  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP 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" (...)

  • compile FFmpeg → Android { error : crtend_android.o : No such file or directory }

    22 mars 2013, par Jason Tsai

    I'm trying to complie FFmpeg on Android 4.0 (SAMSUNG GT-3113), and I meet an error when I try to get config.h and config.mak files.
    I'm using android-ndk-r8d and cygwin.

    The config.sh file which I created is followed :

    #!/bin/bash

${ndk}/platforms/${PLATFORM}/arch-arm/usr/lib/crtend_android.o -lc -lm -ldl "

    After I run the config.sh with cygwin,it shows
    http://cygwin.com/cygwin-ug-net/using.html#using-pathnames/home/jason_tsai/android-ndk-r8d/toolchains/arm-linux-androideabi-4.7/prebuilt/windows/bin/arm-linux-androideabi-gcc is unable to create an executable file.C compiler test failed.

    I looked the logfile and it said
    arm-linux-androideabi-gcc.exe : error : /home/jason_tsai/android-ndk-r8d/platforms/android-14/arch-arm/usr/lib/crtend_android.o : No such file or directory
    C compiler test failed.

    I'm really very confusing.
    Any help will be appreciated. Thanks !!

  • Libav linking error : undefined references

    22 février 2017, par Fedech

    Here’s my problem :

    • I built ffmpeg from source (version 1.2), the libav* libraries are in /usr/local/lib and they’re static
    • I’m compiling a ns3 (www.nsnam.org) module, so my only control over the linker is through the env variable LINKFLAGS
    • In the source the headers are in a "extern C" block, so it’s not the usual g++ name mangling
    • I set LINKFLAGS="-I/usr/local/include/libavformat -I/usr/local/include/libavcodec -I/usr/local/include/libavutil -L/usr/local/lib -lavformat -lavcodec -lavutil", and the linker can’t seem to find any of the libav* functions I call (I get a lot of "undefined reference" and then "collect2 : error : ld returned status 1"

    Can anyone help me ? Thanks...

    edit : here are a few of the undefined reference messages :

        ./libns3.14.1-qoe-monitor-debug.so: undefined reference to `av_guess_format'
    
    ./libns3.14.1-qoe-monitor-debug.so: undefined reference to `av_read_frame'

    edit2 : here is the message I get after "build failed" :

  • CANNOT LINK EXECUTABLE error with required libs loaded. How to link them properly ? [duplicate]

    4 avril 2013, par dentex

    This question already has an answer here :

    edit : I'm aware of the possible duplicate, but the answer it's not directly applicable. I'm using ProcessBuilder and not Runtime.getRuntime().exec :

    public int execProcess(List<string> cmds, ShellUtils.ShellCallback sc) {    
    
    StringBuilder cmdlog = new StringBuilder();
    
    for (String cmd : cmds) {
    
         cmdlog.append(&#39; &#39;);
    
    }
    
    Utils.logger("v", cmdlog.toString(), DEBUG_TAG);
    

    
    ProcessBuilder pb = new ProcessBuilder();
    
    pb.directory(mBinFileDir);
    
    pb.command(cmds);
    

    
    Process process = null;
    
    int exitVal = 1; // Default error
    
    try {
    
        process = pb.start();
    

    
        StreamGobbler errorGobbler = new
    
        StreamGobbler(process.getErrorStream(), "ERROR", sc);
    

    
        StreamGobbler outputGobbler = new
    
        StreamGobbler(process.getInputStream(), "OUTPUT", sc);
    

    
        errorGobbler.start();
    
        outputGobbler.start();
    

    
        exitVal = process.waitFor();
    

    
        sc.processComplete(exitVal);
    

    
     } catch (Exception e) {
    
         Log.e(DEBUG_TAG, "Error executing ffmpeg command!", e);
    
     } finally {
    
         if (process != null) {
    
             Utils.logger("w", "destroyng process", DEBUG_TAG);
    
             process.destroy();
    
         }
    
    }

    I have two versions on FFmpeg compiled for android : with and without liblame enabled.

    When I load in /data/data/&lt;>/app_bin/ the FFmpeg binary compiled with NO lame support, it extracts audio from video without an issue. But when I use the one with lame support enabled, I get the error below into the log.

    Required libs, also compiled for android, are correctly loaded when shipped into the libs project folder with System.loadLibrary("lame").

    I was wondering if there is something else to do in order to properly make the FFmpeg binary find the libs.
    Those are the same libs given to the NDK to build the FFmpeg binary.

    D/dalvikvm(13741): Trying to load lib /data/app-lib/&lt;>/liblame.so 0x40ffed08
    
D/dalvikvm(13741): Added shared lib /data/app-lib/&lt;>/liblame.so 0x40ffed08
    
D/dalvikvm(13741): No JNI_OnLoad found in /data/app-lib/&lt;>/liblame.so 0x40ffed08, skipping init

V/FfmpegController(13741): /data/data/&lt;>/app_bin/ffmpeg -y -i /storage/sdcard0/Download/video.webm -vn -acodec copy /storage/sdcard0/Download/audio.ogg

D/DownloadsService(13741): soinfo_link_image(linker.cpp:1673): could not load library "liblame.so" needed by "/data/data/&lt;>/app_bin/ffmpeg"; caused by load_library(linker.cpp:771): library "liblame.so" not foundCANNOT LINK EXECUTABLE
    
>>>>>> ---------- &lt;&lt;&lt;&lt;&lt;&lt;
    
I/DownloadsService(13741): FFmpeg process exit value: 255

    I'm not attaching code because it's fairly straightforward :

    • download the FFmpeg binary (it's not shipped with the app) ;
    • copy the binary from the download folder to /data/data/&lt;>/app_bin/ ;
    • chmod 755 ;
    • execute from there and read the output.

    Please comment if something else is required.
