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.
ANNEXE : Les plugins utilisés spécifiquement pour la ferme

5 mars 2010, par kent1

Le site central/maître de la ferme a besoin d’utiliser plusieurs plugins supplémentaires vis à vis des canaux pour son bon fonctionnement. le plugin Gestion de la mutualisation ; le plugin inscription3 pour gérer les inscriptions et les demandes de création d’instance de mutualisation dès l’inscription des utilisateurs ; le plugin verifier qui fournit une API de vérification des champs (utilisé par inscription3) ; le plugin champs extras v2 nécessité par inscription3 (...)

fic : set pict_type/key_frame after (instead of during) slice decoding.

28 mars 2017, par Ronald S. Bultje

fic : set pict_type/key_frame after (instead of during) slice decoding.

This fixes a race condition that was already documented in the source
code, and is also reported by tsan in fate-fic-avi.

hevc : initialize no_rasl_output_flag in hevc_frame_start().

27 mars 2017, par Ronald S. Bultje

hevc : initialize no_rasl_output_flag in hevc_frame_start().

This prevents a race condition in files with multiple slices per frame.

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>

Build process of ffmpeg seemed to be successful. Here’s my build script :

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 :
