  • Amazon Elastic Transcoder vs FFMPEG [closed]

    7 juillet 2017, par KiranD

    I’m developing a website (php based) and there is a provision to upload videos in different formats. I’m using HTML5 player for the front end presentation. So, as the ideal format that is supported by most of the browsers is mp4, I tried using ffmpeg and it works fine.

    I would like to know which transcoder (Amazon Elastic Transcoder or FFMPEG) would be best for handling conversions parallely when there is a huge traffic.

    There could me approximately thousands of users watching the videos and may be hundreds uploading the videos at the same time. I’m using Amazon EC2 for deployment and the traffic is mostly spiky (not flat).

    I’m not sure about the acceptable speed. But, I need the one which can transcode the videos much faster.

  • Best practices for developing scalable video transcoding server on Amazon Web Services ? [closed]

    5 février, par undefined

    What do people think are the most important issues when developing an application that is going to allow users to upload video and images to a server and have them transcoded by FFMPEG and stored in amazon S3 ? I have a couple of options ;

    


      

    1. install FFMPEG on the same server that handles file uploads, when a video is uploaded and stored on EC2 instance, call FFMPEG to convert it then when done, write the file to S3 bucket and dispose of the original.

      2. 


    


    How scalable is this ? What happens when many users upload at the same time ? How do I manage multiple processes at once ? How do I know when to start another instance and load balance this configuration ?

    


      

    1. Have one server for processing uploads (updating database, renaming files etc) and one server for doing transcoding. Again what is the best way to manage multiple processes ? should I be looking at Amazon SQS for this ? Can I tell the transcoding server to get the file from the upload server or should I copy the file to the transcoding server ? Should I just store all files on S3 and SQS can read from there. I am trying to have as little traffic as possible.

      2. 


    


    I am running a linux box as the upload server and have FFMPEG running on this.

    


  • Php - Get video duration from a file hosted on amazon S3 server

    8 mai 2017, par Michael Lee

    I am developing back-end API with php to get the duration from a video file hosted on amazon S3. The API server is hosted on amazon EC2 and the video file is uploaded on amazon S3. The problem is when I request to API server, it has to response the information of the video file hosted on amazon S3 such as duration, file size, resolution etc. At least, it must response the video. I’ve followed codes by using ffmpeg such as below, but it’s not working.

    <?php
    
$file = 'https://videoapptest-bucket.s3.amazonaws.com/video/10/44__55_f03876434e48d5fed7d6982b0cf578de_u_00000.ts';
    
$result = shell_exec('ffmpeg -i ' . escapeshellcmd($file) . ' 2>&1');
    
preg_match('/(?<=Duration: )(\d{2}:\d{2}:\d{2})\.\d{2}/', $result, $match);
    
print_r($match);
    
?>

    How can I get the video duration from a file hosted on amazon s3 with ffmpeg or another tool ?
