  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • 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) (...)

  • Best language to use for AWS Beanstalk worker, for Watermarking videos

    16 juin 2017, par RAJ CHOURASIA

    I have a requirement such that, for each customer, the video content I have has to be separately watermarked and kept in the cloud. Also, this whole process is to be automated.

    The way I have figured the architecture is that :

    • I would use AWS SQS queue, to update for which Customers, which set of videos have to be watermarked
    • AWS Beanstalk worker would read the queue, pick up the videos from a S3 location, watermark the required videos and save back in a separate S3 location

    Total size of all the videos can be upto 15GB, which takes more than 24hrs to watermark, using "ffmpeg", so I will also require

    • Ability to parallel process, use multiple CPU cores if available
    • Ability to auto scale, when required

    In order to achieve this, what would be the best Language to use, to write the AWS Beanstalk worker logic ?

  • FFMPEG delay mutliple overlay videos (with different delays)

    28 avril 2019, par Bamba675

    I’m trying to overlay a video (for example a report) with different other videos or images, like hints to the facebook page or a hint to the website. These other videos or images are smaller than the original and sometimes transparent (rgba).

    I already tried to overlay multiple videos, which works pretty well :

    ffmpeg -i 30fps_fhd.mp4 -i sample.mp4 -i timer.webm -i logo.jpg -filter_complex "overlay = x=100:y=1000, overlay = x=30:y=66:eof_action=pass, overlay = x=0:y=0" -acodec copy -t 70 out.mp4

    But now, I want to start some videos or images not at the beginning of the video, instead after a period of time.
    I found flags like ’itsoffset’ or ’setpts’, but I dont know how to apply them on this ’multiple video / image overlay command’.

  • Cutting multiple videos with x amount of time from the end (ffmpeg ?)

    25 octobre 2020, par Jack Fitzpatrick

    I have no history with ffmpeg, but I am assuming this would be the right tool for the job. I am trying to cut a folder of videos with different lengths. I want to cut them all to be 12 seconds from the end. That is : on a 30 second video I would be left with 00:18 - 00:30. 00:00-00:17 would be deleted.

    


    I am on mac OS Mojave. It seems that ffmpeg is the right tool for the job to batch edit these videos. Can someone walk me through this ? I have some basic understanding but will need the code/script explained so that I can apply it to my own use. Thank you very much.
