  • 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.

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • How to join two image into one by ffmpeg ?

    19 juin 2016, par n2v2rda2

    There are two images : a.jpg and b.jpg.

    I just want to know how to join them into one image using ffmpeg.

    How should I finish the ffmpeg -i a.jpg -i b.jpg command to get a c.jpg output image ?

    This is an example of what I am trying to achieve :

    1. a.jpg

      a.jpg

    2. b.jpg

      b.jpg

    3. c.jpg

      a.jpg and b.jpg side-by-side on one image

  • Covert raw image buffer into JPEG using LIBAVCODEC

    20 janvier 2014, par user846400

    I have a raw image buffer (in memory) captured from a camera that I want to convert into JPEG (for reducing size). The problem is that saving these images into .pgm format results into a huge file size that I can't afford due to the memory limitations and latency involved in saving a huge file of this size (a constraint in the application I am working on).

    I want to know how do I compress/encode an image buffer into .jpg format using LIBAVCODEC ? My image capture code is in C.

  • Fade in image on existing video [closed]

    2 décembre 2024, par csphmay

    I'm currently trying to create a video which has a background image and a mp3 set for background audio and now I want to achieve to add a second image which fades in over 5 seconds. The result should be a video where the background image is shown and the second image is laying over it (The second image is basically a logo which I would like to place in the bottom right corner).

    


    To this point I wasn't able to achieve the result described above with a single FFMPEG command.
With the following two commands I generate the video with the first background image and with the second command I try to add the overlay which should fade in from 0-5 seconds. Unfortunately the second video will be black for the first 5 seconds and afterwards just the background image fades in from 5-10 seconds and the overlay is not even shown.

    


    ffmpeg -framerate 25 -loop 1 -t 00:04:52 -i background.jpg -i wedding.mp3 -c:v libx264 -c:a aac -pix_fmt yuv420p -shortest -y part1.mp4


    


    ffmpeg -i part1.mp4 -framerate 25 -loop 1 -t 00:04:52 -i overlay.png -filter_complex "[0:v][1:v]overlay=enable='between(t,5,4.52)':shortest=1,fade=t=in:st=5:d=5[v]" -map "[v]" -map 0:a -c:v libx264 -c:a aac -pix_fmt yuv420p -y output.mp4


    


    Is there a way to make this work with FFMPEG (at best only with one command) ?
