  • 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.

  • Want to convert my 16:9 size MKV video to 4:3 size AVI video file

    19 septembre 2012, par Bimal Rekhadiya

    I have a video in MKV format and it's size is 720x304 (16:9 ratio) size video.

    I want to convert it to AVi format (using xvid video codec). The output file size should be 480x360 (4:3 ratio) and also want to keep the original (16:9) ratio so it should be cinemascope (black areas at top and bottom).

    I am on Ubuntu linux OS so I can use mencoder, avconv(ffmpeg) or any tool that work on Linux.

    I am trying this command :

    avconv -i sample.mkv -vcodec libxvid -r 25 -b 1200 -aspect 4:3 -q 1 t.avi

    But the problem is that the video is stretched to 4:3 and I want to keep original video's ratio and want to add black boxes at top and bottom so it will look cinemascope.

    Please provide me command to do this.

  • Converted mp4 not displaying image which was added with FFMPEG [duplicate]

    3 décembre 2015, par Avi

    This question already has an answer here :

    I am converting a mp3 to a mp4 and simultaneously adding an image to it using FFMPEG.

    Here is the command I am using.

    ffmpeg -loop 1 -i ../image.jpg -i "track 1.mp3" -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest -vf scale=800:400 "track 1".mp4

    The image appears when the video is played in a web browser. However, it doesn’t appear when the video is played on Windows Media Player or on QuickTime.

    Any ideas why ?

  • Filter the video while keeping the bitrate (FFmpeg) [migrated]

    20 décembre 2013, par Timofey

    For experimental purposes, I need to filter my video (using -vf option) and change, say, brightness, but keep the same bitrate as in original video.

    Just for testing purposes, I change RGB values to make video completely black using line like this :

    ffmpeg -i input.mp4 -vf lutrgb='r=0.0*val:g=0.0*val:b=0.0*val' output.mp4

    So far, I tried to specify bitrate manually by adding -b, -minrate/maxrate and -q options to this line, but no matter what I do, FFmpeg keep reducing the br of the output video to just a few kilobytes.

    And my question is - if it's possible to keep bitrate on the same level even if if I change RGB values to be completely black (as an extreme case).
