  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • Recorded by FFMpeg Video doesn't show the statistics in details

    28 novembre 2019, par okandnmz

    I use the FFMpeg to record the video I received as input with "Pipe". Although the recording process was successful after recording, no statistics, details are given in the details tab (Right click to recorded video -> properties -> details tab) (Windows 10)

    My FFMpeg commands something like that :

    ffmpeg -vsync 1 -i %PIPE% ....

    For this problem, I’ve already tried the following commands :

    -metadata ....
    -vstats ......

    Probably i misunderstood that commands so in the result both of them is not working. Should i specify that values (title, fps, bitrate...) in somewhere and for that aim is there any commands ?
    (the recorded video source is not the existing file, its live stream)

  • ffmpeg libfdk-aac open coder error and show The encoder timebase is not set

    28 octobre 2019, par RodSteward

    I try to encode some pcm data,and I compile ffmpeg for myself with libfdk-aac,but When I use a aac encoder,It shows timebase is not set,but aac data seems not need a timebase,and even I set the timebase,it shows the same error again

    here is the Initializationcode :

       AVCodec *pCodec;
       AVCodecContext *pCodecCtx = NULL;
       int i, ret, got_output;
       FILE *fp_in;
       FILE *fp_out;

       AVFrame *pFrame;
       uint8_t* frame_buf;
       int size = 0;

       AVPacket pkt;
       int y_size;
       int framecnt = 0;

       char filename_in[] = "tdjm.pcm";

       AVCodecID codec_id = AV_CODEC_ID_AAC;
       char filename_out[] = "tdjm.aac";

       int framenum = 1000;

       avcodec_register_all();

       pCodec = avcodec_find_encoder_by_name("libfdk_aac");
       if (!pCodec) {
           printf("Codec not found\n");
           return -1;
       }
       pCodecCtx = avcodec_alloc_context3(pCodec);
       if (!pCodecCtx) {
           printf("Could not allocate video codec context\n");
           return -1;
       }

       //pCodecCtx->codec_id = codec_id;
       pCodecCtx->codec_type = AVMEDIA_TYPE_AUDIO;
       pCodecCtx->sample_fmt = AV_SAMPLE_FMT_S16;
       pCodecCtx->sample_rate = 44100;
       pCodecCtx->channel_layout = AV_CH_LAYOUT_STEREO;
       pCodecCtx->channels = av_get_channel_layout_nb_channels(pCodecCtx->channel_layout);
       pCodecCtx->bit_rate = 64000;
       pCodecCtx->time_base = AVRational{1,10};

       if (avcodec_open2(pCodecCtx, pCodec, NULL) < 0) {
           printf("Could not open codec\n");

  • FFMPEG, the penultimate image from the .txt file doesn't show in the video

    25 octobre 2019, par ArmKh

    I’m trying to create a video from the images using ffmeg. Actually, the creating of the video works but there is a small problem. I have a text file with the names of the images (paths) which I’m using in the video. The file looks like this

    file 'image1.jpg'
    file 'image2.jpg'
    file 'image3.jpg'
    file 'image4.jpg'
    file 'image5.jpg'

    And the ffmeg command is following

    ffmpeg -y -r 1/5 -f concat -safe 0 -i imagenames.txt -i some_audio.mp3 -c:v libx264 -vf fps=30 -pix_fmt yuv420p -t 30 output.mp4

    This video should keep the frame on every image for 5 seconds. But the problem is the penultimate image ( image4 in this case ) is not being shown in the video. So, it keeps on image3 10 seconds and moves to image5

    So, the video in seconds looks like this

    [image1] -> [image2] -> [image3] -> [image4] -> [image5]
      5sec        5sec       10sec        0sec        5sec

    And the problem is not with the image4 exactly. In case of swapping image3 and image4, the video will skip image3

    [image1] -> [image2] -> [image4] -> [image3] -> [image5]
      5sec        5sec       10sec        0sec        5sec

    Hope you’ll have any suggestions to fix this issue
