  • 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.

  • Loss less conversion using FFMPEG in react native while adding logo to video

    6 décembre 2019, par Rishav Kumar

    I am using RN-FFMPEG to embed a thumbnail in a video using FFmpeg.
    The problem is that the video quality is highly deteriorated while adding a logo.
    Also, the issue is logo gets highly stretched and distorted in landscape videos but works great in portrait video.

    Can someone help me to have a max-width and max-height to the watermark along with high processing time with lossless conversion ?

    RNFFmpeg.execute('-i ' + video + ' -i ' + logo +' -filter_complex overlay=main_w-overlay_w-25:main_h-overlay_h-25 -codec:a copy /storage/emulated/0/ABC/ABC-' + name + '.mp4')

    This is my FFMPEG code

    Here, video is path of video file.
    logo is path of the watermark
    name is any random number

  • ffmpeg compare a png logo with video except png's transparent background pixels

    19 décembre 2022, par Thm Lee

    I want to find frames with the logo image from video, and to concat theses frames without commercials for getting ad-free video.
I tried this first by using ffmpeg & jpg logo image.

    


    ffmpeg -i input.mp4 -loop 1 -i logo.jpg -an -filter_complex crop=47:25:639:24,"blend=difference:shortest=1,blackframe=95:60" -f null -


    


    And it works, but in the case by case, less accurate with blackframe setting number.
So, for getting more accuracy I tried png logo image with transeparent background.

    


    ffmpeg -i input.mp4 -loop 1 -i logo.png -an -filter_complex crop=47:25:639:24,"blend=difference:shortest=1,blackframe=95:60" -f null -


    


    But on the contrary of my idea, the results came out worse than jpg logo. It seems that the cause is why ffmpeg compare the png's transparent background part pixels too with video.

    


    Is there a way to compare png logo with video except png logo's transparent part pixels ?

    


    I'd appreciate your advice, thank you.

    


  • How to smoothly move logo from left to right using FFMPEG ?

    1er avril 2020, par Andrew00

    I have 30 mins video and a png logo. I want this logo to move left corner to right on top throughout the video. I tried to do this using overlay, where x = n (current frame) / constant, but it moves choppy, by pixels.
How to move an overlay smoothly ?
