Desktop or file streaming
X11 desktop capture encodes to H.264 via NVENC when available, falling back to libx264. Local H.264 files can be streamed with no re-encode.

Desktop streaming for Bigscreen VR on Linux, Windows, OSX & Android.
bsdrX is a portable C reimplementation of the PC-agent side of Bigscreen's Remote Desktop protocol. It is built to cast a Linux desktop — or a local H.264 video file — into a Bigscreen VR headset, with input, audio, pairing, and experimental voice control.
The archive link is intentionally live now; upload bsdrX.zip into this document root when ready. Windows, macOS, and Android builds are planned but not published yet.
$ ./build/bsdr_agent -v
discovery: UDP 45000/45001 · control: HTTP 45678
transport: DTLS-SRTP over UDP 45002 · no ICE
video: X11 → NVENC/libx264 → H.264 RTP/SRTP
audio: PulseAudio ↔ Opus · input: uinput

A remote desktop agent for the headset era.
bsdrX focuses on the PC-agent side: discovery, pairing, media transport, headset input, and local control UI — with Linux as the first-class target.
🎧
Audio both ways
System audio is routed to the headset with Opus, while headset microphone audio can become a virtual microphone on the host.
🎮
Headset input back to PC
Mouse, keyboard, wheel, buttons, and XInput gamepad frames are decoded from the DataChannel and injected with native OS APIs.
🕹️
Local control UI
A slim web panel on 127.0.0.1:8088 handles login status, Quest selection, source selection, resolution, bitrate, and restarts.
🗣️
Voice computer control
An experimental in-VR mic balloon can transcribe commands and let an OpenAI-compatible LLM type, click, scroll, and open apps.
Downloads
Linux alpha is the initial distribution target. Windows, macOS, and Android builds are on the roadmap.
