  • Is there a way to use ffmpeg to determine the encoding of a file before transcoding ?

    8 février 2016, par Bill Noble

    I am planning to use ffmpeg to ensure all video files uploaded to my website are encoded as mp4 h264.

    Rather than automatically processing every file I would like to minimise the processing overhead by only processing those files that are not already mp4 h264. Is there an easy way to do this either with ffmpeg or with another command line utility ?

  • How can I determine video rotation/orientation in PHP/FFMPEG/PhoneGap ?

    14 juin 2014, par SomethingOn

    Once I upload videos to my server I’m creating a screencap using FFMPEG. Problem is, if the user takes a video in portrait mode the screencap is rotated 90º. The ridiculous things is that PhoneGap and FFMEG-php and FFMPEG don’t seem to offer a mechanism for reading the video rotation/orientation value.

    I found another library called mediainfo that will provide the info, but not in an easy to read/digest manner and I’m trying to avoid having to use another library.

    Am I wrong about PhoneGap/FFMPEG ? Is there a direct way to determine video orienation ?

    Here’s my solution as a PHP function :

    function get_video_orientation($video_path) {
    
    $cmd = FFMPEG_PATH . "ffprobe " . $video_path . " -show_streams 2>/dev/null";
    
    $result = shell_exec($cmd);
    

    
    $orientation = 0;
    
    if(strpos($result, 'TAG:rotate') !== FALSE) {
    
        $result = explode("\n", $result);
    
        foreach($result as $line) {
    
            if(strpos($line, 'TAG:rotate') !== FALSE) {
    
                $stream_info = explode("=", $line);
    
                $orientation = $stream_info[1];
    
            }
    
        }
    
    }
    

    
    return $orientation;
    
}
