    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • How to write a code that will call x264 encoder with required settings repeatedly

    11 juin 2018, par MSD Paul

    how to write a sample code that will call the x264 encoder with its required settings repeatedly changing the input frames and also changing the output video where it is writing the encoded frames. As example,

    x264 —crf 23 —tune fastdecode —fps 64 —keyint 1 —min-keyint 1 —no-scenecut —input-res 4096*2048 —bframes 0 -o v1.mp4 C :/vv_folder/vv_%3d.png

    x264 —crf 23 —tune fastdecode —fps 64 —keyint 1 —min-keyint 1 —no-scenecut —input-res 4096*2048 —bframes 0 -o v2.mp4 C :/vv_folder_1/vv_1_%3d.png

    and so on.

    At each time, different sets of frames will be encoded into one mp4 file.

  • How to write uncompressed BMP-images into AVI-container via FFmpeg ?

    4 septembre 2020, par Alexey Matal

    I have a sequence of a 8bpp, gray BMP-files. I need to write them to AVI-container as video-sequence using FFmpeg.

    &#xA;

    I'm use C++ FFmpeg create mp4 file as a stub of my class, with some changes. But change codec to "bmp" and pix_fmt to AV_PIX_FMT_GRAY8 in specified places do not get any result.

    &#xA;

    When I try playing result AVI-file in ffplay, I get this message :

    &#xA;

    &#xA;

    Invalid buffer size, packet size 102454 < expected frame_size 304128

    &#xA;

    &#xA;

    It looks that the problem in pixel-format, but I check all fields in ffmpeg-objects - pixel-format is right..

    &#xA;

    The result I wait is "AVI-container as video-file with uncompressed 8-bit DIB-data".

    &#xA;

    Any solution ? Help pls !
