• How to upload object to a bucket in Google Cloud Platform from Python script

  7 juillet 2016, par Bryan

  The goal of this script is to extract audio from a video file using ffmpeg and upload it into a bucket on Google Cloud Platform each time it is called. Eventually I will have to extract audio from a large list of videos, so ideally I would want my script to extract and subsequently upload it into the cloud.

  My confusion is how to use GCP API to upload my object into a bucket. Any advice would be greatly appreciated !

  import subprocess
  
  import sys
  
  import re 
  
  
  
  fullVideo = sys.argv[1]
  
  title = re.findall('^([^.]*).*', fullVideo)
  
  title = str(title[0])
  
  subprocess.call('ffmpeg -i ' + fullVideo + ' -vn -ab 128k ' + title + '.flac', shell = True)
  
  
  
  def upload_object(bucket, filename, readers, owners):
  
      service = create_service()
  
  
  
      # This is the request body as specified:
  
      # http://g.co/cloud/storage/docs/json_api/v1/objects/insert#request
  
      body = {
  
          'name': filename,
  
      }
  
  
  
      # If specified, create the access control objects and add them to the
  
      # request body
  
      if readers or owners:
  
          body['acl'] = []
  
  
  
      for r in readers:
  
          body['acl'].append({

              bucket=bucket, body=body,
  
              # You can also just set media_body=filename, but # for the sake of
  
              # demonstration, pass in the more generic file handle, which could
  
              # very well be a StringIO or similar.

• How convert video to mp4 before upload to Google Storage ?

  6 février 2018, par Sofiia Vynnytska

  Currently, I have an API which uploads files to Google Storage. If user uploads video it should be converted to mp4. I took a look at FFMEPG and Java wrapper around the FFmpeg , but I need to convert video directly from InputStream without writing into a disk. Is there any solution to convert InputStream into mp4 ?

• Auto install FFMPEG on Google Compute Engine (Debian Wheezy 7.8)

  1er octobre 2015, par DynamoBooster

  I have a Google Cloud Compute Engine project and want to auto-install FFMPEG on all the instances. I am using the node.js module https://github.com/fluent-ffmpeg/node-fluent-ffmpeg to watermark videos uploaded to the server and generate thumbnails. It’s working perfectly fine on my local machine that has ffmpeg installed. But how do I install/auto install ffmpeg on all virtual machine instances in the google cloud project ?
