  • 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" (...)

  • How to build a daemon to encode video files on S3 ?

    4 avril 2013, par Yuval Cohen

    I am interested in running a daemon to go over user uploaded video files and encode them in an optimal format (and add some watermarks).

    I was considering services such as Zencoder, Encoding.com, Amazon's encoding service but some lack overlaying capabilities and some are just too expensive for our (big) volumes.

    I want to build a daemon that encodes videos that are located on S3 once users upload them.

    The solution I thought of would be Python Heroku servers using Celery for a task queue to keep track of the encoded files and ffmpeg to do the actual work. However, I ran into troubles compiling ffmpeg for Heroku (with libass support, so the basic ffmpeg bins aren't enough).

    What approach/technology stack would you consider for this mini-project ?

    Thanks !

  • Fix flv files that stop early

    19 octobre 2012, par Xonar

    I downloaded some flv videos some time ago and when watching them they stop at a point. If I skip past that point they continue playing fine up until another point which I can then skip past again (and the cycle goes on until the end of the video)

    I already tried

    avconv -i input.flv -acodec copy -vcodec copy -g 1 output.flv

    To my understanding from reading alot of mostly useless posts regarding this issue the there isn't any keyframes in my metadata and then stop when there is a bad frame.

    I tried setting -g higher but output.flv stops at the same point as where the original file stops for the first time. Is there any tool that can fix this.

    I can't remember where the original links are located and re-downloading isn't a option and as you can see my re-encoding attempts has failed.

    I am using Linux Ubuntu, so I can't use the Windows tools that are available.

  • How to trim the beginning of a video with ffmpeg without transcoding the whole stream ?

    29 mai 2018, par Gabriel Diego

    To remove the first 10 seconds of a video without any transcoding I can use the following command :

    ffmpeg -i input.webm -vcodec copy -acodec copy -ss 10 output.webm

    The problem is that if the key frames are located at 8 seconds then at 12 seconds, the video will start from the 8th second. If I do the following I will get the correct timing, but the whole stream will be transcoded :

    ffmpeg -i input.webm -ss 10 output.webm

    Is there any way (using avcodec of ffmpeg) to transcode only the part from the 10th to the 12th second then copy the rest of the stream ?
