Alfalfa is a purely functional VP8 video encoder and decoder written in C++ in explicit state-passing style, developed at Stanford. It underpins the ExCamera and Salsify systems and includes Salsify sender/receiver programs for low-latency video transmission.
Use cases
- encode video to VP8 in a purely functional state-passing style
- decode VP8 video frames
- run low-latency interactive video streaming with Salsify
- build serverless video processing pipelines like ExCamera
- research on functional video codecs and stateless computation
When to choose
- you need a stateless or functional-style VP8 codec for distributed or serverless video processing
- you are reproducing or extending ExCamera or Salsify research
- you want fine-grained control over per-frame encoding state
When to avoid
- you need a production-grade, feature-complete VP8 codec (use libvpx instead)
- you need hardware-accelerated encoding
- you need a permissively licensed project without GPL components
