MediaSPIP en mode privé (Intranet)
17 septembre 2013, parÀ partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...) -

How to link .so library on Android
9 juin 2014, par SayakiI’m trying to use FFMpeg with Android. First of all I have tryed to build FFMpeg on my Mac but I cant do that. I checked many solution on Internet but none working. Becouse of that I try to build FFMpeg on Ubuntu 12.04. I try a lot of solutions bu finally I found this example and I succeed build it. Then I get headers files and .so files. Then I copy all of them on my mac and try to use it in my project. I copy this files to my project. Now my project tree looks like this :
Here is my Android.mk file :
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := avformat
LOCAL_SRC_FILES := libavformat.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include/libavformat
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := ndksetup
LOCAL_SRC_FILES := native.c
LOCAL_LDLIBS := -llog
LOCAL_C_INCLUDES := $(LOCAL_PATH)/include
include $(BUILD_SHARED_LIBRARY)Here is my Application.mk file :
APP_MODULES := ndksetup
APP_PLATFORM := android-8
LOCAL_SRC_FILES := $(TARGET_ARCH_ABI)/libavformat.soHere is my natice.c file :
#include
#include
#include <android></android>log.h>
#include "include/libavcodec/avcodec.h"
#include "include/libavformat/avformat.h"
#define DEBUG_TAG "NDKSetupActivity"
void Java_com_example_ndksetup_MainActivity_printLog(JNIEnv *env, jobject this,
jstring logString) {
av_register_all();
jboolean isCopy;
const char * szLogString = (*env)->GetStringUTFChars(env, logString,
&isCopy);
__android_log_print(ANDROID_LOG_DEBUG, DEBUG_TAG, "NDK: %s", szLogString);
(*env)->ReleaseStringUTFChars(env, logString, szLogString);
}
jint Java_com_example_ndksetup_MainActivity_fibonacci(JNIEnv * env,
jobject this, jint value) {
if (value <= 1)
return value;
return Java_com_example_ndksetup_MainActivity_fibonacci(env, this,
value - 1)
+ Java_com_example_ndksetup_MainActivity_fibonacci(env, this,
value - 2);
}I get error
[armeabi] SharedLibrary : libndksetup.so
/Applications/adt-bundle-mac-x86_64-20140321/sdk/ndk/toolchains/arm-linux-androideabi-4.6/prebuilt/darwin-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/ld: /Users/michal/Desktop/NDKSetup/obj/local/armeabi/objs/ndksetup/native.o: in function Java_com_example_ndksetup_MainActivity_printLog:/Users/michal/Desktop/NDKSetup/jni/native.c:11: error: undefined reference to 'av_register_all'
collect2: ld returned 1 exit status
make: *** [/Users/michal/Desktop/NDKSetup/obj/local/armeabi/libndksetup.so] Error 1And I really dont know how to deal with it. Can you tell me what Im dooing wrong and how can I fix it ? Or maybe there is another way to use .so library in Android

FFMPEG not creating thumbnails and converting videos
10 juin 2014, par KartikAThis is what I coded after reading many blogs and about FFMPEG
$ffmpeg = "C:\\FFMPEG\\bin\\ffmpeg";
$video_file_path = $_FILES["file"]["name"];
$converted_video_path = "converted_videos/" . $video_file_path;
$image = $name .".jpg";
$imagepath="thumbnail/" . $image;
echo "<br />";
echo $video_file_path; echo "<br />";echo "<br />";
echo $converted_video_path; echo "<br />";echo "<br />";
echo $image; echo "<br />";echo "<br />";
echo $imagepath;
$size = "120x90";
$getFromSecond = 6;
$cmd_thumbnail_create = ("$ffmpeg -i C:\\xampp\\htdocs\\Media Barron\\assets\\uploaded_videos\\$video_file_path -an -ss $getFromSecond -s $size C:\\xampp\\htdocs\\Media Barron\\assets\\thumbnail\\$image");
$cmd_video_conversion = exec("$ffmpeg -i $video_file_path -qscale 4 -vcodec libx264 -f mp4 $converted_video_path.mp4");
shell_exec($cmd_thumbnail_create);
shell_exec($cmd_video_conversion);PS : I had double quotes on the addresses earlier and also tired "\uploaded_videos\video_file_path", "uploaded_videos\video_file_path", Single quotes, "\C :\xampp\htdocs\Media Barron\assets\uploaded_videos\$video_file_path\"
This is the New script I have tried recently
<?php
$ffmpeg = "C:\\FFMPEG\\bin\\ffmpeg";
$video_file_path = $_FILES["file"]["name"];
$ffmpegVideoLocation = "C:\\xampp\\htdoc\\Media Barron\\uploaded_videos\\".$video_file_path;
$converted_video_path = "C:\\xampp\\htdoc\\Media Barron\\converted_videos\\" . $video_file_path;
$image = $name .".jpg";
$imagepath="thumbnail\\" . $image;
echo "<br />";
echo $video_file_path; echo "<br />";echo "<br />";
echo $ffmpegVideoLocation; echo "<br />";echo "<br />";
echo $converted_video_path; echo "<br />";echo "<br />";
echo $image; echo "<br />";echo "<br />";
echo $imagepath;
$size = "120x90";
$getFromSecond = 6;
$cmd_thumbnail_create = ("$ffmpeg -i $ffmpegVideoLocation -an -ss $getFromSecond -s $size $converted_video_path.jpg");
$cmd_video_conversion = exec("$ffmpeg -i $ffmpegVideoLocation -qscale 4 -vcodec libx264 -f mp4 $converted_video_path.mp4");
shell_exec($cmd_video_conversion);
shell_exec($cmd_thumbnail_create); -
FFMPEG conversion error from MKV to MP4 using libfdk_aac codec
23 août 2014, par Charlie BrownThe purpose of doing this is because my "Smart" samsung TV doesn’t play MKV files.
This thread mentions that there is no need for video conversion, just changing the container might suffice. After reading multiple threads on how to change the container of MKV to MP4, I downloaded and compiled the FFMPEG with libfdk_aac support from here. I tried converting a sample MKV file using this command :
ffmpeg -i "C:\VideoTest\Sample1.mkv" -c:v copy -c:a libfdk_aac -b:a 384k "C:\VideoTest\Sample2.mp4"
but getting the following errors (copied from command prompt) :
