  • 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.

  • Encode multiple files from the same Folder with Google Colab & FFmpeg

    16 août 2021, par Ptibouc77

    i made a Google colab to encode my videos, but actually i can only do files on by one.
I want to encode all video files from the same folder.

    


    I tried this but didn't seem to works

    


        import os

DIRECTORY= '/content/drive/My Drive/Videos'
for filename in os.listdir(DIRECTORY):
    if (filename.endswith(".mov")): #or .avi, .mpeg, whatever.
        os.system("ffmpeg -i {0} -c:v libx265 -crf 26 -c:a aac -b:a 160k output%d.mp4".format(filename))
        print(filename)


    


    Edit : I edited the FFmpeg command but still not workings on Google Colab.
Edit 2 : Print command only return the name of the files with the extension like "MyMovie.mov" how do i put the full path to the ffmpeg command ? I also want to put the ouput files to a subfolder named x265

    


  • FFmpeg : How to color-key all colors except blue and white ?

    21 février 2018, par DanielNg

    I know how to colorkey a specific color from an overlay video based on the documentation from FFmpeg. Here is the code I used to colorkey the black color out of a video then overlay it with a base video keeping the audio from the overlaid video :

    "ffmpeg -i " + baseVid + " -i " + overlayVid + " -y" + ' -filter_complex "[1:v]colorkey=0x000000:0.6:0.0[ckout];[0:v][ckout]overlay=shortest=1[out]" -shortest -map 1:a -map "[out]" ' + output

    However, my problem is that the overlaid video also contains other colors such as blue, white, brown, grey, green. Even though they are only small portions compared to the black that has been removed, they make the colorkeyed overlaid video look really dirty. I want to keep only the two main colors (blue and white) and removing the rest from the overlaid video. How do I do this using FFmpeg. I tried this code but it did not work.

  • FFMPEG 360 mp4 to SBS for Google cardboard

    3 mai 2022, par mike

    I've created some 360 degree mp4 videos froma GoPro max camera.
I would like to display these on Google cardboard (side by side) in the same way as Youtube, whilst modifying the playback speed with FFMPEG.

    


    I haven't found the right flags to convert the image to SBS with v360 or stereo3d

    


    Any suggestions ?
