  • 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.

  • Merging two mp4 videos using ffmpeg

    12 novembre 2018, par kristian zivkovic

    I want to concatenate two mp4 videos using ffmpeg and i am a newbie in this area. I have tried to concat them using several commands and one of them is like this :

    ffmpeg -i "jingle.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts "out/jingle.ts"
    
ffmpeg -i "logo_jingle.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts "out/camera_video.ts"
    

    
ffmpeg -i "concat:out/camera_video.ts|out/jingle.ts" -bsf:a aac_adtstoasc -vcodec output.mp4

    The result is that the second video last for a minute and it shows only black screen and it actually lasts 5 seconds. I also noticed that videos have different parameters so i tried to harmonize some of the parameters but with that the second video is showing but without sound and still lasts a minute.
    Here are the video parameters.

    Can you tell me how to harmonize these videos and merge them in this particular example ?

    I am using ffmpeg to capture video while running protractor scripts. Below ffmpeg code is working fine, when I directly run in windows from command line and able to create the video.

  • ffmpeg amix filter on mp3 with image

    20 novembre 2018, par cutoffurmind

    I use ffmpeg to concatenate 2 mp3 files with amix filter (see full log).

    It works fine for mp3 files without any meta but it fails with mp3 files with cover image in meta, result file length is less then 1 second.

    How could I fix it in same command ?

    Here is full log :

    localhost:Music user$ ffmpeg -i input.mp3 -i /opt/docker/tag_long.mp3 -filter_complex amix=inputs=2:duration=shortest,volume=2 -codec:a libmp3lame -q:a 5  out.mp3 -report
