  • 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) (...)

  • What is the most efficient way to trim and join multiple videos in ffmpeg ?

    27 avril 2020, par Patrick Oshea

    I have a python program that downloads a bunch of .mp4 videos into a directory for me and after running a few audio matching algorithms I need to trim the videos to a minute and eventually concantenate them all together.

    



    As of right now I do the following things to a video :
Trim it to a minute
Resize the videos so they're all the same size
Apply a picture to the video
And then pad the video (this is due to a weird glitch that occurs if I try joining all the videos together which results in the audio and video not being synched)

    



    Is there any way to combine some of the steps or things I should make sure I'm doing to do this as fast as possible ? Thank you in advance !

    


  • Create a video with other videos at certain points

    7 mars 2020, par Antique Chariot

    I’ve never used ffmpeg before, and I need to do something quite complicated (in my opinion at least, this could be easy).

    Basically I need to have a black video but at certain points concatenate other videos.
    For example, at 0.00 a 3 second video, then black until 10.0 and then another video, etc etc

    The finished videos will consist of hundreds of videos and be anywhere from 1-5 minutes long.

    I’m working in Node.js, ideally using a wrapper would be best (I’m using fluent-ffmpeg currently but any will suffice), although raw commands are also an option.

    Any ideas are appreciated !

    Edit : also, say a 5 second video is at 0.00, and a 10 second video is at 1.00, I’d like it to overwrite the original 5 second video

  • How to merge four videos on one screen with ffmpeg [duplicate]

    9 mai 2021, par Andrey Prokhorenko

    I have a video test.mp4, and I need to make it appear four times at once on a screen.

    


    Here I found a command that makes two videos appear at a time

    


    ffmpeg -i input0.avi -vf "movie=input1.avi [in1]; [in]pad=640*2:352[in0]; [in0][in1] overlay=640:0 [out]" out.avi


    


    But it doesn't work with mp4 videos, and I need four videos at a time.
