    12 juillet 2016, par Yoohoo

    Hi，I am currently doing a real time video encoding c program using ffmpeg, initially I encountered a lot of "undefined reference" error, after I set the linker in build options, some error got disappeared, but still some error remains.

    Here are my screen shot of the CodeBlock linker setting.

ffmpeg_build/lib/libavcodec.a

    Totally 10 libs.

    My Questions :

    1. Are these errors caused by lacking libs or libs not linked.
    2. What libs I missing or what libs should I add to linker.

  • Error while building ParaView on ubuntu

    21 février 2014, par user3337492

    I´ve got school project that I have to build ParaView and work with it in parallel.

    I am using this guide : http://paraview.org/Wiki/ParaView:Build_And_Install

    I´ve installed all the required packages and now it is time to "Configure ParaView With CMake".

    When I do this recomended code

    mkdir $HOME/projects/ParaView-bin

    cd $HOME/projects/ParaView-bin

    ccmake $HOME/projects/ParaView3

    the terminal shows this :

    CMake Error : The source "/home/kulis/projects/ParaView3/CMakeLists.txt" does
    not match the source "/home/kulis/projects/ParaView/CMakeLists.txt" used to
    generate cache. Re-run cmake with a different source directory.

    so instead of ParaView3 I use ParaView in code : ccmake $HOME/projects/ParaView

    then its possible to set all the variables and compile. But there comes the real problem. When i want to compile it, the terminal shows this error message :

    ERROR ADD_PARAVIEW_VIEW_MODULE called without VIEW_TYPE or VIEW_XML_GROUP

    CMake Error : The following variables are used in this project, but they are set to NOTFOUND.
    Please set them or make sure they are set and tested correctly in the CMake files :
    /home/kulis/projects/ParaView/VTK/IO/FFMPEG/FFMPEG_INCLUDE_DIR
    used as include directory in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avcodec_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avformat_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avutil_LIBRARY (ADVANCED)

    FFMPEG_swscale_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG

    And I do not really know what to do with it.

    I would very much appreciate your help. Thanks

  • Error during decoding (-1094995529) Invalid data found when processing input

    8 mai 2018, par Harshil Makwana

    I wants Hardware Acceleration using dxva2. In my code Software decoding works fine but with hardware acceleration avcodec_send_packet return negative value(-1094995529). Help me to fix this ?

    Initialization of dxva2 hardware :

    enum AVHWDeviceType type = av_hwdevice_find_type_by_name("dxva2");
    

    
if (type == AV_HWDEVICE_TYPE_NONE) {
    
fprintf(fp, "Hardware Device type is not supported.\n");
    
return -1;
    
}
    

    
 for (int i = 0;; i++) {
    

    
        const AVCodecHWConfig *config = avcodec_get_hw_config(sChannelInfo[chNum].codec, i);
    

    
        if (!config) {
    
            fprintf(fp, "Failed to get Hardware Configuartion\n");
    
            return -1;
    
        }
    

    
        if (config->methods & AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX &&
    
            config->device_type == type) {
    
            hw_pix_fmt = config->pix_fmt;
    
            fprintf(fp, "config->pix_fmt  %d\n", (int)hw_pix_fmt);
    
            break;
    
        }
    

    
    }
    

    
    sChannelInfo[chNum].pCodecContext->pix_fmt = AV_PIX_FMT_DXVA2_VLD;
    
    sChannelInfo[chNum].pCodecContext->get_format = get_hw_format;
    
    av_opt_set_int(sChannelInfo[chNum].pCodecContext, "refcounted_frames", 1, 0);
    

    
    if (hw_decoder_init(sChannelInfo[chNum].pCodecContext, type) < 0)
    
    {
    
        fprintf(fp, "hardware decoder initilisation Failed\n");
    
        return -1;
    
    }

    Decode :

    int ret = avcodec_send_packet(sChannelInfo[chNum].pCodecContext, &pkt);
    
if (ret < 0) {
    
    char buffer[64];
    
    av_make_error_string(buffer, 64, ret);
    
    fprintf(fp, "Error during decoding %d %s\n",ret,buffer);
    
    return ret;
    
    }

    Why avcodec_send_packet API return -1094995529 value ?
    Is there anything missing in dxva2 initialization ?
