    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) (...)

  • ffmpeg cut the video and get accurate begining time of the result

    1er décembre 2022, par Pavlo Sharhan

    I do the cut via :

    


    ffmpeg -i  long_clip.mp4 -ss 00:00:10.0 -c copy -t 00:00:04.0 short_clip.mp4


    


    I need to know the precise time where did the ffmpeg do the cut (Time of the closest keyframe before the 00:00:10.0)

    


    Currently, I'm using the following ffprobe command to list all the keyframes and select the closest before 00:00:10.0

    


    ffprobe -show_frames -skip_frame nokey long_clip.mp4


    


    It works extremely slow (I run It on Jetson Nano, and It is a few minutes to list the keyframes for 30 sec video, although the cutting is done in 0.2seconds)

    


    I hope there is the much faster way to know the time of the keyframe where ffmpeg does the cut, at least because ffmpeg seeks to this keyframe and cuts the video less than in half a second.

    


    So in other words the question is : How to get the time of the keyframe where ffmpeg does the cut not listing all the keyframes ?

    


  • Using moviepy, how can I splice up long videos into 8-second bits ?

    18 septembre 2020, par ekinugurel

    relatively new python user here. I'm trying to use moviepy to splice up 5 min long videos into 8-second bits. I used the code in this thread to extract subclips and it works. I did the following to make it a loop that covers the whole video, but I only get one 8-sec video as an output :

    


    from moviepy.video.io.ffmpeg_tools import ffmpeg_extract_subclip
videopath = '../img/videos/Mopac+Cesarchavez-1.m4v'

for sec in videopath:
    sec = 0
    ffmpeg_extract_subclip(videopath, sec, sec+8.00, "../img/videos/subclips/testclip.mp4")
    if sec == 327:
        break


    


    Do I need to specify a naming convention so that my output isn't just one video ? How would I do that ?
