Media
FFmpeg handles encoding and decoding on the host, with hardware paths for NVENC, QuickSync, AMF and VideoToolbox, and H.264, HEVC and AV1 where the hardware and the browser both agree.
Low latency audio in both directions, for the session sound and for voice in a room.
Transport
WebRTC
WebRTC for one to one sessions. ICE finds the shortest path, DTLS-SRTP encrypts it, and a TURN relay steps in only when the network refuses a direct route.
QUIC and Media over QUIC
QUIC with TLS 1.3 built in, carrying Media over QUIC. One publish, many subscribers, and no head of line blocking between them.
Why two transports
| When | Pick | Reason |
|---|---|---|
| One person driving | WebRTC | Shortest possible path, direct where the network allows |
| Several people watching | Media over QUIC | Fan out through a relay, so a slow viewer stalls only their own picture |
| LAN or VPN | Media over QUIC direct | No relay hop at all when the browser can reach the host |
Input
ViGEmBus presents a virtual Xbox or PlayStation controller to games and carries rumble back.
Alluno's own input driver delivers keyboard and mouse events at the device level, which is what raw input titles expect.
