  • AFTER PHP-FFMpeg not converting (error with ffmpeg)

    15 août 2016, par Magurean Dan Sergiu

    I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

    root@host [/opt/ffmpeg]# ffmpeg

    But when I try to convert a video file with a php script it throws me a very long error.
    PHP Code :

    <?PHP
    
include($_SERVER['DOCUMENT_ROOT']."/vendors/install/vendor/autoload.php");
    
$ffmpeg = FFMpeg\FFMpeg::create();
    
$video = $ffmpeg->open($_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.wmv');
    
$video
    
       ->filters()
    
       ->synchronize();
    
$format = new FFMpeg\Format\Video\X264();
    
$format->on('progress', function ($video, $format, $percentage) {
    
    echo "$percentage % transcoded";});
    
$video
    
      ->save($format,$_SERVER['DOCUMENT_ROOT'].'/resources/uploads/96048/ffd3c5e349fa5745159deef163b5c253.mp4');
    
?>

    Error displayed :

    Then I have took the basic code displayed upwards and ran it directly through ssh.

Unknown encoder 'libx264'

    My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

    After a few modifications

    I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.

  • avformat/mov : Only read the primary item for AVIF

    28 juin 2022, par Vignesh Venkatasubramanian
    avformat/mov : Only read the primary item for AVIF

    Update the still AVIF parser to only read the primary item. With this
    
patch, AVIF still images with exif/icc/alpha channel will no longer
    
fail to parse.
    

    For example, this patch enables parsing of files in :
    
https://github.com/AOMediaCodec/av1-avif/tree/master/testFiles/Microsoft
    

    Adding two fate tests :
    
1) demuxing of still image with 1 item - this test will pass regardless
    
   of this patch.
    
2) demuxing of still image with 2 items - this test will fail without
    
   this patch and will pass with patch applied.
    

    Partially fixes trac ticket #7621
