  • 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.

  • piping in ffmpeg in c#

    6 septembre 2013, par user846281

    I have a directory full of images. I convert these images into a flv file. Then i convert that flv into a mp4 file (i have my reasons to do this). I can achieve this OK using the process method in c#. Currently i call this twice (with different arguments) First call it converts the images to flv and the second call converts that flv to mp4. is there a way to do this in 1 process and not actually write the flv to disk ?

    For example in sudo code :

    ffmpeg -allmyjpgs this.flv | final.mp4

  • How to add a title slide to a video ?

    5 septembre 2013, par Anand Chitipothu

    I'm trying to add a title slide to a video.

    I've the title image and I created a mp4 out of it using :

    ffmpeg -loop 1 -shortest -f image2 -i slide.png -i silence.wav -c:v libx264 -c:a libmp3lame -tune stillimage  -strict experimental -t ${INTRO_LENGTH} slide.mp4

    And then I joined the slide using :

    ffmpeg -i slide.mp4 slide.mpg
    
ffmpeg -i video.mp4 video.mpg
    
cat slide.mpg video.mpg > video-with-slides.mpg
    
ffmpeg -i video-with-slides.mpg video-with-slides.mp4

    But the final output file is way larger than the input video (6X or more). Is there any simpler/better way to add a title slide to a video ?

  • Find video resolution and video duration of remote mediafile

    22 février 2012, par osgx

    I want to write an program which can find some metainformation of mediafile. I'm interested in popular video formats, such as avi, mkv, mp4, mov (may be other popular too). I want basically to get :

    • Video size (720, 1080, 360 etc)
    • Total runtime of video (may be not very exact)
    • Number of audio streams
    • Name of video codec
    • Name of audio codec

    There is already the mediainfo, but in my program I want to get information about remote file, which may be accessed via ftp, http, samba ; or even torrent (there are some torrent solutions, which allows to read not-yet downloaded file).

    MediaInfo library have no support of samba (smb ://) and mkv format (for runtime).

    Also, I want to know, how much data should be downloaded to get this information. I want not to download full videofile because I have no enough disk space.

    Is this information in the first 1 or 10 or 100 KiloBytes of the file ? Is it at predictable offset if I know the container name and total file size ?

    PS : Platform is Linux, Language is C/C++
