run this commands :
dos2unix build_android.sh
chmod +x build_android.sh
./build_android.sh
