    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) (...)

    libtta 2.3 has a limit of 6 channels, so 16 is substantially above the "official" already

  • ffmpeg empty video with low frame rate

    27 avril 2013, par Marco Gagliardi

    I've just downloaded ffmpeg since it seems to perfectly match my needs (make a video from a set of pictures). I'm currently playing around with some examples just to get started and there's something weird happening that I can't explain.
    I'm trying this command (provided in the official documentation) :

    ffmpeg -f image2 -pattern_type glob -i &#39;foo-*.jpeg&#39; -r 12 -s WxH foo.avi

    on a data set of 10 jpg pictures (of course I changed the pattern with '*.jpg'). The video seems to be encoded correctly but it's simply too fast to be sure about that (anyway it stops on the last frame that corresponds to the last picture). In order to get a longer video i thought to low the frame rate from 12 to 1 (one sec each picture) or 0.5 (2 sec each one) and so on.. no way ! with low rate values even if the video is played the pictures are simply not displayed. The player (VLC in my case) just shows a blank/empty video for a few seconds.

    Am I making something wrong or have I misunderstood the -r parameter ? Is it something related to codecs involved ? Finally.. How can i get each picture displayed for 1 or 2 seconds ?

    Thank you !

  • avformat/dashdec : drop arbitrary DASH manifest size limit

    avformat/dashdec : drop arbitrary DASH manifest size limit

    Currently the utilized AVBPrint API is internally limited to unsigned
    
integers, so if we limit the file size as well as the amount to read
    
to UINT_MAX - 1, we do not require additional limiting to be performed
    
on the values.
    

    This change is based on the fact that initially the 8*1024 value added
    
in 96d70694aea64616c68db8be306c159c73fb3980 was only for the case where
    
the file size was not known. It was not a maximum file size limit.
    

    In 29121188983932f79aef8501652630d322a9974c this was reworked to be
    
a maximum manifest file size limit, while its commit message appears
    
to only note that it added support for larger manifest file sizes.
    

    This should enable various unfortunately large MPEG-DASH manifests,
    
such as Youtube's multi-megabyte live stream archives to load up
    
as well as bring back the original intent of the logic.
