  • C# Using ffmpeg with binary data

    27 juillet 2015, par user3763117

    I have the need to make several posters from a movie, however I bounched in several problems.

    I have been searching yesterday whole day how this works and what might be the best solution to do this in my C# project, currently as this far.

    AForge.Video.FFMPEG.VideoFileWriter writer = new VideoFileWriter();
    
writer.Open("en.code-bude_test_video.avi", width, height, 25, VideoCodec.MPEG4, 1000000);

    Following the documentation this should work with a local avi file, however I have my movie in binary and have no understanding how to use this stream to let the ffmpeg writer read this

    data is contained like this :

    Byte[] bytes = Convert.IsDBNull(s[col]) ? null : (Byte[])s[col];

    Anybody idea how to do this ?

  • Discard data stream from container using ffmpeg

    10 décembre 2020, par A.Be

    I am trying to get rid of a data (subtitle) stream within a Mp4 container, using ffmpeg.

    



    Here's the screenshot from ffprobe :

    I tried :

    



     ffmpeg -i test.m4v -acodec copy -vcodec copy -sn nodata.mp4


    



    Data track still there, just moved from stream 0 to stream 2

    



    I tried also :

    



     ffmpeg -i test.m4v -acodec copy -vcodec copy -map 0:1 -map 0:2 no2.mp4


    



    Same result, track still there, just jumped to stream 0:2 no luck.

    



    Any hint ?
Thanks in advance

    


  • Anomalie #2748 : Dénoncées les erreurs dans les boucles DATA pour yql

    6 juin 2012, par marcimat -

    Fonction inc_yql_to_array_dist() dans ecrire/iterateur/data. T’a pu qu’à... Après, idéalement, il faudrait faire remonter les erreurs pour en faire une erreur de squelette, ça serait plus propre.
