  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • How to show a watermark for 3 second on a MP4 using FFmpeg

    6 février 2014, par b1izzard

    I need to add a 3-second watermark to a Camera recorded video in Android. I'm using FFmpeg static build to execute the commands.

    Approach I

    I had tried the below command using latest version of FFmpeg(version N-60108-gda25a65) in my Desktop running Linux Mint, the command works fine.

    ffmpeg -y -itsoffset 3 -i input.mp4 -i myImage.jpg -filter_complex "[0:v][1:v]overlay=0:0:enable=between(t\,0\,3)"  -codec:a copy output.mp4

    In Android I'm using the FFmpegv1.2 with below config to execute the command.

     *******Starting FFMPEG
    
    ***ffmpeg version 1.2 Copyright (c) 2000-2013 the FFmpeg developers***
    
    ***  built on Mar 31 2013 23:44:57 with gcc 4.6 (GCC) 20120106 (prerelease)***

    ***  libswresample   0. 17.102 /  0. 17.102***

    Java Code to run the FFmpeg command :

    String[] ffmpegCommandToAddWatermark = { 
    
            mFfmpegInstallPath, "-y", "-itsoffset","3",
    
             "-i", INPUT_VIDEO_PATH, "-i", WATERMARK_IMAGE_PATH,
    
             "-filter_complex","[0:v][1:v]overlay=0:0:between(t\\,0\\,3)",
    
             "-strict","-2",
    
             "-codec:a","copy",OUTPUT_VIDEO_PATH};          
    
        try {
    
        Process ffmpegProcess = new ProcessBuilder(ffmpegCommandToAddWatermark)
    
            .redirectErrorStream(true).start();
    

    
        String line;
    

    
        BufferedReader reader = new BufferedReader(
    
            new InputStreamReader(ffmpegProcess.getInputStream()));
    
        Log.d(TAG, "*******Starting FFMPEG");
    
        while ((line = reader.readLine()) != null ) {
    

    
            Log.d(TAG, "***" + line + "***");
    
        }
    
        Log.d(null, "****ending FFMPEG****");
    

    
        } catch (Exception e) {
    
        e.printStackTrace();
    
        }

    The command execution failed with following error :

    ***[overlay @ 0x271f770] No option name near 'between(t,0,3)'***
    
***[AVFilterGraph @ 0x2711530] Error initializing filter 'overlay' with args '0:0:between(t,0,3)'***
    
***Error configuring filters.***

    The same command executes successfully when :enable=between(t\,0\,3) is removed, but the resulting output video has the watermark throughout the timeline, but I need watermark only for the starting 3 seconds.

    Approach II :

    I tried to convert WaterMarkImage to WaterMarkVideo

    ffmpeg -y -loop 1 -r 30 -i WaterMarkImage.jpg -b:v "4096k" -vf "scale=640:480" -t 3 WaterMarkVideo.mp4

    And then merge the WaterMarkVideo.mp4+CameraRecordedVideo.mp4 using the concat command :

    ffmpeg -y -f concat -i inputs.txt -c copy output.mp4

    The resulting output is corrupt due to BitRate,FrameRate,etc., mismatch. Any idea to solve the problem ?.
