  • 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.

  • Converting a YUV file to .mp4 using ffmpeg for a beginner

    11 mars 2014, par GreenGodot

    I'm a newbie when it comes to linux and ffmpeg but I need to use Evalvid to stream a video file. I want to stream a file for around 500 seconds. My plan is to download one of the videos from here :

    http://media.xiph.org/

    For this example I downloaded a video of Big Buck Bunny (in this case the 480p version). it came in an xz which I used unxz on, getting me a .y4m file which I used ffmpeg to convert to a YUV file.

    ffmpeg -i big_buck_bunny_480p24.y4m bbb.yuv

    My problem is right here, I try to use examples from this site but they don't work. What is the exact command to convert it to a .mp4 file using ffmpeg or are their easier alternatives to use ?

    I have tried :

     ffmpeg -f rawvideo -s:v 1920x1080 -r 25 -i bbb.yuv -c:v libx264 output.mp4

    and this starts the conversion process but after 5 minutes I get an invalid buffer value error and the output is a mess of colours.

  • Android NDK. How to play video.

    4 février 2014, par bukka.wh

    I need to play video on Android device (different formats). As I have understand, the best way is to use Android NDK with specific libraries that can play video. I have done some basic examples to understand NDK usage, but I don't know what to do next. As I have understood, I must install ffmpeg first of all.
    So I have the following questions given below :

    1. I need to have ffmpeg (the best way is to use Linux, not Windows,
      because in Windows there are some troubles with its installation).
    2. How to play sound of video ?
    3. I have read that some open-source libraries can play video without any efforts. My job is to give them byte-array or path to video on SD. Is this right ?

    So, can anyone help me and explain basic ways how to play video with ndk, may be some basic plan or links ?
    Thank you very much for interest to my question !
