xrm-streamer server grows here
Components
- server: Running directly on target device with OpenXR runtime. Receives layers and sound from clients and renders it. Contains all GUI settings
- streamer client: Driver or library, implementing openxr/openvr, receives tracking and streams video. There might be multiple client implementations (monado driver, monado in-process compositor, steamvr driver, OpenComposite driver)
- audio client: connects alsa/jack/pulseaudio to server with udp streams
- reconstructor/decomposer: stream encoding/decoding using Haar wavelet transform and video codec
Status
Server:
- TCP listener
- Receiving projection stream
- Connection/tracking with single client
- Very dumb audio streaming (does not use protocol)
- GUI prototype rendering (basic monitoring only, configuration does nothing)
- Android (Pico 4) and monado linux support (build scripts are not published yet)
- GUI server emulator (works without openxr runtime)
Clients:
- Audio with fifo pipes (tested with jack-stdio, should work with pulseaudio pipe sink/sources too)
- Monado driver with comp_target (monado interaction not published yet, WIP)
- Custom monado pacer synchronized with app for smoother framerate
- Monado builder with dynamic controller type switch (register all controller types)
Decomposer/Reconstructor:
- H264/HEVC VAAPI encoder (no ffmpeg used), linux only
- Haar decomposer compute pipeline
- BC1 reconstruction texture compression
- FXAA filter
- Android decoder
- ffmpeg decoder (software)
- Compute reconstruction pipeline (slow on Adreno)
- Graphics pipeline
- Foveated rendering (hard-coded scale)
Roadmap
Common:
- Choose better naming/branding
- Refactoring, better project structure (split utilities)
- Choose build system
- Code style (it's AWFUL now!!!)
- Imporve logging (use fmt_util if possible, remove extra
\n) - Shader combos to workaround SPIRV limitations
- Template combos (reduce unneeded branching)
- Improve vulkan utility
- New thread utility
- Optimize data layout to prevent false sharing
Server:
- Rec/Dec runtime configuration
- Configuration storage format
- GUI moving/toggle
- Improve gui monitoring (implot maybe)
- Interaction profile switches
- Emulate controllers in emulator GUI
- Timing information
- TCP streaming
- TCP keep-alive and reconnection
- UDP/mDNS broadcast
- SGSR/SGSR2 upscaling for reconstruction texture
- ffmpeg hwdec
- Multiple layers support (quad/cylinder layers)
- Depth/ASW in reconstruction data (16 bit or rgba block format)
- Disabling reconstruction (video rendering only)
Clients:
- Full jack/alsa/pulse audio clients
- HMDInfo shared cache, so runtime can start without server connection
- UDP listener for autoconnect
- Monado compositor bypass (allow sending layers as is)
- Monado in-process compositor (do we need IPC server when we already have server on HMD?)
- Improve decomposer postprocessing
- Passing depth to server (Seems to be unsupported with OpenComposite/monado now)
- SteamVR driver
- Vulkan Video encoder
- External encoders (nvenc/amf/ffmpeg/x265) in separate process (TODO: can we use GPL software with IPC such way???)
- OpenComposite driver (at least, we can send textures without extra swapchain copy and update overlays without xrEndFrame call, so this should be useful)
- Windows support (at least in vulkan video mode)
