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

    22 mai 2015, 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;
    
    }
    
}
