  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
    Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

  • Android ffmpeg release :invalid address or address of corrupt block passed to dlfree

    11 janvier 2018, par jcguo

    guys.I’m new to Android JNI development as well as ffmpeg libs.

    With some struggles, I have managed to decode the real time H264 data, but meeting error when release the ffmpeg decoder :

    12-11 19:54:36.428  27959-27959/com.example.firmament.dji A/libc﹕ invalid address or address of corrupt block 0x6fa13868 passed to dlfree
    
12-11 19:54:36.430  27959-27959/com.example.firmament.dji A/libc﹕ Fatal signal 11 (SIGSEGV) at 0xdeadbaad (code=1), thread 27959 (e.firmament.dji)

    Some questions in stackoverflow mentioned that this error related to wrongly free some memory which was protected(same with Segment Fault).

    I checked the C JNI code for times and could not fix the bug, here is my code(release part) :

    jint Java_com_example_firmament_dji_XKZH264_release(JNIEnv *env, jobject obj)
    
{
    
    if (pFrame != NULL) {
    
        av_free(pFrame);
    
        pFrame = NULL;
    
    }
    

    
    if (pCodecContext != NULL) {
    
        avcodec_close(pCodecContext);
    
        av_free(pCodecContext);
    
        pCodecContext = NULL;
    
    }
    

    
    if (pParserContext != NULL) {
    
        av_parser_close(pParserContext);
    
        av_free(pParserContext);
    
        pParserContext = NULL;
    
    }
    

    
    DeleteYUVTab();
    

    
    return 1;
    
}
    

    
void DeleteYUVTab()
    
{
    
    if (colortab != NULL) {
    
        av_free(colortab);
    
        colortab = NULL;
    
    }
    

    
    if (rgb_2_pix != NULL) {
    
        av_free(rgb_2_pix);
    
        colortab = NULL;
    
    }
