    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants.

    doc : add script to compute texi files dependencies

    Replace the inline awk script with a Perl script which tracks the
    
dependencies recursively.
    

    This allows to correctly track dependencies for files including files
    
with a second level include (for example : ffmpeg-devices.texi ->
    
devices.texi -> outdevs.texi).
    

    This also adds a dependency on perl for computing the dependencies, which
    
should not be a problem since perl is already required all the way for
    
building documentation.
    

    This is a variant of commit 628ceac6526724d35cb390cc1f88344f4ea22eb4
    
which was reverted due to out-of-tree build failure.

  • Why isn't my bash script working ?

    15 mai 2016, par JulianJ

    I’m trying to get this bash script to work but am at a loss. I have a text file that contains a list of frame numbers line by line. ffmpeg reports the error :

    Undefined constant or missing '(' in '$name)'

    The script

    #!/bin/bash
    
source text.txt
    
while read name
    
do
    
 ffmpeg -i result.mp4 -vf "setpts=N+1,select='eq(n,\$name)'" -vframes 1 frame-$i.jpg
    
done code>

  • Why is my bash script halting with ffmpeg ?

    16 mai 2016, par JulianJ

    I have a text file that contains frame numbers line by line and I am using a bash script and ffmpeg to cycle through each line and attempt to print out a thumbnail of each frame.

    Each time I run the bash script in my terminal it halts with an error having created the first thumbnail. It seems it is not given the thumbnail a unique name. What am I doing wrong ?

    My bash script :

    #!/bin/bash
    
source text.txt
    
while read name
    
do
    
ffmpeg -i result.mp4 -vf "setpts=N+1,select='eq(n,$name)'" -vframes 1 frames-$i.jpg
    
done code>

    The error :

    File 'frames-.jpg' already exists. Overwrite ? [y/N] Not overwriting - exiting
