Crate moq 

C FFI bindings for MoQ (Media over QUIC).

This library provides a C-compatible API for working with MoQ broadcasts, enabling real-time media delivery with low latency at scale.

The API is organized around several key concepts:

• Sessions: Network connections to MoQ servers
• Origins: Collections of broadcasts that can be published or consumed
• Broadcasts: Container for media tracks
• Tracks: Individual audio or video streams
• Frames: Individual media samples with timestamps

All functions return negative error codes on failure, or non-negative values on success. Most resources are managed through opaque integer handles that must be explicitly closed.
