### Did you look at Arcas for libwebrtc bindings? ### Did you look at [Arcas](https://github.com/arcas-io/libwebrtc) for libwebrtc bindings?
Yes. Our build system is inspired by LBL's work! Given that some of our logic (e.g. hardware decoder code) is in C++ and that we may need to bridge more/different things than Arcas, we decided it was better to have our own bindings for full control.

### Did you consider using [webrtc.rs](https://webrtc.rs/) instead of libwebrtc?
Yes! As webrtc.rs matures, we'll eventually migrate to a pure Rust stack. For now, we chose libwebrtc for a few reasons:
- Chrome's adoption and usage means libwebrtc is thoroughly battle-tested.
- webrtc.rs is ported from Pion (which [our SFU](https://github.com/livekit/livekit) is built on) and a better fit for server-side use.
- libwebrtc currently supports more features like encoding/decoding and includes platform-specific code for dealing with media devices.
