  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Place FFMPEG videos side by side, allign by frame number

    4 mars 2017, par Eduardo Perez

    So, I have 2 videos I would like to place side by side. I would like to align them by a frame number that I know for each video, assuming both videos have the same FPS. The frame numbers were found using the following command.

    ffmpeg -i "input.mp4" "output/%08d.jpg"

    So, let’s say I know the frame number I want to align for Video A is 126, while for Video B the frame number is 179. I want to align the videos side by side with these two frames lining up, so that the resulting video would be displaying Video A frame 126 at the same time as Video B frame 179. The resulting video also shouldn’t have any pieces from either video removed, so if one of the videos hasn’t started or isn’t finished, the resulting video keeps playing the active video, rather than having only the times when both videos are supposed to be playing. I also want to align both audio tracks as well.

    For this question I would prefer a single-command solution where I only need to input the videos and frame numbers I want to align, rather than having to do several steps manually.

    I really wish to have a watermark on all videos which are uploaded to my website.

I couldn't find any other link/video which explains. Does anyone have an idea on how it works ? A good explanation could help me and others in the future alot. Thank you

    


  • FFMPEG : Concatenating two videos and adding audio only to the second video

    29 septembre 2023, par Huzefa Tahir

    I have two videos v1 and v2 which I want to concat. I also want to add audio a2 to the second video. v1 may or may not have an audio. How can I do that in one ffmpeg script ?
This is how the output should be like :
| V1 | V2 |
| a1 ? | a2 |

    


    I am having trouble placing the audio a2 at the start of the v2. I can't seem to find a filter that does this and -map doesn't seem to work with this either as it places a2 at start of v1.
