  • 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) (...)

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • fftools/ffmpeg : report new streams from the input thread

    fftools/ffmpeg : report new streams from the input thread

    This avoids a potential race with the demuxer adding new streams. It is
    
also more efficient, since we no longer do inter-thread transfers of
    
packets that will be just discarded.

  • avcodec : fix time reporting for DFPWM streams

    avcodec : fix time reporting for DFPWM streams

    This adds the exact bits per sample for DFPWM to
    
av_get_exact_bits_per_sample.
    
Previously, the DTS and PTS were set to 0 because the codec never
    
reported them, but adding this allows libavformat to automatically
    
set DTS and PTS from the byte position of the stream.

  • Join two videos with unmatching audio streams in ffmpeg

    1er janvier 2013, par graup

    I already know how to concat multiple files using ffmpeg (e.g. like this).

    However, I have a specific problem. Due to an error while recording, the first video's video stream ends after about 14 minutes, while the audio stream is about 20 minutes long.
    The second video has complete video and audio streams.

    I hope this will make my situation clear :

    File 1:
    
V1: vvvvvvvvvvvvvvv________
    
A1: aaaaaaaaaaaaaaaaaaaaaaa
    

    
File 2:
    
V2: vvvvvvvvvvvv
    
A2: aaaaaaaaaaaa
    

    
Result after converting to MPEG-TS, concatting and encoding to mp4:
    
    vvvvvvvvvvvvvvvvvvvvvvvvvvv________
    
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
    

    
Expected:
    
    vvvvvvvvvvvvvvv________vvvvvvvvvvvv
    
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

    Anyone know how to do that ?
