RoR: using paperclip for video upload and transcoder with elastic transcoder

I was wondering if anyone can help me with this issue.

I need help to find a way to make paperclip work with elastic transcoder.

I need to be able to save an uploaded video in S3 Amazon bucket using paperclip and then transcode the uploaded video into 3 different format and save them back in the same bucket.

The issue is can I get all done together?

This issue has been solved by using a gem called 'elastic_transcoder'

Here is a sample of what I have done using elastic_transcoder

  • First get the url of the video you want to transcode excluding the AWS domain name and bucket name.

    url = self.paperclip_video.url.split('/').pop
    url = url.drop(3).join('/')

    you got the idea the above code varies depending on the url you get you just need the path as I said before excluding the AWS domain name and bucket name.

  • Then get the path to the original video
    input_url = url + '/' + self.paperclip_video_file_name

  • Then get the filename excluding the extension to user to generate the output url for the transcoded video

    file_name = File.basename(self.paperclip_video_file_name, File.extname(self.paperclip_video_file_name))

  • Then create the output path

    output_url = url + '/mp4_' + file_name + '.mp4'

    For simplicity I am transcoding to one type which is mp4

  • Create a new elastic transcoding pipline

    pipeline = ElasticTranscoder::Pipeline.new

    please note that you need to set first the pipeline on you AWS account moreover you need to set your preset for mp4 conversion on your AWS account.

  • Initialize your pipline object by passing your pipeline_id which you obtained from AWS

    pipeline_front.pipeline '***************'

  • create a new Jobs object to pass you transcoding jobs to

    jobs = ElasticTranscoder::Jobs.new

  • create new Job

    jobs.create_job input_url, output_url, "**your pipeline_id**", "your preset_id", "#{url}/web_thumbnail-{count}"

This will do the job and you can get the video transcoded.
