  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • 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) (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • How to extract orientation information from videos ?

    23 décembre 2016, par Sid

    After surfing through tons of documentation on the web it seems that the iPhone always shoots the video at a 480x360 aspect ratio and applies a transformation matrix on the video track. (480x360 may change but its always the same for a given device)

    Here is a way of modifying the ffmpeg source within a iOS project and accessing the matrix http://www.seqoy.com/correct-orientation-for-iphone-recorded-movies-with-ffmpeg/

    Here is a cleaner way of finding the transformation matrix in iOS-4
    how to detect (iphone sdk) if a video file was recorded in portrait orientation, or landscape

    How can the orientation of the video be extracted in either of the options below -

    - iOS 3.2

    - ffmpeg (through the command line server side)

    - ruby

    Any help will be appreciated.

  • Convert video from FFMPEG than video is rotated [duplicate]

    25 octobre 2016, par user7050166

    This question already has an answer here :

    I have created one Application API, in this Application API When i have upload video from file manager than video is rotated but when i have capture and direct upload than video is perfect work.

    i have use this command transpose=1 but capture video is rotated 90 degree when upload and if i have remove this command than file manager video is rotated.

    so please give me solutions.

    /usr/bin/ffmpeg -i video.mp4 -i watermark.png -filter_complex 'overlay=10:10' -s 640x1280 -b 512k -vcodec mpeg1video -acodec copy -vcodec h264 -acodec aac -strict -2 output_video.mp4

    file manager upload video is auto rotated on 270 degree, i have not use any rotated command but capture video is work perfect.

  • ffmpeg-Error "Buffer queue overflow, dropping." when merging two videos with delay

    20 septembre 2016, par Stefan Urbansky

    I want to merge two videos (as example the iphone video from https://peach.blender.org/trailer-page/). The videos are placed on an background image with the overlay filter and the second video starts 3 seconds later.

    And I need that the audio is mixed.

    Here is my code :

    ffmpeg \
    
    -loop 1 -i background.png  \
    
    -itsoffset 0  -i trailer_iphone.m4v \
    
    -itsoffset 3  -i trailer_iphone.m4v \
    
    \
    
    -y \
    
    -t 36 \
    
    -filter_complex "
    
        [2:a] adelay=3000 [2delayed];
    
        [1:a][2delayed] amerge=inputs=2 [audio];
    
        [0][1:v] overlay=10:10:enable='between(t,0,33)' [lv1];
    
        [lv1][2:v] overlay=10:300:enable='between(t,0,36)' [video]
    
    " \
    
    \
    
    -threads 0 \
    
    -map "[video]" -map "[audio]" \
    
    -vcodec libx264 -acodec aac \
    
    merged-video.mp4

    I get the error message :

    [Parsed_overlay_3 @ 0x7fe892502ac0] [framesync @ 0x7fe892502b88] Buffer queue overflow, dropping.

    And the merged video has many dropped frames.

    I know that are some other posting with this error message. But the suggested solutions doesn’t work for me.

    How can I fix the problem ?
