  • 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) (...)

  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible.

  • Difference between DirectShowSource() and FFmpegSource2() in AviSynth

    29 mars 2024, par MarianD

    For non .avi A/V sources (as .mp3, .mp4, etc.) there are (at least) 2 possibilities for reading those media files in AviSynth (in Windows) :

    



      

    • The built-in media filter DirectShowSource(), using Microsoft's DirectShow media architecture.

      • 


    • The AviSynth Plugin FFmpegSource2() alias FFMS2() using FFmpeg and nothing else.

      • 


    



    What are advantages and disadvantages of them ?
    
Which is more reliable, frame / sample accurate, etc.?

    


  • Why is chrominance lost when i OpenSharedResource from a ffmpeg AVFrame resource ?

    &#xA;

    I copy temp_texture_for_ffmpeg_device to a D3D11_USAGE_STAGING, it's normal, but when i copy temp_texture_for_my_device to a D3D11_USAGE_STAGING, i lost the chrominance data.

    &#xA;

    When i map the texture to cpu via D3D11_USAGE_STAGING :

    &#xA;

    temp_texture_for_ffmpeg_device : RowPitch is 768, DepthPitch is 768 * 720.&#xA;temp_texture_for_my_device : RowPitch is 1024, DepthPitch is 1024 * 480.

    &#xA;

    I think there are some different parameters between the two devices(or device context ?), but I don't know what parameters would cause such a difference in behavior.

    &#xA;

    my_device and my_device_context are created by D3D11On12CreateDevice
