  • 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.

  • c# using pipes to get output stream

    1er janvier 2017, par lilscarecrow

    I am trying to pipe youtube-dl output to ffmpeg as input, but cannot seem to get the piping part to work. In normal cmd, I can do something like

     C:\YT\youtube-dl.exe -o - https://www.youtube.com/watch?v=L4aLQ0ki9Tk | ffmpeg -i pipe:0 -f asf pipe:1

    but in c# this doesn’t work. Currently, I have c# create 2 processes :

    one for youtube-dl

    C:\YT\youtube-dl.exe -o - https://www.youtube.com/watch?v=L4aLQ0ki9Tk

    and another for ffmpeg

    ffmpeg  -i {yt.StandardOutput} -f s16le -ar 48000 -ac 2 pipe:1

    The problem is with the {yt.StandardOutput} (where yt is the process name of the youtube-dl process and -i specifies the input file/stream). Using pipe:0 doesn’t work either and I am not sure how to link the piped output of the first to the input of the second.

  • Architecture of video-based service for mobile phones

    27 juin 2015, par David Azar

    I guess this is more of a conceptual question than a technical one.

    I’m trying to figure out the best way to upload short videos to a server and also be able to download them and watch them on both Android and iOS.

    Lets focus on Android for the moment.

    I’ve done some experiments, and my results have been :

    • I’m able to compress 12-14MB video down to 500KB using FFMPEG lib with pretty good results in quality, but it takes about 12 seconds.

    • Next, im uploading those videos to my Parse backend as ParseFile to store them.

    • Finally, i can download them and watch them with no problem using a VideoView widget.

    Now, for the tests i’ve been running, these are great results. But i want to see if there is a better way to manage and scale all of this.

    My questions are :

    • Is there a better, lighter way to compress video ?

    • Is Parse the right way to go ?

    • How can i stream videos instead of downloading them and storing the on local storage before playing them ? i know this will cause my app to use significant space on disk and i dont want that.

    • How do big companies do this kind of tasks ?

    I’ve heard Amazon S3 is a cool thing for projects like this one, also Google Cloud Platform. I want to understand the best approach before building everything so i can do it the right way and also, provide the absolute best user experience for watching these videos.
