Release v1.4.1 · mikecerisano/NDIStream

Recommended over v1.4.0 — same features, plus two fixes from a Codex review.

What changed since v1.4.0

Audio fallback extended from 150ms → 1000ms. When recording with audio enabled, the writer holds the first video frame until audio arrives. Old timeout was too tight for "audio enabled at broadcast start" — mic could easily arrive 200–400ms into AVCaptureSession warmup, causing recordings to silently become video-only with no user-visible signal.
Audio-missing warning surfaces in UI. If the 1s timeout fires (no audio in the first second), the red error label now shows "No audio in first second — recording video only" so you know what happened.
release.sh tag fix. v1.4.0's git tag pointed at the wrong commit (v1.3.0 code) because the release script created the GitHub release before the commit was pushed. v1.4.1 onward commits + pushes first, then creates the release pinned to the right SHA.
