  • 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.

  • Convert video to exactly the same stream type of other video in ffmpeg

    14 avril 2014, par user1750371

    Maybe this is a silly question, didn't manage to find a clear answer anywhere.

    I need to use ffmpeg to convert a given video to exactly the same format another video has, including bitrate, video and audio codecs... everything. The goal is to concat both videos into a single file, independently of the original formats.

    Is there an easy way to do this or do I have to build a complex command line input specifying all parameters ?

    The concat demuxer is not enough... maybe something with filter_complex ?

    Thanks and sorry for the bother.

  • FFMPEG trim video resulting not moving videos and black video with audio

    13 juin 2023, par Rafliii

    I tried to trim my video based on start and end time with the following code :

    


    ffmpeg -ss 02:06:30.500 -to 02:06:32.417 -i movie.mp4 -c copy output.mp4

    


    The output video is not moving video and some of them are black videos with audio. What should I do ?

    


    enter image description here

    


    What should I do ?

    


  • How to put watermak on video with FFMPEG,without resizing the watermark because of video resolution ?

    22 mai 2014, par Shahbaz Younis

    I’m looking for a way that the watermark picture does not get resized,if the video resolution is high or less. Right now I have this problem, if I upload a video like 720p the watermark is really small and when I upload a video that is 240p the watermark is really big. I would just like it to be only one size. Can it do that automatically ? So no matter what the resolution is the of the video the image does not resizes and stays where I put it ? Here’s the code I’m using right now

    if ($ffmpeg_ver == "old") {
    
                    $watermark = '-vf "movie='.$tv_logo_path.' [watermark]; [in][watermark] overlay=10:10 [out]" ';
    
            } else { 
    
                    $watermark = '-i '.$tv_logo_path.' -filter_complex "overlay=10:10" ';
    
            }
