  • 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.

  • FFMPEG. Concatenate videos with a intro and music

    12 juillet 2019, par Micky

    I’m trying to merge videos with an intro and a background music.

    The intro.flv is a short file with video and audio.
    The other videos are without audio.
    ambientmusic.mp3 is audio to add to subsequent videos.
    A short fade for each file.

    ffmpeg -i intro.flv -i 0.mp4 -i 1.mp4 -i 2.mp4 -i ambientmusic.mp3 -filter_complex "[0] fade = in: 0: 25 [v0]; [1] fade = in: 0:25 [v1]; [2] fade = in: 0: 25 [v2]; [3] fade = in: 0: 25 [v3]; [v0] [v1] [v2] [v3] concat = 4 [v] "-map" [v] "-map a ./output/final.mp4

    Unfortunately the code only loads the first audio. Same result as

    -map 0: a

    If I use this instead it loads ambientmusic.mp3 on the whole video.

    -map 4: a

    But I’d like the audio of the Intro followed by the ambientmusic.mp3

    -map 0: a -map 4: a

  • FFmpeg : animate image size to match music loudness

    22 juillet 2019, par skitzo

    This is for a script to generate Instagram video content. I have a script that merges an audio clip, video clip, and a logo centered throughout the whole output video’s duration.

    Goal : make the logo change size to match the audio waveform. The logo should look like it’s reacting to the beat.

    How can I achieve this using FFmpeg ? I don’t know if FFmpeg has this capability. Perhaps I could

    1. Use another library to get a volume array of the audio clip

    2. Generate an array of image sizes for the logo based on that volume array

    3. Read that array with FFmpeg ?

    1 and 2 are definitely possible but I don’t know how to approach step 3.

    Here’s the current command in my script that merges audio, video, logo, and crops the video into a square.

    ffmpeg -i video_path -i logo_path -i audio_path -filter_complex "[0:v]scale=-2:720,crop=500:500[bg];[bg][1:v] overlay=(W-w)/2:(H-h)/2" -      pix_fmt yuv420p -map 0:v -map 2:a -shortest out_path

  • Mix voiceover and background music with delay and volume

    6 août 2019, par oldman

    I don’t master ffmpeg but I really need to mix a voiceover with a background song.

    The voiceover must start 5 seconds after the song, and must end 5 seconds before the song ends.

    The music volume must be loud for the first 5 seconds and the last 5 seconds, but during the voiceover it should remain low.

    Searching the internet, the closest I could come to my goal was this :

    ffmpeg -i music.mp3 -i voiceover.mp3 -filter_complex "[0]asplit[a][b]; [a]atrim=duration=5,volume='1-max(0.25*(t-13),0)':eval=frame[pre]; [b]atrim=start=5,asetpts=PTS-STARTPTS[song]; [song][1]amix=inputs=2:duration=shortest:dropout_transition=0[post]; [pre][post]concat=n=2:v=0:a=1[mixed]" -map " "[mixed]" output.mp3

    Could someone help me complete this script ?
