  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • 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.

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Converting DVD image with subtitles to MKV using avconv

    16 janvier 2016, par Carlos Eugenio Thompson Pinzón

    This is the procedure I know to convert a DVD image to another videoformat (v.g. MP4) :

    1. concatenate the VTS_01_n.VOB files inside VIDEO_TS folder (for n >= 0) into a single VOB file.
    2. use avconv or ffmpeg in order to convert that VOB into another format.

    So far so good, however now I want to convert the DVD image with the subtitles. As far as I know the MKV format supports subtitles, so it seems an obvious choice. Alternatively I might use any other format with hard subtitles (subtitles as part of the video image).

    However, the subtitle encoding in the DVD image is dvdsub and I get the following error

    Only SUBTITLE_ASS type supported.
    
Subtitle encoding failed

    However, when running avconv -codecs I get :

    ...
    
 DES    dvdsub          DVD subtitles
    
...

    And the -c:s copy switch, while it prevents the command to fail, it does not seem to produce a subtitle that the player can understand.

    So, how can I create ass subtitles from dvdsub using avconv ?

    My VOB file has eight subtitle channels and two audio channels. The Ubuntu video app does not show any subtitles, and only the first audio channel seems to be working, do the DVD image might be broken.

    Another file, for a double-layer DVD, displays the Subtitle encoding error, however when using the -c:s copy switch it further displays :

    Application provided invalid, non monotonically increasing dts to muxer in stream 2: 49 >= 49
    
av_interleaved_write_frame(): Invalid argument

    Thank you in advance for any ideas on how to solve these problems.

    (I am using Ubuntu where ffmpeg is an alias for avconv. I know it is possible to install the real ffmpeg but so far I have not done so.)

    sendBook and saveBook should return the filename

    Rev. 2.13 - 2013-09-26
    
* Fixed : sendBook and saveBook returned boolean TRUE/FALSE depending on
    
if the sending was successful. The sanitized/used filename was never
    
exposed. The methods now return the filename used for sending, or FALSE
    
if it failed.
    
* Change : sanitizeFileName is now a public function.

  • How to grab voice and video in ffmpeg/mplayer/mencoder ? [closed]

    My target is to grab voice and video via webcamera.
    There are three ways to do :

    mplayer tv:// -tv driver=v4l2:input=0:width=640:height=480:fps=25 -vo x11  

    I can see the video when the command run, how can I save the output into a file and grab the voice ?
