  • FFmpeg (Thumbnail from video) works in command line, but not in PHP script

    25 juin 2017, par Jun Kim

    I looked at the similar questions, and the solutions there do not work in my case. Anyone has any idea ? I am trying to capture a thumbnail from a given video file.

    Later, my goal is to capture a thumbnail from live streaming video file.

    Below is my current set up.

    Linux Ubuntu 16.04

    PHP version 7.0

    Nginx Version 1.10.3

    FFmpeg Version FFmpeg 2.8.11

    I installed FFmpeg through below commands in my Ubuntu server.

    apt-get update
    
apt-get install ffmpeg

    When I type the below command line in the terminal, it does the conversion fine.

    ffmpeg -i /etc/nginx/html/test.mp4 -ss 00:00:01 -vframes 1 -vf scale=240:120 /etc/nginx/html/Share/ffmpeg/thumbnails/test.png;

    In order to use it in php file, I confirmed the location of ffmpeg binaries by I typing in the terminal, which ffmpeg, and it returns /usr/bin/ffmpeg

    I also gave permission to the directory by using chmod 755 command line.

    Here is what I have in my ffmpeg.php file.
    I included the full path to my ffmpeg as you can see.

    <?php
    
header("Content-Type: text/html;charset=UTF-8");
    

    
$ffmpeg = "/usr/bin/ffmpeg";
    
$videoFile="/etc/nginx/html/test.mp4";
    
$thumbnail= "/etc/nginx/html/Share/ffmpeg/thumbnails/thumbnail1.jpg";
    

    
$cmd = "$ffmpeg -i $videoFile -ss 00:00:01 -vframes 1 -vf scale=240:120 $thumbnail 2>&1 &";
    

    
$output = shell_exec($cmd);
    
echo "<pre>".$output."</pre>";
    
?>

    This returns the message like below.

  • Sync 2 Audio Files [on hold]

    30 mars 2017, par Syed Armaan Hussain

    I have 2 audio (.wav) files recorded by two different persons.
    They are saying the same sentences but there is some differences in duration like the first audio is 10 sec long but other is 9 sec long. There are deifference in silences and lipsing.
    I want to sync these two audios . How can i achieve it . If anyone out there has already did research on it . Please share your experience. Or any SDK that can help me with this . I am using C# tried it with ffmpeg but didnt find any command for this.
