    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) (...)

  • configure : Simplify cygwin/mingw/msys code

    3 novembre 2015, par Henrik Gramner
    configure : Simplify cygwin/mingw/msys code

    Avoids some code duplication.
    

    Also drop the -mno-cygwin check since that option was removed back in 2008.

  • Where to get an up to date php_ffmpeg.dll

    25 avril 2015, par Heidi

    I have Windows 2008 R2 64 bit.
    I have installed ResourceSpace 7.1.6513 which requires PHP & FFMPEG. This is not a ResourceSpace question.

    I have installed PHP 5.4.40 VC9 x86 non thread safe (as advised by ResourceSpace wiki & GG).
    I have installed FFMPEG version N-71664-gcd69c0e (64 bit static)

    Now it seems that FFMPEG and PHP need to have a php_ffmpeg.dll to work in Windows.
    Is that true ?

    If so, where do I get one that will work with my FFMPEG & PHP ? I have looked here and followed old threads, and have found random php_ffmpeg.dlls but I cannot confirm that they are compatible.
    The file taht I found, I have put it c :\php\ext and updated php.ini with extension=php_ffmpeg.dll

  • FFmpeg - downmixing FLAC 6.1 to AAC 5.1

    7 juillet 2014, par Martijn

    I can’t seem to figure out how to do this. I’ve been staring at these commands :
    https://trac.ffmpeg.org/wiki/AudioChannelManipulation

    But to no avail. It’s a tad above my level, sadly. Here’s the ffmpeg -i output for the video in question :

    As you can see, one of the streams is a FLAC 6.1 stream. I wanted to convert that to AAC, and I know how to do that, basically like this :

    ffmpeg -i "input.mkv" -codec:v copy -codec:a aac -strict -2 -b:a 320k -f matroska "output.mkv"

    But apparently AAC doesn’t support 6.1 audio :

    ...
    
[aac @ 03b26860] Unsupported number of channels: 7
    
Output #0, matroska, to 'd:\Movies\[Coalgirls]_Spirited_Away_(1920x1038_Blu-ray_FLAC)_[92372194].aac.mkv':
    
    Stream #0:0(jpn): Video: h264, yuv420p10le, 1920x1038 [SAR 1:1 DAR 320:173], q=2-31, 23.98 fps, 90k tbn, 1k tbc (default)
    
    Stream #0:1(jpn): Audio: aac, 0 channels, 128 kb/s (default)
    
    Metadata:
    
      encoder         : Lavc55.67.100 aac
    
    Stream #0:2(eng): Subtitle: ssa, 128 kb/s (default)
    
    Metadata:
    
      encoder         : Lavc55.67.100 ssa
    
Stream mapping:
    
  Stream #0:0 -> #0:0 (copy)
    
  Stream #0:1 -> #0:1 (flac (native) -> aac (aac))
    
  Stream #0:9 -> #0:2 (ssa (native) -> ssa (native))
    
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    That’s fine, so I wanted to downmix it to 5.1 and encode as AAC. But I can’t seem to work out how to. Any advice ?
