  • FFMPEG running in Command Line but not PHP

    17 avril 2013, par Freeman

    I am using ffmpeg build for windows to make video thumbnails . The command works well in command line but not from PHP exec method. am using PHP 5.2.11

    Here is the command.

    "E:/Documents and Settings/x/WINDOWS/ffmpeg" -itsoffset -4 -v "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/videogal/c08c3d20eeb9083ed033577bd154cba6.flv" -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/gallery/8ff43b72b932d2a34e7a6733672ad4d6.jpg" 2>&1

    Can somebody help. I checked the permissions they seem fine. GD is installed.

    The error msg is 'E:/Documents' is not recognized as an internal or external command, operable program or batch file

    Am using forward slashes in my paths except when escaping double quotes

    The PHP function

    function ExtractThumb($in, $out)
    
{$path=dbconf::FFMPEG_PATH;
    
    $thumb_stdout;
    
    $errors;
    
    $retval = 0;
    
 echo $in;
    
    // Delete the file if it already exists
    
    if (file_exists($out)) { unlink($out); }
    

    
    // Use ffmpeg to generate a thumbnail from the movie
    
    $cmd = "$path -itsoffset -4 -i $in -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 $out 2>&1";
    
   echo $cmd;
    

    
   exec($cmd, $thumb_stdout, $retval);
    

    
    // Queue up the error for processing
    
    if ($retval != 0) { $errors[] = "FFMPEG thumbnail generation failed"; }
    

    
    if (!empty($thumb_stdout))
    
    {
    
        foreach ($thumb_stdout as $line)
    
        {
    
            echo $line . "\n";
    
        }
    
    }
    

    
    if (!empty($errors))
    
    {
    
        foreach ($errors as $error)
    
        {
    
            echo $error . "\n";
    
        }
    
    }
    
}

    funny enough if I run without the $in and $out absolute path this is what I get

  • ffmpeg to convert mov to flv

    27 octobre 2014, par jeet

    I’m trying to convert a mov video to flv, but keep getting these errors below.
    There are 2 commands I used, both are below.

    ffmpeg -y -i video.mov -deinterlace -acodec copy -r 25 -qmin 3 -qmax 6 video.flv

    Second command :

    ffmpeg -y -i video.mov -deinterlace -ar 44100 -r 25 -qmin 3 -qmax 6 video.flv

    Audio resampler only works with 16 bits per sample, patch welcome.

Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input

    1 more thing please :
    If I use this newer version of ffmpeg to create a video with the below command, I get a video with a very hazy display.
    It’s like a few black dots on a blank screen :

    ffmpeg -i img%d.png -i audio.wav -acodec copy output.mov

    what could be the reason for this display ?
