  • 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.

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • Stripping 'actual time of day' from AVI files

    22 avril 2014, par wxJunkie

    I have TB’s of AVI|DV|VOB files. I want to run a script that will enable me to find the real start time + end time AND the navigation (latitude & longitude) that is embedded in the audio of each of the clips that I have and export the list perhaps to a .txt or .doc list. I use a SMPTE reader now that can read the time that is embedded in the video, so there has to be a script that will pull those certain criteria’s out ?

    I have ran several codes in the past that has given me :
    duration : 00:01:23.83 start : 0.0000000, bitrate 28771 kb/s etc.
    I always get ’start : 0.0000000’ for each clip and I need the real start time of each clip.

    Is this possible ?

  • Remove flicker, crop and upscale in ffmpeg

    22 août 2024, par Sabha

    I spent one full day on ffmpeg line commands by searching a lot on google but could not achieve what I wanted to and therefore I came here to seek some advice.
I have a video testinput.mpg which I believe is a mpeg-2 video. It is of 720x576 dimensions having 25 fps and a total bitrate of 4224 kbps

    


    First problem is that the exported footage is flickering which I wasn't able to remove using ffmpeg with lots of commands I tried like adjusting brightness, contrast, hue, saturation and all.

    


    Second problem was to extract the center portion which I was able to do it with the crop feature using following command.

    


    ffmpeg -i testinput.mpg -filter:v "crop=468:374" testoutput.mpg


    


    But after cropping I observed that that bitrate fell from 4224 kbps to 761 kbps and I assume this has reduced the quality of video.

    


    What I want to achieve is :

    


      

    1. Crop the video properly keeping the same quality (acodec copy vcodec copy) -> ffmpeg did not allow me to do both the things together (cropping and having same codec)

      2. 


    2. Remove the flicker from video and upscale it to 4K or HD quality so that it looks nice on big televison (preferably 4K)

      3. 


    


    I request some help on how to achieve the desired result. Can someone shed some light on it ?

    


    Here are 10 seconds sample videos on google drive that I am working on

    


    testinput.mpg

    


    testoutput.mpg

    


    Thanks
