FluxCast v0.1.2: Native Wayland Miracast for Linux (Hyprland/Sway/KDE/GNOME)

Hi r/linux,

I’m the developer of FluxCast, an open-source tool built to solve the Miracast/Wi-Fi Direct screen mirroring pain on Linux. After landing on the official ArchWiki, I’m pushing v0.1.2 with major fixes for hardware compatibility.

What FluxCast does:

Native Wayland support: Full compatibility with compositors like Hyprland, Sway and DE like KDE, and GNOME.
Low Latency: Uses GStreamer/FFmpeg for real-time RTSP/RTP streaming (\~1s delay).
Multi-Channel Concurrent (MCC): Works concurrently with your regular Wi-Fi connection, not like Miraclecast.
Easy installation: Available via PyPI, AUR, or as a standalone AppImage.

Recent Low-Level Fixes & Updates:

LG webOS: Solved stream drops caused by randomized P2P MAC addresses during RTSP handshakes.
Samsung Tablets & Minimal Sinks: Added force-mode fallback for minimal-capability WFD targets (tested on Galaxy Tab S9 FE).
1200p VESA Support: Implemented native 1920x1200 resolution support for VESA-compliant displays.
Performance Tuning: Aligned high-res streams (>1080p) to the ultrafast encoder preset and raised bitrate floors to prevent buffering lag.

Hardware Lab Initiative: I’m currently tackling a "tin can" audio bug on the Microsoft 4K Wireless Adapter. As a student developer, I don't have access to every proprietary dongle, so I’ve started a transparent hardware fund on Ko-fi to build a testing bench.

100% Transparency: All funds go strictly toward used hardware (starting with a $60 unit in Brno). I will post photos of all acquired gear directly to the GitHub issue tracker for verification.
How you can help: If you rely on FluxCast, please consider supporting the testing fund. If not, even testing or providing logs is a huge help!
