• How to Manage User Uploaded Content and Storage

  6 novembre 2014, par Ben

  I’m building an app in PHP (Laravel 4 framework) where a teacher in their account can create a digital lesson for a student. Digital lessons can contain the following content :

  • Text (text from form, .doc, .txt, .pdf, etc.)
  • Images (.gif, .png, .jpg etc.)
  • Video (.avi, .mov, .mp4, etc.)
  • Audio (.mp3, etc.)

  Raw text entered from forms can obviously be stored in the DB against the lesson_id. All the other content formats will need to be stored somewhere, where I can manage and read the files, as well as keep track of the teachers storage total as I plan to bill for storage thresholds at 5GB, 10GB etc.

  On the create a lesson page, content files need to be uploaded as lesson attachments before the lesson is saved, so a teacher can visually see all the lessons content, and then hit save to create the lesson instantly.

  Here’s what I’ve come up with :

  1. Upload all lesson file attachments to AWS S3 to the teachers dedicated bucket, before the lesson is created. Add the teachers ID and date time to each filename.

  2. Force all uploaded video / audio files to be converted to .mp4, .mp3, etc. if they are not in an iDevice friendly format or they exceed a file size limit. Use FFmpeg to do this.

  3. When the lesson is saved and created, record the S3 file URL’s against the lesson ID in the DB.

  4. If the lesson has not been created after a specific period of time, run a cron job to check for uploaded S3 files with no lesson and delete them.

  I am unsure what is the best way to solve this problem as user uploaded content management is really new to me.

  What do you think of this approach ? Can you recommend an improved or better way to solve this problem ?

• How can I upload videos and convert it async in Laravel ?

  19 novembre 2016, par bretanac93

  the thing is just like my title says, I am already uploading videos to the server, store their path in the db, and save them to the storage using the Storage facade, the videos have an average weight of 700MB or so, and they are for watching on the own website I am building, I’m using VideoJS to show them, but I need to convert them due to the incompatibility with different browsers, I already know that FFMPEG done this painless, but I want to know how to make it async, just like the Youtube upload video tool. The videos are uploaded from the admin dashboard only, so, there will be only one person uploading videos. Thanks for the time.
