  • Support de tous types de médias

    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) (...)

  • 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 (...)

  • How to Compile FFmpeg with x264 and libfdk-aac for Android

    12 novembre 2016, par Codeveloper

    Everyone.

    Please understand that i use the wrong english.

    I want to make encoding application using FFmpeg.

    I was successfully building NDK with FFmpeg.

    However, to encode H.264 video made had failed( Codec not found.. ).

    I was learned that libx264 is need encode H.264 and libfdk-aac is need encode AAC.

    so I tried to build the libx264 and libfdk-aac, But does not easily cross-compile.

    Please tell me what I did wrong.

    My Development Environment

  • ffmpeg : -copyts makes -t stop at timestamps, not duration

    30 juillet 2017, par arielCo

    From

    -t duration (input/output)

    When used as an input option (before -i), limit the duration of data read from the input file.

    When used as an output option (before an output url), stop writing the output after its duration reaches duration.

    So this should yield a 1-minute file with timestamps starting at 1:49, right ?

    ffmpeg -y -copyts -ss 1:49 -i ~/Videos/input.mkv -c copy -t 1:00 timing-1m49s.mkv

    Wrong. It outputs a file with no frames :

    -rwxrwx--- 1 root users 805 Jul 30 01:36 timing-1m49s.mkv

    I have to specify -t 1:49 or more, and e.g. -t 1:55 produces a 6-second file that starts at 0:00 and according to the metadata should last 1:55.

    I arrived at this point trying to extract a clip and add subtitles in the same command, but this minimal case looks to me contrary to the documentation.

  • How to use FFmpeg and GeForce Hardware to decode and encode 4K MKV movie to 1080p [closed]

    27 janvier 2023, par slyfox1186

    I am struggling with the instruction provided to convert a 4k Movie to 1080p so I can run it easier on my plex server.

    


    I have a Geforce 1080Ti and have enable cuda and all the necessary options when building ffmpeg.

    


    I keep getting a weird error and I am stuck at the below point.

    


    Here is my code that I am working on currently

    


    REM @ECHO OFF
