Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

NoMethodFoundException when trying to load native methods from jar file
20 février 2018, par Anuran BarmanI am trying to load ffmpeg methods in android. My requirement is that I dont want to pack the .so files within the apk.Only if the user wants then only I will download the jar file and load the ffmpeg native methods.After searching I think that loading .so files at run time is not possible.So what I did that I made the so file and created a different android application with only one class FFMPEG.java whose only duty is to call the native methods from ffmpeg library.so I made the jar file and loaded that into my main application with ClassLoader. Constructor is getting called so it means class is loaded but methods are not getting loaded though they are declared public in the jar file. I am trying to stream RTSP video with FFMPEG.Below are my jar file and main application codes.
public class FFMPEG {
public FFMPEG(){
Log.d(FFMPEG.class.getSimpleName(),"constructor called");
}
public static native int naInit(String pFileName);
public static native int[] naGetVideoRes();
public static native void naSetSurface(Surface pSurface);
public static native int naSetup(int pWidth, int pHeight);

try {
System.loadLibrary("avutil");
System.loadLibrary("avcodec");
System.loadLibrary("avformat");
