  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • test_streams : Use fopen instead of flac_fopen

    test_streams : Use fopen instead of flac_fopen

    test_streams doesn’t create/open files with non-ascii filenames,
    
so there’s no need in unicode support.

    avformat/rtpdec_jpeg : fix low contrast image on low quality setting

    Original mail and my own followup on ffmpeg-user earlier today :
    

    I have a device sending out a MJPEG/RTP stream on a low quality setting.
    
Decoding and displaying the video with libavformat results in a washed
    
out, low contrast, greyish image. Playing the same stream with VLC results
    
in proper color representation.
    

    Screenshots for comparison :

    A pcap capture of a few seconds of video and SDP file for playing the
    
stream are available at

    I believe the problem might be in the calculation of the quantization
    
tables in the function create_default_qtables(), the attached patch
    
solves the issue for me.
    

    The problem is that the argument ’q’ is of the type uint8_t. According to the
    
JPEG standard, if 1 <= q <= 50, the scale factor ’S’ should be 5000 / Q.
    
Because the create_default_qtables() reuses the variable ’q’ to store the
    
result of this calculation, for small values of q < 19, q wil subsequently
    
overflow and give wrong results in the calculated quantization tables. The
    
patch below uses a new variable ’S’ (same name as in RFC2435) with the proper
    
range to store the result of the division.

  • src/ : Remove un-needed MSVC6 workaround.

    4 juillet 2014, par Erik de Castro Lopo
    src/ : Remove un-needed MSVC6 workaround.

    MSVC6 was not able to cast from a uint64_t to a double and this
    
commit removes some #ifdef hackery designed to work around this
    
problem.
