my project struture like :i create build_android.sh like roman10 as following code :
# ARMv7+Neon (Cortex-A8)
# Customizing:
# 1. Feel free to change ./configure parameters for more features
# 2. To adapt other ARM variants
# set $CPU and $OPTIMIZE_CFLAGS
# call build_one

I built it in Eclipse Everything is ok. but when i ran it in Android it crashed Unfortunately.
I found the errors in Logcat monitor :E/AndroidRuntime(1931) : java.lang.UnsatisfiedLinkError : Couldn’t load avcodec-55 from loader dalvik.system.PathClassLoader[DexPathList [1]] : findLibrary returned null
E/AndroidRuntime(1931) : at java.lang.Runtime.loadLibrary(Runtime.java:358)
In my activity i just call add Library from C preference like :
static {
//System.loadLibrary("avutil-52");
System.loadLibrary("avcodec-55");
System.loadLibrary("avformat-55");
System.loadLibrary("swscale-2");
System.loadLibrary("tutorial02");
}i check in DDMS in app-lib there is no existing Library in there.
The question is : Can i can compile the ffmpeg on windows ?
if ok. how can i config build_android.sh to point to Android $PREBUILTPLATFORM=$NDK/platforms/android-8/arch-arm/
PREBUILT=$NDK/prebuilt/windows-x86_64

--disable-shared \i found that in $NDK/prebuilt/windows-x86_64/bin did not exist arm-linux-androideabi-gcc\
How can i config to be suitable to run on windows ?Thank in advanced

How to install PHP FFMPEG on windows 10 64 Bit
7 septembre 2017, par PlanetHackersI want to install the PHP FFMPEG on my system. My system configuration is :
OS : Windows 10 64 Bit
XAMPP v3.2.2
PHP v7.0.15I found many tutorial but nothing found working. May be due to 64 bit system. I wanted to add a watermark to a video through PHP. That’s why I need the ffmpeg extension. I also tried through Composer but did not get success.
