    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) (...)

  • ffmpeg missing image frames in generated video from images

    4 août 2013, par sihrc

    Similar question here, but not yet answered.

    Problem :

    I'm combining images (.png) of same resolution/size (they all came from the same matplotlib.pyplot), but the resulting video is missing several frames.

    Command :

    ffmpeg -f image2 -r 1 -i .\\images\\image%02d.png -c:v libx264 -r 30 .\\images\\output.mp4

    Resulting Video

    • Length of 0:09
    • Missing more than half the images

    Images

    • .\images
      • image00.png
      • image01.png
      • image02.png
      • image03.png
      • image04.png
      • image05.png
      • image06.png
      • image07.png
      • . . .

    Notes :

    I followed examples from here. I'm new to using ffmpeg, so I may not be completely sure of what each of the command line options I've used means, though I have a pretty good idea.

    Thanks, any help/advice/suggestions will be greatly appreciated. I am also perfectly willing to provide further information that may help resolve this issue.

  • Unwarping 180 VR Footage with FFmpeg v360 Filter

    5 avril 2021, par Ted Wilmont

    I am struggling at present. I have searched high and low for days and can't find a command that achieves what we want to do.

    


    We have stereoscopic 180 degrees VR footage in a side-by-side equirectangular format that we want to convert to flat so we can process using further AI software.

    


    We have already split the file in half across the width using FFmpeg so we have a "right" eye and a "left" eye video file.

    


    For each video file, we need to convert the 180-degree equirectangular footage to a flat, unwarped video file using FFmpeg (and the v360 filter).

    


    We've tried the following for example :

    


    ffmpeg -i 2LEFT.mp4 -vf "v360=input=equirect:ih_fov=180:iv_fov=180:output=flat" 2LEFTTEST.mp4


    


    However, this results in a very warped/misaligned video.

    


    Some command examples, tips, suggestions as to convert the now monoscopic 180-degree equirectangular footage to a flat video file will be greatly appreciated.

    


    Thank you for your help in advance.

    


  • ffmpeg : `ffmpeg -i "/video.mp4" -i "/audio.m4a" -c copy -map 0:v:0 -map 1:a:0 -shortest "/nu.mp4"` truncates, how to loop audio to match videos ? [closed]

    18 avril 2024, par Swudu Susuwu

    This is with "FFmpeg Media Encoder" from Google Store (Linux-based Android OS), but it has all the commands of ffmpeg for normal Linux.

    


    -shortest truncates the video to match the audio, and -longest has the last half of the video not have audio (for videos twice as long as audio,)

    


    what to use to loop audio (to match length of video with this) ?

    


    Video length is 15:02, so used ffmpeg -i "/audio.m4a" -c copy -map 0:a:0 "/audionew.m4a"-t 15:02 -stream_loop -1`, but got errors.
