  • Install ffmpeg on elastic beanstalk using ebextensions config

    27 mai 2023, par user3581244

    I'm attempting to install an up to date version of ffmpeg on an elastic beanstalk instance on amazon servers. I've created my config file and added these container_commands :

    



        container_commands:
        01-ffmpeg:
            command: wget -O/usr/local/bin/ffmpeg http://ffmpeg.gusari.org/static/64bit/ffmpeg.static.64bit.2014-03-05.tar.gz
            leader_only: false
        02-ffmpeg:
            command: tar -xzf /usr/local/bin/ffmpeg
            leader_only: false
        03-ffmpeg:
            command: ln -s /usr/local/bin/ffmpeg /usr/bin/ffmpeg
            leader_only: false


    



    Command 01 and 03 seems to work perfectly but 02 doesn't seem to work so ffmpeg doesn't unzip. Any ideas what the issue might be ?

    



    Thanks,
Helen

    


  • passing additional values to s3 event notification for lambda consumption

    8 septembre 2017, par user1790300

    I have to write code in react-native that allows a user to upload videos to amazon s3 to be transcoded for consumption by various devices. For the processing after the upload occurs ; I am reviewing two approaches :

    1) I can use Lambda with ffmpeg to handle the transcoding immediately after the uploading occurs (my fear here would be the amount of time required to transcode the videos and the effect on pricing if it takes a considerable amount of time).

    2) I can have s3 pass an sns message to a rest api after the created event occurs and the rest api generate a rabbitmq message that will be processed by worker that will perform the transcoding using ffmpeg.

    Option 1) seems to be the preferable option based on a completion time perspective. How concerned should I be with using 1) considering how long video transcoding might take as opposed to option 2) ?

    Also, regardless, I need a way to pass additional parameters to lambda or along the sns messaging that would allow me to somehow associate the user who uploaded the video with their account. Is there a way to pass additional text-based values to s3 to pass along to lambda or along sns when the upload completes, as a caveat I plan to upload the video directly to s3 using the rest layer(found this answer here : http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html#RESTObjectPUT-responses-examples) ?

  • PHP : Convert file with FFMPEG and upload to S3 using shell_exec() and aws cli tools

    18 septembre 2017, par andreaem

    I need a script that handle the upload of a video file from dropzone.js, convert to m4v then generate 5 thumbnails using the name of file appending -(number) to each jpg file (eg : file-1.jpg, file-2.jpg, file-3.jpgetc) and finally upload to s3 using shell_script (or maybe if there is a better way to do this).

    Recap

    1. Upload file in a temp dir
    2. Convert file to .m4v
    3. Generate 5 thumbnails from video
    4. Upload the converted video to Amazon S3
    5. Delete local video file

    Here is my code, at the moment I don’t know where the file goes and nothing seems to be uploaded to Amazon S3 (doing the upload in command-line works, so the credentials are ok).

    Dropzone.js

    $("#dZUpload").dropzone({
        url: "/ajax/admin/admin.acceptVideo.php",
        maxFilesize: 200,
        renameFile: new Date,
        acceptedFiles: "video/*",
        addRemoveLinks: true,
        success: function (file, response) {
             var imgName = response;                              file.previewElement.classList.add("dz-success");
             console.log("Successfully uploaded :" + imgName);
             $('#form_video').val(file);
        },
        error: function (file, response) {file.previewElement.classList.add("dz-error");
        }
    }).autoDiscover = false;
       Dropzone.prototype.defaultOptions.dictRemoveFile = "Rimuovi file";
       Dropzone.on("addedfile", function(file) {
           var cancelLink = Dropzone.createElement('<a>Cancel upload</a>');
        file.previewElement.appendChild(cancelLink);
        cancelLink.addEventListener("click", function(e) {
        e.preventDefault();
        myDropzone.cancelUpload(file);
    });
    });

    PHP

    $target_dir = "/var/www/html/example.com/web/temp/";
    $target_file = $target_dir . basename($_FILES["file"]["name"]);
    $uploadOk = 1;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
    // Check if image file is a actual image or fake image
    if(isset($_POST["submit"])) {
       $check = getimagesize($_FILES["file"]["tmp_name"]);
       if($check !== false) {
           echo "File is a video - " . $check["mime"] . ".";
           $uploadOk = 1;
       } else {
           echo "File is not an image.";
           $uploadOk = 0;
       }
    }
    // Check if file already exists
    if (file_exists($target_file)) {
       echo "Sorry, file already exists.";
       $uploadOk = 0;
    }
    // Check file size
    if ($_FILES["fileToUpload"]["size"] > 200000000) {
       echo "Sorry, your file is too large.";
       $uploadOk = 0;
    }
    // Allow certain file formats
    if($imageFileType != "mp4" &amp;&amp; $imageFileType != "mov" &amp;&amp; $imageFileType != "avi" &amp;&amp; $imageFileType != "m4v" ) {
       echo "Sorry, only MP4 MOV AVI M4V files are allowed.";
       $uploadOk = 0;
    }
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
       echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
    } else {
       if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {
           S3Up(VideoConvert(basename( $_FILES["file"]["name"]),random_int('1','9999')));
           echo "The file ". basename( $_FILES["file"]["name"]). " has been uploaded.";
       } else {
           echo "Sorry, there was an error uploading your file.";
       }
    }

    function VideoConvert($video, $id) {
       shell_exec('ffmpeg -i ' . $video . ' /var/www/html/example.com/web/temp/' . $id . '.m4v');
       for ($i=0;$i &lt;= 5;$i++) {
           shell_exec('ffmpeg -i ' . $video .' -vf "select=gte(n\,' . $i .'00)" -vframes 1 ' .$id . '-' . $i. '.jpg');
       }

       return '/var/www/html/example.com/web/temp/' . $id . '.m4v';
    }

    function S3Up($video) {
       shell_exec('aws s3 cp ' . $video .' s3://example-video/ --grants read=uri=http://acs.amazonaws.com/groups/global/AllUsers');
       sleep(1);
       //shell_exec('rm '. $video);
    }

    Here is my error.log line relating to s3 upload :

    error.log

    example.mp4: No such file or directory
    Traceback (most recent call last):
     File "/usr/local/bin/aws", line 19, in <module>
       import awscli.clidriver
     File "/usr/local/lib/python2.7/dist-packages/awscli/clidriver.py", line 17, in <module>
       import botocore.session

       from dateutil.parser import parse
    ImportError: No module named dateutil.parser
    </module></module></module></module>

    How can I improve this ? I’ve tried using aws php api but got some problems with credentials, cli tools don’t have.

    Behavior

    At the moment dropzone.js stop uploading at 50% if I put a file of 8 MB, php maxUploadSize directive is set to 201M, php upload temp folder is inside the site root directory and permissions set to 7777. File where uploaded if I put a smallest file of 200Kb but don’t convert and make a 0 byte file.
