• 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.

• Boto3 Video Upload 0 Bytes from Heroku

  14 juillet 2017, par genghiskhan

  I have a small Flask api that takes a video and an image, overlays the image on the video and uploads the result to Amazon S3. I am using ffmpeg to do the actual overlaying. Here is that code :

  command = "ffmpeg -i {0} -i {1} -filter_complex \"overlay=0:0\" {2}".format(background_name, overlay_name, output_name)
  
  subprocess.getoutput(command)

  Then I simply upload it via Boto3 :

  s3.upload_file(output_name, VIDEO_BUCKET_NAME, output_name)

  This code works fine when I run on localhost ; however, when I test in while deployed to Heroku, it always uploads a file with 0 bytes. I suspect that it may be a problem with Heroku’s transient filesystem, but the file is being used immediately after it is created.
