• 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.

• How to build a daemon to encode video files on S3 ?

  4 avril 2013, par Yuval Cohen

  I am interested in running a daemon to go over user uploaded video files and encode them in an optimal format (and add some watermarks).

  I was considering services such as Zencoder, Encoding.com, Amazon's encoding service but some lack overlaying capabilities and some are just too expensive for our (big) volumes.

  I want to build a daemon that encodes videos that are located on S3 once users upload them.

  The solution I thought of would be Python Heroku servers using Celery for a task queue to keep track of the encoded files and ffmpeg to do the actual work. However, I ran into troubles compiling ffmpeg for Heroku (with libass support, so the basic ffmpeg bins aren't enough).

  What approach/technology stack would you consider for this mini-project ?

  Thanks !

• How do I limit resources for ffmpeg, called from a python-script, running in a docker container ?

  26 juillet 2019, par wotanii

  I deployed a service, that periodically does video encoding on my server ; And every time it does, all other services slow down significantly. The encoding is hidden under multiple layers of abstraction. Limiting any of those layers would be fine. (e.g. limiting the docker-container would work just as well as limiting the ffmpeg-sub process.)

  My Stack :

  1. VPS (ubuntu:zesty)
  2. docker-compose
  3. docker-container (ubuntu:zesty)
  4. python
  5. ffmpeg (via subprocess.check_call() in python)

  What I want to limit :

  • CPU : single core
  • RAM : max 2 GB
  • HDD : max 4 GB

  It would be possible to recompile ffmpeg if needed.

  What would be the place to put limits in this stack ?
