MediaSPIP 0.1 Beta version

25 avril 2011, par kent1

MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
The zip file provided here only contains the sources of MediaSPIP in its standalone version.
To get a working installation, you must manually install all-software dependencies on the server.
If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)
Multilang : améliorer l’interface pour les blocs multilingues

18 février 2011, par kent1

Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.
L’agrémenter visuellement

10 avril 2011

MediaSPIP est basé sur un système de thèmes et de squelettes. Les squelettes définissent le placement des informations dans la page, définissant un usage spécifique de la plateforme, et les thèmes l’habillage graphique général.
Chacun peut proposer un nouveau thème graphique ou un squelette et le mettre à disposition de la communauté.

fps porblem when saving video in mp4 container

27 novembre 2012, par theateist

When I decode frames from avi file and then decode them in x264 and save to mp4 file, the fps of the output file is always 12,800. Therefore the file is played very fast. But, when I save the encoded in h264 frames in avi format and not mp4, so the fps is as I wanted - 25.

What could be the problem ?
This is very urgent to me. I'm stuck with this and cannot continue with my project !

Here the code I wrote in VS2010 :

#include "stdafx.h"

#include "inttypes.h"

undefined reference to ffmpeg functions in native code using Android Studio 2.2

12 octobre 2016, par Krzysztof Kansy

I have a problem with using ffmpeg in Android Studio 2.2 using NDK 13 and new Cmake building system. FFmpeg version is 3.1.4.
The system I’m working on is Linux Mint 18 64-bit.
At the build time I’m getting undefined reference error each time I use ffpeg functions.

My MainActivity.java :

public class MainActivity extends AppCompatActivity {



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);



    // Example of a call to a native method

    TextView tv = (TextView) findViewById(R.id.sample_text);

    tv.setText(stringFromJNI());

    }



    /**

     * A native method that is implemented by the 'native-lib' native library,

     * which is packaged with this application.

     */

    public native String stringFromJNI();



    // Used to load the 'native-lib' library on application startup.

    static {

        System.loadLibrary("native-lib");

    }

}

My native class (undefined reference is pointing to av_init_packet(&avPacket)) :

#include 

#include <string>

#include <android></android>log.h>

#include <libavcodec></libavcodec>avcodec.h>





extern "C"

jstring

Java_com_example_tito_jnitest_MainActivity_stringFromJNI(

        JNIEnv* env,

        jobject /* this */) {



    std::string hello = "Hello from C++";



    __android_log_print(ANDROID_LOG_INFO, "JNItest", "Hello from JNI!");



    AVPacket avPacket;

    av_init_packet(&amp;avPacket);



    return env->NewStringUTF(hello.c_str());

}

</string>

One thing I noticed that could indicate that something is wrong with ffmpeg build is warning WARNING: /home/tito/Android/Sdk/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-pkg-config not found, library detection may fail. during building. I’m not sure if this may be cause of problems.

I was trying to build for all of the ABIs, but for now I decided to focus on making just armeabi working. I’m having exact same failure after using e.g. arm64-v8a.

Finally, here is the gradle console’s content with error :
