  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • h274 : remove optimization pragma

    h274 : remove optimization pragma

    This results in warnings on compilers which don't support it,
    
objections were raised during the review process about it but went unnoticed,
    
and the speed benefit is highly compiler and version specific, and
    
also not very critical.
    

    We generally hand-write assembly to optimize loops like that, rather
    
than use compiler magic, and for 40% best case scenario, it's simply
    
not worth it.
    

    Plus, tree vectorization is still problematic with GCC and disabled by default
    
for a good reason, so enabling it locally is sketchy.

  • making screenshots from a wmv video with ffmpeg in linux [closed]

    28 avril 2013, par John

    when I try to make screenshots from a wmv video it shows-
    Error while decoding stream #0.1 - frame= 0 fps= 0 q=0.0 Lsize= -0kB time=10000000000.00 bitrate= -0.0kbits/s video:0kB audio:0kB global headers:0kB muxing overhead -inf%

    the command I am using for taking the video screenshots is - ffmpeg -i name.wmv -r 1/20 %03d.jpg

    I am using ffmpeg in linux, the video in question was originally encoded with Windows Media Video 9 and I can screenshot the video fine in windows but I cannot get it to work in linux.

    mediainfo shows the following - Video Format : VC-1 - Codec : WVC1, Microsoft

    ffmpeg -codecs|grep wmv shows that the wmv codec is already installed.

    avi, mpeg, mpg, mov and mp4 videos are all working fine, its only wmv file types which gives me this error so what can I do now ?

    thanks

  • avutil/opt : Print out numeric values of option constants

    17 septembre 2019, par Soft Works
    avutil/opt : Print out numeric values of option constants

    It's often not obvious how option constants relate to numerical values.
    
Defaults are sometimes printed as numbers and from/to are always printed as numbers.
    
Printing the numeric values of options constants avoids this confusion.
    
It also allows to see which constants are equivalent.
    

    Before this patch :
    

      -segment_list_type <int>        E........ set the segment list type (from -1 to 4) (default -1)
    
     flat                         E........ flat format
    
     csv                          E........ csv format
    
     ext                          E........ extended format
    
     ffconcat                     E........ ffconcat format
    
     m3u8                         E........ M3U8 format
    
     hls                          E........ Apple HTTP Live Streaming compatible
    

    Afterwards :
    

      -segment_list_type <int>        E........ set the segment list type (from -1 to 4) (default -1)
    
     flat            0            E........ flat format
    
     csv             1            E........ csv format
    
     ext             3            E........ extended format
    
     ffconcat        4            E........ ffconcat format
    
     m3u8            2            E........ M3U8 format
    
     hls             2            E........ Apple HTTP Live Streaming compatible
