  • Encodage et transformation en formats lisibles sur Internet

    10 avril 2011

    MediaSPIP transforme et ré-encode les documents mis en ligne afin de les rendre lisibles sur Internet et automatiquement utilisables sans intervention du créateur de contenu.
    Les vidéos sont automatiquement encodées dans les formats supportés par HTML5 : MP4, Ogv et WebM. La version "MP4" est également utilisée pour le lecteur flash de secours nécessaire aux anciens navigateurs.
    Les documents audios sont également ré-encodés dans les deux formats utilisables par HTML5 :MP3 et Ogg. La version "MP3" (...)

  • 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.

  • (java.net.ProtocolException) Unable to stream video in video view. (Video which was trimmed using FFmpeg

    16 décembre 2020, par Suraj

    Hello I am using the below command to trim video using FFmpeg (trim without re-encoding)

    


    String[] command = new String[]{"-y", "-i", original_path, "-ss", ""+ startMs / 1000, "-t" , "" +((endMs - startMs) / 1000), "-c", "copy", dest.getPath()};


    


    Now this trimmed video is present on my server but i am not able to stream it in video view. Whereas I can play the other videos which was not trimmed using FFmpeg.

    


    Below is the code load video in videoview

    


    VideoView videov = findViewById(R.id.videov);
Uri uri = Uri.parse("http://x.x.xxxx.xxxx:8000/xxxxxApp/media/xxxx/1608121174332.mp4");
videov.setVideoURI(uri);
videov.start();


    


    Also I can play the same video in webview control.

    


  • Generated ffmpeg video seems to be not a real video file

    18 septembre 2020, par asored

    I try to create a video with ffmpeg and save it to the device with gallery_saver package for Flutter.

    


    The ffmpeg command works well and the video is created. But GallerySaver does not save it. As result I get no error, but a false boolean for the success argument.

    


    This is the ffmpeg output. Is this a valid video mp4 file ?

    


    Restarted application in 683ms.

    This are my ffmpeg commands :

    


    First I create a video from images in a folder

    


    -r $settingsFps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -pix_fmt yuv420p $tempPath/$videoFileName.mp4

    


    Than I add audio to the video

    


    -i ${finalSong.path} -i $videoPath -shortest $tempPath/$newVideoFileName.mp4

    


  • Slowing or speeding up video or altering frames in video to set video length

    18 novembre 2022, par user19019404

    Using ffmpeg is there a way to change the length of the video without losing frames ?
That is, I want all my videos to be 5 minutes long. Due to CPU processing and other issues (external videos received) some videos are between 2 and 4 minutes minutes, some videos are between 6 and 8 minutes. I don't seem to have lost any frames and they are all intact, just some videos play a bit slower than real seconds and some play faster.

    


    I want to change the speed of the video so that they all end up being exactly 5 minutes. So if I go 2 minutes 30 into the video we are always at the halfway point.

    


    Is this something that can be achieved with ffmpeg ?

    


    Thanks
