  • 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.
    The code of this (...)

  • converting video with php and ffmpeg

    6 mai 2015, par Ford

    i am trying a simple test to learn how to convert videos with ffmpeg via PHP as they are uploaded to my site (to .mp4).
    however am i missing something, as my simple test is doing nothing....

    code (simplified)

    $videoFile = '/home/xxx/public_html/dev/videos/1746/sample.avi';
    
exec("ffmpeg -i $videoFile -vcodec h264 -acodec aac -strict -2 /home/xxx/public_html/dev/videos/1746/test.mp4");

    i have also trired

    system("ffmpeg -i $videoFile -vcodec h264 -acodec aac -strict -2 /home/xxx/public_html/dev/videos/1746/test.mp4");

    and

    shell_exec("ffmpeg -i $videoFile -vcodec h264 -acodec aac -strict -2 /home/xxx/public_html/dev/videos/1746/test.mp4");

    Also if i try

    echo exec('ffmpeg -formats');

    i get no output

    none of the above convertion tests work and no test.mp4 file is created.
    i have error reporting turned on yet get no errors.

    any advice would be welcomed please

  • issue with ffmpeg config

    4 janvier 2015, par ali raha

    a ffmpeg was installed in my server but it no support some liberary like libvpx
    (centos 6.5)
    I couldn’t uninstall it but I install I new one with this tutorial :
    http://wiki.razuna.com/display/ecp/FFMpeg+Installation+on+CentOS+and+RedHat#FFMpegInstallationonCentOSandRedHat-InstallLibvpx

    (all configs in ffmpeg seems install correctly)

    PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig"
    
export PKG_CONFIG_PATH
    
./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" \ 
    
--extra-libs=-ldl --enable-version3 --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvpx --enable-libfaac \
    
--enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libvo-aacenc --enable-libxvid --disable-ffplay \
    
--enable-gpl --enable-postproc --enable-nonfree --enable-avfilter --enable-pthreads

    So I want to test it :

    I try test it with :

     #ffmpeg

    result :

    enter image description here

    It seems related with older ffmpeg that was install.
    no change and no lib add !

  • FFMPEG - Drawtext or drawbox or overlay on single frame

    2 novembre 2011, par waxical

    I'm using the avfilters on FFMPEG to drawtext and drawbox. Two of the most poorly documented functions known to man.

    I'm struggling to work out how and if I can use this on a single frame. I.e. appear drawtext on frame 22.

    Current command :-

    ffmpeg -i /home/vtest/test.wmv -y -b 800000 -f flv -vcodec libx264 -vpre default -s 768x432 -g 250 -vf drawtext="fontfile=/home/Cyberbit.ttf:fontsize=24:text=testical:fontcolor=green:x=100:y=200" -qscale 8 -acodec libfaac -sn -vstats  /home/testout.flv

    Two elements mention here in the documentation are n and t - however I only seem to be able to use them in x and y. Not in text or even as other parameters.

    Any help or ffmpeg guidance would be gratefully received.
