  • 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) (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • FFmpegWrapper - get exact segment start or end times ?

    21 décembre 2015, par Stefan Kendall

    Right now, I’m using FFmpegWrapper, and I watch for changes via kernel events. This gets the segments when they’re created, but I’m not sure how accurate this is.

    Really, I want to know the presentation timestamp of when the hls segment is created. Right now I capture and encode frames manually and write packets via
    FFOutputFile *outputFile;
    [_outputFile writePacket:_packet error:&error];

    So I have each frame’s presentationTimestamp, but I don’t know which frame goes to which eventual MPEG-TS segment. Once I write to the FFOutputFile, it’s a blackbox to me.

    Is there any way to know what frame will go to what segment ahead of time, or get a callback from FFmpeg when a new segment is written ?

    Exact times are ideal. Close times are better. Watching the directory for new files via kernel events is what I have right now, so any solution of that time magnitude isn’t useful.

  • Can I pass a list of image into the input method of ffmpeg-python

    31 janvier 2023, par se7en

    My task involves using ffmpeg to create video from image sequence.
the code belows solves the problem.

    


    import ffmpeg

video = ffmpeg.input('/path/to/images/*.jpg', pattern_type='glob',framerate=20).output(video.mp4).run()


    


    However since the image data we are getting follows the pattern

    


    1.jpg,
2.jpg,
3.jpg
.
.
20.jpg
.
.
100.jpg


    


    the video get created with the glob pattern 1.jpg, 100.jpg, 11.jpg, 12.jpg, ... 2.jpg, 20.jpg, 21.jpg ... which is very unpleasant to watch.

    


    Is there anyway I can pass a list or anything else aside a path/glob pattern where the images are sorted in order.
Also as a bonus I will be happy if I can choose which files to add as an the input method input()

    Tried this one got error : 'not found option rotate'

    


    ffmpeg -i img001.jpg \
  -vf "zoompan=z='min(zoom+0.0005,1.5)':\
               y='if(gte(zoom,1.5),y,y+1)':
               x='x':
               d=225:
               rotate=-3*PI/180" \
  -c:v libx264 -t 10 output4.mp4


    


    Tried also this one, no luck, not what i wanted :(

    


    ffmpeg -i img001.jpg

               x='if(gte(zoom,1.5),x,x+1)':
               d=225" \
  -c:v libx264 -t 10 output4.mp4
