  • 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.

  • Add several texts to ffmpeg slideshow video

    29 décembre 2016, par kostya572

    I have slideshow video created from images with :

    ffmpeg -r 60 -video_size 1280x720 \
    
-loop 1 -t 5 -i ok/image-1.jpg \
    
-loop 1 -t 2.5 -i ok/image-2.jpg \
    
-loop 1 -t 2.5 -i ok/image-3.jpg \
    
-loop 1 -t 2.5 -i ok/image-4.jpg \
    
-loop 1 -t 2.5 -i ok/image-5.jpg \
    
-filter_complex \
    
"[1:v][0:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b1v]; \

    I know that i can add text with drawtext=fontfile=OpenSans-Regular.ttf:text='Title of this Video':fontcolor=white:fontsize=24:x=(w-tw)/2:y=(h/PHI)+th; Also i know there is possibility to make text duration for example from first second to fifth second with drawtext=enable='between(t,1,5)'. How can i combine multiple texts with different durations with code provided below ?

  • Coverting JPEG images or webcam stream to video using C language with ffmpeg wrapper or any othe way

    19 décembre 2016, par Chakri

    I’m writing a C program that access webcam using linux-v4l2 to record in a video file. I’m able to take jpeg pictures using v4l2 and libjpeg. Here is the part of code :

    int jpgfile; 
    
if((jpgfile = open("/tmp/myimage.jpeg", O_WRONLY | O_CREAT, 0660)) < 0){
    
    perror("open");
    
    exit(1);
    
    }
    

    
write(jpgfile, buffer, buf.length);
    
close(jpgfile);

    I want to replace this peice of code to a ’equivalent video code’ or to convert that jpeg stream (or raw buffer stream) to a video file using libraries or through pipelining because writing to disk requires more cycles. I’ve come across ffmpeg wrappers like avcodec.h but they lack proper documentation.

    Please give me advice to convert to video file.

    doc/filters : drawtext : add example of printing texts on same baseline

    Height of canvas produced by drawtext varies depending on symbols in
    
text, so add example for printing separate texts aligned horizontally.
