iMirror v0.7.0

v0.7.0 ships the Vortice GPU modernization and the fail-closed update hardening from the B3/Gate B validation cycle.

Highlights

  • Vortice.Windows is now the default and only high-resolution D3D GPU binding.
  • Removed the deprecated SharpDX GPU binding packages and the IMIRROR_GPU_BINDING selector flag.
  • Auto-update now fails closed: installs are blocked if SHA256SUMS is missing, unreachable, unparseable, does not name the setup asset, or the setup hash does not match.
  • AirPlay receiver startup cleans up partial mDNS/audio starts so transient bind or startup failures can be retried cleanly.
  • H.264 stream gating now retains SPS and PPS independently, so separate SPS-only and PPS-only packets are both prepended to the next IDR.
  • Fixed mangled readiness/log separators.

Installation

Recommended:

  1. Download and run iMirror-0.7.0-setup.exe.

Portable fallback:

  1. Download the iMirror-0.7.0-win-x64.zip asset.
  2. Extract the zip.
  3. Run iMirror.exe.

Known limitations

  • The FFmpeg software-decode fallback remains functional but exceeded the 150ms latency gate in real-device B3 validation. The GPU path passed the gate. See #32.
  • Display-audio endpoint power-cycling can leave WASAPI audio muted until reconnect when audio is routed through that display. This was reproduced on both SharpDX and Vortice, so it is tracked as a binding-independent existing product issue. See #35.
  • This package is unsigned; Windows SmartScreen may show a warning.

Validation

  • B3 real-device gate: GPU path PASS, auto-update fail-closed PASS, FFmpeg fallback functional but latency-failing.
  • Vortice Gate B A/B: Mac same-session SharpDX 30m PASS (worstP95=38ms, worstMax=70ms) vs Vortice 30m PASS (worstP95=63ms, worstMax=68ms).
  • iPhone Vortice GPU, reconnect, diagnostic probes, and software fallback checks passed.
  • Release workflow passed on windows-latest: tests, pinned FFmpeg download with SHA-256 verification, self-contained win-x64 publish, package zip verification, Inno installer build, checksum generation, and GitHub Release upload.

Notes

  • FFmpeg Essentials is bundled under tools\ffmpeg\bin with its license file.
  • The app is self-contained for .NET 10.
  • SHA-256 checksums are published in SHA256SUMS.
