    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) (...)

  • audio extracted from flv file via ffmpeg is of shorter duration than the actual flv video [closed]

    11 janvier 2013, par user1961143

    I have extracted audio from flv file via ffmpeg using this command :-

    ffmpeg -i 164_29.flv v19.mp3

    The flv videos duration is 3 minutes but the audio is of 2 mins 20 seconds only. On searching i found that the silent pieces of audio are removed when generating audio from ffmpeg. But i need the audio file to be of exactly same duration as flv video as later i need to put this audio in the flv video itself. Please help as this is urgent for our project. I am running the FFMpeg via .net windows service, so in case you know any other tool which can extract the audio of same duration as video and can be run via .net, it would be useful too.

    If you see the duration of video is of 3:04 but audio extracted from it is of 2:25 only.
    Actually i am using ffmpeg overlay to show two videos side by side in our debate project for the client. Now ffmpeg takes audio from first video by default. But we want the audio from both videos together as a debate going on. Hence I thought of a solution to extract audio from both videos and merge them and than apply them to the overlayed video. This will all work perfectly only if I get the complete audio from the video file i.e. of equal duration.
    For more information i am writing here the overlay command we are using :-

     **ffmpeg -i 164_29.flv  -vf "[in] scale=359:320, pad=2*iw+6:ih
    
  [left];    movie=164_30.flv, scale=359:320 [right]; [left][right] 
    
  overlay=365:0  [out]" -b:v 3600k -y a1.flv**
    

    
 **This is the console output of this overlay command:-**

    C :\Users\ritika.thakur>ffmpeg -i 164_29.flv -vf "[in] scale=359:320, pad=2*iw+6
    :ih [left] ; movie=164_30.flv, scale=359:320 [right] ; [left][right] overlay=365:0
    [out]" -b:v 3600k -y a1.flv

    Everything is working fine except that we want audio from both videos playing together in final overlayed file. I would be highly grateful if you can help in this and let me know if its possible to do via ffmpeg or not.

  • How to decompress a compressed type audio file using ffmpeg ?

    28 janvier 2017, par iPhoneDev

    I need to decompress an audio file through code using ffmpeg.

  • CLSID for x264 DirectShow filter

    12 mai 2012, par meghana

    I have used x264 DirectShow filter from Monogram for decoding h264 avc video , i need to create intrance and add filter to graph in directshow , i checked the CLSID of it from grapthEdit , and that is 'x264' , i guess that to create instance we need the GUID for that filter , i have no clue how can i create filter instance using 'x264' value.

    I am using directshow with vc++
