Hammer - Simple Thumbnail Generation Service (for images and videos).

Dependencies

• Consul
• RabbitMQ
• mini-fstore
• ffmpeg (for generating video thumbnail)

Updates

• Since v0.0.5, hammer nolonger uses libvip (external dependency) to compress images. It now uses github.com/disintegration/gift instead, it might be slower and more resource intensive, but it's written purely in Go.
