  • 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" (...)

  • Find a great Google Tag Manager alternative in Matomo Tag Manager

    29 avril 2020, par Joselyn Khor — Analytics Tips, Development, Marketing, Plugins

    If you’re looking for a tag management system that rivals Google’s, then Matomo Tag Manager is a great Google Tag Manager alternative that takes your tracking to the next level.

    What’s a tag manager ?

    If you’re not familiar with Google Tag Manager or Matomo Tag Manager – they’re both free tag management systems that let you manage all your website code snippets (tags) in one place. 

    Tags are typically JavaScript code or HTML that lets you integrate various features into your site in just a few clicks. For example : analytics codes, conversion tracking codes, exit popups and surveys, remarketing codes, social widgets, affiliates, and ads. With a tag manager, you get to easily look into and manage these different tracking codes.

    Why use a tag manager ?

    Tag management systems are game changers because they let you track important data more effectively by easily adding code snippets (tags) to your website. 

    By not needing to hard code each individual code you also save time. Rather than waiting for someone to make tag changes and to deploy your website, you can make the changes yourself without needing the technical expertise of a developer.

    Why is Matomo Tag Manager a great Google Tag Manager alternative ?

     Matomo Tag Manager is a great Google Tag Manager alternative. Not only does it let you manage all your tracking and marketing tags in one place, it also offers less complexity and more flexibility. 

    By tagging your website and using Matomo Tag Manager alongside Matomo Analytics, you can collect much more data than you’d be able to otherwise. 

    A bonus to using Matomo is the privacy and data ownership aspect. With Matomo you also get the added peace of mind that comes with 100% data ownership and privacy protection. You will never be left wondering what’s happening to your data. Rest assured knowing you’re doing the best to protect user privacy, while getting useful insights to improve your website. 

    And since Matomo Tag Manager is the one of the best alternatives to Google Tag Manager, you’ll gain more than you lose by having full confidence that your data is yours to own.

    Three key benefits of using Matomo Tag Manager :

    • Empowers you to deploy and manage your own tags
      This takes the hassle out of needing a web developer to hard code and edit every tag on your website. Now you can deploy tracking code on chosen pages and track various data yourself. 
    • Open up endless possibilities on data tracking
      Dig a lot deeper to track analytics, conversions, and more. Now you can implement advanced tracking solutions without needing to pay an external source. 
    • Save time and create your own impact
      With limited resources you certainly don’t want to be wasting any time having to go back and forth with an external party over what tags to add or take away. An over-dependence on web developers or agencies carrying out tag management for you, stalls growth and experimentation opportunities. With a tag management system you have the convenience of inserting your own tags and getting to a desired outcome faster. You won’t have to forgo tracking opportunities because now it’s in your hands.
  • Generating video from images and audio by FFmpeg

    24 mars 2020, par Cody

    I am new to FFmpeg and video/audio encoding. I try to use Fluent ffmpeg to generate a MP4 video from images and audio.

    There are 2 inputs only :

    If the audio duration is longer video length, just discard the excessive part of audio at the end.
    And all the images have to be shown in same duration.(i.e. The video should be in n/d FPS for n images and video with d second)

    Since the image input are not in number sequence, I use concat demuxer as input :

           let VIDEO_DURATION = 8;
           let ffmpeg = await FfmpegUtil.createCommand();
           let imageFiles: string[] = ["foo.jpg", "bar.jpg", ...]; //assume there are 67 image files
           let demuxerFile = await FfmpegUtil.createConcatDemuxerFile(imageFiles);
           let audioFile: string = "path/to/audio.wav";

           ffmpeg.input(demuxerFile)
               .inputOption(
                   "-f", "concat",
                   "-safe", "0",
               )
               .input(audioFile)
               .outputOption(
                   "-r", `${imageFiles.length}/${VIDEO_DURATION}`,
               )
               .duration(VIDEO_DURATION)
               .save("path/to/output.mp4")
           ;

    it will spawn a ffmpeg command :

    ffmpeg
       -f concat
       -safe 0
       -i path/to/demuxerFile.txt
       -i path/to/audio.wav
       -y
       -r 67/8
       -t 8
       path/to/output.mp4

    However the output file cannot be played.

    I also tried "-framerate", ${imageFiles.length}/${VIDEO_DURATION} in .outputOption(), it still output a file cannot be played and I found the frame rate always be 25 in its file property.

    Update 1 (added spawned command & ffmpeg console log) :

    spawned ffmpeg command & console log ("-r", `${imageFiles.length}/${VIDEO_DURATION}` as outputOption) :

    ffmpeg -f concat -safe 0 -i path/to/demuxerFile.txt -i path/to/audio.wav -y -r 67/8 -t 8 path/to/output_r.mp4

    file video.mp4

    then i start using this command

    ffmpeg -f concat -i ffmpeg-sound.txt -c copy final_output.mp4

    the problem is i got this from ffmpeg

    the result give me a video mp4 file with a long duration like 46:33:20 and it not work, and iam sure that both videos have same reslution.
    what i tried is to use this command to convert the video

    ffmpeg -y -i No-fade_25fps.mp4 -r 25 -s 1280x720 -c:v libx264 -b:v 3M -strict -2 -movflags faststart destination.mp4

    and when i concate them again it worked and give me result mp4 file which have a right duration and worked fine but without a sound, because the first video file i use is muted no sound in it and second one contains a sound.
    my question is how to concate those videos togther without this problem also what make the video have the problem of this long duration and when i convert them using the command line it worked ?
    first video info which is No-fade_25fps.mp4
