commucat-media

Media primitives shared by the CommuCat server and operational tools.

Features

• Safe wrappers for audiopus and env-libvpx to encode/decode Opus and VP8/VP9 frames.
• CallMediaPipeline (feature pipeline) – synchronous Opus encode/decode loop with frame duration control for smoke testing.
• voice module – encoders/decoders, signal level helpers, integration with commucat-media-types.
• video module – RAW I420 → VP8/VP9 encoding, optional AV1/H.264 support through the codec-av1 and codec-h264 features.
• capture (feature audio-io) – PCM capture via cpal producing i16 frames.

Limitations

• Adaptive bitrate, forward error correction and SVC are only partially implemented and not wired into end-to-end flows yet.
• AV1/H.264 rely on native libraries (rav1e, openh264); enabling the features pulls the corresponding build dependencies.
• No GPU/accelerated codec bindings are provided.
