  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.

  • FFMPEG works on Console but doesn't work in PHP script on Ubuntu

    16 novembre 2016, par Victor Ferreira

    I have this aplication where I need to convert video files to MP4 and then compress it. I’m trying to use FFMPEG to get this to work. Tried the command lines in the console and it works great

    Converting

    ffmpeg -i teste.avi teste.mp4

    Compressing

    ffmpeg -i teste.mp4 -acodec mp2 teste.mp4

    But when I do the same within a PHP script, it starts yelling that something called GLIBCXX is not installed. This is the error :

    ffmpeg: /opt/lampp/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib/i386-linux-gnu/libjack.so.0)
    
ffmpeg: /opt/lampp/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/lib/i386-linux-gnu/libjack.so.0)

ffmpeg: /opt/lampp/lib/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /usr/lib/i386-linux-gnu/libopencv_core.so.2.4)

    This is my script

    $r = shell_exec("ffmpeg -i $file_path $output_path 2>&1"); //convert
    
$r = shell_exec("ffmpeg -i $file_path -acodec mp2 $file_path 2>&1"); //compress

    I’m running the script on Ubuntu

    @edit
    I can run, for example, shell_exec(’ls’)

  • FFMPEG converts HEVC with Alpha mov to PNG sequence not work well

    22 juillet 2023, par topfortune

    I have a mov file with HEVC with Alpha codec on Mac. The mov file has no background color, but have some foreground contents in it. I want to use FFMPEG to grab some PNG pictures from it. Following is the command line I used to grab the first image from the video.

    


    ffmpeg -i hevc-alpha-video.mov -r 1 -pix_fmt rgba -frames:v 1 out.png

    


    I can get the output PNG picture. But it has black background color. What I want is the transparent background PNG picture.

    


    Do you have any idea to handle this ? Thanks.
