Since we are all plugging our competing projects, here's mine: https://github.com/alexstaubo/tootsie https://github.com/alexstaubo/tootsie * Written in Ruby with Sinatra. * Supports both SQS and AMQP (eg., RabbitMQ). * Simple REST interface for submitting jobs. * Can get/put both HTTP and S3 URLs. * Image support: Scaling, cropping, format conversion, EXIF/IPTC stripping. Uses ImageMagick. * Audio/video support: Scaling, format conversion, thumbnail extraction from videos. Uses ffmpeg. * Has a helper component that provides live upload progress, jQuery uploader, etc.: https://github.com/bengler/tiramisu https://github.com/bengler/tiramisu Tootsie is intended as a generic conversion/transcoding framework, so it does more than just thumbnail images. Oh, and it has been run in production for a long time.
