OpenH264 is a BSD-licensed C++ library implementing H.264/AVC video encoding and decoding, suitable for real-time applications like WebRTC. It supports constrained baseline profile up to Level 5.2, temporal scalability, simulcast, and runs across many platforms and architectures.
Use cases
- encode video to h264 in real time
- decode h264 streams in a webrtc application
- embed an open-source h264 codec in a mobile app
- transcode video with rate control and adaptive quantization
- add temporal scalability to a video conferencing system
When to choose
- you need a permissively licensed (BSD) H.264 codec
- you are building real-time communication like WebRTC
- you need cross-platform support including mobile (Android/iOS)
- you need features like LTR frames, simulcast, or temporal scalability
When to avoid
- you need advanced profiles like High Profile or HEVC/H.265
- you need hardware-accelerated encoding via GPU APIs
- you need AVX-optimized assembly (not yet supported)
- you prefer a full multimedia framework rather than a codec library
