  • 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.

  • How to encode grayscale video streams with FFmpeg ?

    26 octobre 2014, par Gearoid Murphy

    I’ve got a grayscale video stream coming off a Firewire astronomy camera, I’d like to use FFmpeg to compress the video stream but it will not accept single byte pixel formats for the MPEG1VIDEO codecs. How can I use the FFmpeg API to convert grayscale video frames into a frame format accepted by FFmpeg ?

  • Multiple video sources combined into one

    28 septembre 2011, par Oded

    I am looking for an efficient way to do the following :

    Using several source videos (of approximately the same length), I need to generate an output video that is composed of all of the original sources each running in its own area (like a bunch of PIPs in several different sizes). So, the end result is that all the original are running side-by-side, each in its own area/box.

    The source and output need to be flv and the platform I am using is Windows (dev on Windows 7 64bit, deployment to Windows server 2008).

    I have looked at avisynth but unfortunately it can't handle flv and non of the plugins and flv splitters I have tried worked.

    My current process uses ffmpeg in the following manner :

    1. Use ffmpeg to generate 25 png's per second per video, resizing the original as needed.
    2. Use the System.Drawing namespace to combine each set of frames into a new image, starting with a static background, then loading each frame into an Image and drawing to the background Graphics object - this gives me the combined frames.
    3. Use ffmpeg to combine the generated images to a video.

    All this is very IO intensive (which is my processing bottleneck at the moment) and I feel there must be a more efficient way to reach my goal. I do not have much experience with video processing, and don't know what options are out there.

    Can anyone suggest a more efficient way of processing these ?
