  • Store converted video in a buffer to transfer to S3

    24 mai 2012, par Chris

    I have a system set up to upload an image, take that temporarily uploaded file, convert it to a resized jpeg, read the buffer of that conversion and send the buffer to amazon S3 for storage as an image. It works wonderfully because no permanent file is stored on the my server, everything is on S3.

    Now I am attempting to add this same functionality but with video. The process goes through, but the resulting files stored on Amazons S3 servers are 1.5kb a piece, instead of multimb videos.

    My code is as follows :

    public function transfer($method, $file, $bucketName, $filename, $contentType){
    
    switch($method){
    
        case 'file':
    
            if($this->s3->putObject($this->s3->inputFile($file, false), $bucketName, $filename, S3::ACL_PUBLIC_READ, array(), $contentType))
    
                return true;
    
            else
    
                return false;
    
            break;
    
        case 'string':
    
            if ($this->s3->putObject($file, $bucketName, $filename, S3::ACL_PUBLIC_READ, array(), $contentType))
    
                return true;
    
            else
    
                return false;
    
            break;
    
        case 'resource':
    
            if($this->s3->putObject($this->s3->inputResource(fopen($file, 'rb'), filesize($file)), $bucketName, $filename, S3::ACL_PUBLIC_READ, array(), $contentType))
    
                return true;
    
            else
    
                return false;
    
            break;
    
    }
    
    return false;
    
}   
    

    

    
/**
    
*   AmazonS3Handler - convert()
    
*/
    

    
public function convert($file, $type)
    
{
    
         $ffmpeg = "/usr/bin/ffmpeg";
    
    $cmd['webm'] = $ffmpeg. " -i ". $file ." -vcodec libvpx -acodec libvorbis -ac 2 -f webm -g 30 2>&1";
    
    $cmd['ogv'] = $ffmpeg. " -i ". $file ." -vcodec libtheora -acodec libvorbis -ac 2 2>&1";
    
    $cmd['mp4'] = $ffmpeg. " -i ". $file ." -vcodec libx264 -acodec libfaac -ac 2 2>&1";
    
    $cmd['jpg'] = $ffmpeg. " -i ". $file ." -vframes 30";
    

    
    ob_start();
    
    passthru($cmd[$type]);
    
    $fileContents = ob_get_contents();
    
    ob_end_clean();
    
    return $fileContents;
    
}

    From my understanding, passthru should return raw output which could be picked up by the output buffer.

    Am I doing something wrong ? Is there a better way to convert a video on my servers but keep the data on S3 ?

    Thanks !

    EDIT : I've boiled it down to the executing of the command. FFMPEG wasn't being located, so I changed the path to "/usr/bin/ffmpeg", no more error 127, now when I run exec() (not passthru) I get error 1

    EDIT2 : Here is the output of running the script :

  • Create stopmotion video with ffmpeg - error while rendering

    30 mai 2012, par Niklas

    I'm currently creating a stopmotion video with the help of ffmpeg and some scripts I've made. Although in the last clip I attempted to render I had a couple of frames which I've edited. The method I'm using has worked before so I'm certain that it has to do with GIMP changing something with the files. I work with .png-images. This is the command and the output I get :

    ffmpeg -sameq -f image2 -r 7 -i "$src_dir/frame-%06d.png" -r 25 "$dest_dir/$file_name.avi"

  • Segmenting an audio stream or audio only file

    15 janvier 2013, par Luuk D. Jansen

    There is need for an audio only link for HTTP-live streaming. I now use the segmenter in FFMPEG for the video, and that works great. However, when giving an audio-file the segmenter does not seem to work, just creates one segment.

    The call to FFMPEG for the segmentation is :

    ffmpeg -i data/media/1/2/encoded.mp3 -y -c copy -flags global_header
    -map 0 -f segment -segment_time 10 -segment_list data/media/1/2/fileList.txt -segment_format libmp3lame
    data/media/1/2/segment_%05d.mp3

    I did put as the -segment_format 'libmp3lame' in, but it doesn't seem to make a difference.

    The first step is the encoding, this is the bedbug output :
