• Execute ffmpeg in AWS ec2 instance windows

  15 janvier 2016, par Napster

  Im trying to execute ffmpeg command on amazon’s windows ec2 instance using elastic beanstalk.
  I intend to merge multiple videos into a single video using a .net application.

  I cant see the file being created in the folder, so cant confirm if ffmpeg is working. The merging is working perfectly on local deployment and i can view the merged video.
  I have configured my deployment for the required permission of file creation rights (.ebextensions) and it is working.

  Im not sure what i need to do to allow execution of ffmpeg command, and im stuck here. Ive been through the forum and found similar links related to linux but not windows.

  Being a newbie im really not sure how to proceed.
  Are there any permission/steps i need to perform to allow ffmpeg command to execute on ec2 instance. If any ? please share.

• Rails Thumbnails for videos being uploaded to S3

  20 octobre 2015, par Dani

  I have a rails application where I need to upload videos to an amazon s3 bucket alongwith their thumbnails. I am using ffmpeg to generate thumbnails and I am using carrierwave to handle video uploads. Here is my video uploader class

   class VideoUploader < CarrierWave::Uploader::Base
  
    include CarrierWave::Video
  
    storage :fog
  
    def store_dir
  
       "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  
    end
  
    def extension_white_list
  
      %w(mp4 flv)
  
    end
  
  end

  The video uploads fine and the column for video url is set in videos table but I want to generate thumbnail and upload it as well. I know I have to use ffmpeg here but don’t exactly know how to do it.

  Any help will be appreciated.

• Encoding videos locally or through a third party ?

  7 septembre 2015, par JordanDevelop

  We’re in the process on building a view uploading and sharing community right now and we’re currently developing with idea of using a third-party like Zencoder, but what makes Zencoder a better option ?

  I’m sorry if i butcher up what is involved with supporting a local encoding system, so I’ll try to be vague. We plan on releasing with AWS, so why not setup an instance running ffmpeg ? I understand it’s a lot more then simply that, but if is it that difficult to find someone who can put together an instance for encoding ?

  Am I right to assume most third party encoding services seem very unrealistic, price wise, for a web application who specifically focus on encoding large amounts of media ? I did notice Amazon offers an encoding features and would definitely feel more comfortable using them, but even that seems seems redundant.

  I completely understand the cost behind encoding is very real, but I just can’t understand why third-party encoders are so widely accepted.
