  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • How to use ffmpeg.exe to produce a video with exact length for time from image sequence in C# ?

    15 octobre 2020, par user2186102

    We try to use ffmpeg.exe to make a video from image sequence in C#. However, we can't produce a video which has a predict length for time. For example, we want to produce a video whose length of time is one hour ; actually, the length of time is only 47 miniutes.

    



    According our understanding, the function, WriteVideoFrame(Bitmap frame, TimeSpan timestamp) of AForge.Video.FFMPEG, can solve this problem. It is because each input frame is associated with a timestamp.

    



    In ffmpeg.exe, however, we now can only use frame to as input of ffmpeg.exe.

    



    Who can show me how to write the command or parameters to input each image and the associated timestamp, the same to WriteVideoFrame(Bitmap frame, TimeSpan timestamp).

  • Mapping audio to video with ffmpeg with metadata length

    20 juin 2023, par Tomáš Kordoš

    I'm using node.js ffmpeg-static to map a video and an audio together.

    


    var VideoStream = ytdl(video, { filter: 'videoonly', quality: 'highestvideo' });
var AduioStream = ytdl(video, { filter: "audioonly", quality: 'highestaudio' });

const ffmpegProcess = cp.spawn(ffmpeg, [
  '-i', `pipe:3`,
  '-i', `pipe:4`,
  '-map', '0:v',
  '-map', '1:a',
  '-c:v', 'copy',
  '-c:a', 'aac',
  '-movflags', 'frag_keyframe',
  '-f', 'mp4',
  '-'
 ], {
  stdio: [
    'pipe', 'pipe', 'pipe', 'pipe', 'pipe',
  ],
});

VideoStream.pipe(ffmpegProcess.stdio[3]);
AduioStream.pipe(ffmpegProcess.stdio[4]);
ffmpegProcess.stdio[1].pipe(fs.createWriteStream('./out.mp4'));


    


    The saved file contains both audio and video as expected, But the length of the file is only 4 seconds when using -movflags frag_keyframe. Although the video continues after that (00:10 / 00:04)

    


    -movflags faststart Never works

    


    How do I automatically or manualy (Ytdl allows me to download the video length)set the length ?

    


    Thank you
