PyShine Screen Recorder v1.0.7

PyShine Screen Recorder v1.0.7

What's New

• 100% A/V sync on long recordings — Producer-consumer architecture: capture thread pushes frames to a bounded 5-frame queue, dedicated writer thread paces at strict 30fps CFR by writing duplicate frames when queue is empty. Eliminates progressive A/V drift on long recordings.
• 1080p native resolution — Restored full 1920×1080 capture (no more 720p compromise). 4K monitors downscale to 1080p via 2×2 box filter.
• Professional dark-themed UI — Compact rectangular layout with 3-tier surface palette, indigo accents, circular icon buttons, horizontal stereo audio meter, side-by-side Capture/Monitor selectors.
• Help dialog — Press F1 or click the ? button for keyboard shortcuts (F9, F10, Enter, Escape) and a quick-start guide.
• PyShine branding — Logo + version pill + clickable www.pyshine.com link in the brand bar.

Bug Fixes

• Silent video regression — Audio gate decoupled from frame counter using dedicated first_frame_written flag.
• Synchronous stop retained — Background-thread stop broke A/V sync due to GIL contention on audio-level callback. Reverted to synchronous stop for perfect sync.

Downloads

• ScreenRecorder.exe — Standalone executable, no installation required.
• ScreenRecorder-v1.0.7-portable.zip — Portable zip version.

v1.0.6 — Near-Lossless Quality + A/V Sync Fix

What's New

Quality

• Near-lossless H.264 encoding (CRF 1, High profile, yuv420p) — visually indistinguishable from source, universally playable
• Box-filter downscaling for 4K monitors to 1080p — 2x2 area-averaging, the theoretically optimal method (no aliasing, no blurring)

Performance

• Cached GPU staging texture — staging texture created once and reused every frame, eliminating the per-frame GPU allocation that caused video stutter and freeze after 1-2 seconds
• Reduced DXGI timeout from 50ms to 16ms (matches 60Hz display refresh)

A/V Sync

• Duplicate-frame catch-up — when the pipeline falls behind, duplicate frames are written to fill the gap (instead of skipping), ensuring the video timeline never falls behind audio
• Audio start gate — audio starts immediately but drops data until the first video frame is written

UI

• PyShine logo in toolbar
• Delete recordings from disk when removed from history
• F9 hotkey for start/stop
• Removed file size (MB) display from status bar
• Fixed Qt.TransformationMode enum (PyQt6)

Downloads

• \ScreenRecorder.exe\ — standalone executable, no installation required

Screen Recorder v1.0.5

Screen Recorder v1.0.5

What's New

UI Improvements

• Added PyShine logo to the main window toolbar (visible brand mark in top-left corner)
• Set Windows AppUserModelID for proper taskbar icon grouping
• Removed file size (MB) display from the status bar — now shows only duration and FPS for a cleaner UI

Icon & Branding

• Regenerated app.ico with 7 sizes (16, 24, 32, 48, 64, 128, 256) including 256x256 for high-DPI displays
• Fixed EXE icon embedding — icon now properly embedded as a Windows PE resource
• Added clear_icon_cache.bat utility to clear stubborn Windows icon cache

Bug Fixes

• Fixed file deletion — files removed from the history panel are now actually deleted from disk
• Fixed Qt.TransformationMode enum (PyQt6 uses TransformationMode, not SmoothingMode)
• Cleaned up verbose debug logging

What's Changed

v1.0.2 - Crash Fix Release

What's Fixed in v1.0.2

Critical Bug Fixes

• Fixed app crash/exit when starting recording - The app would immediately exit when clicking the record button due to thread-affinity issues with mss (screen capture library) and Qt's QThread model.
• Fixed mss thread-local GDI handle errors ('_thread._local' object has no attribute 'srcdc') at high frame rates (60fps).
• Rewrote recording pipeline using Python's native threading.Thread with thread-safe queues instead of QThread+QTimer, ensuring mss GDI handles are created and used within the same thread.
• Fixed pyqtSlot signature mismatch between audio_data signal and write_audio_data slot that prevented audio from being passed to the encoder.
• Added automatic hardware encoder fallback - When hardware encoders (QSV/NVENC/AMF) are not available, automatically falls back to software libx264 instead of crashing.
• Improved mss resource cleanup on recording stop, handling thread-local handle errors gracefully.
• System audio (WASAPI loopback) now works correctly when the microphone is turned off.

Technical Changes

• New RecordingWorker class using threading.Thread with audio/command queue.Queue for cross-thread communication.
• Frame timing maintained with time.perf_counter() for precise fps capture.
• Removed dependency on QThread/QTimer for the capture/encoding loop.
• Audio data delivered via thread-safe queue instead of relying solely on Qt signals cross-thread.

Screen Recorder v1.0.1

Bug Fixes

Fixed: System audio recording when microphone is disabled

This release fixes a critical issue where system audio (from videos, music, or any audio playing on your computer) was not being recorded when the microphone was turned off.

Changes:

• Fixed WASAPI loopback device discovery: replaced non-existent API call with get_default_wasapi_loopback() and added 3 fallback strategies
• Fixed audio format: WASAPI loopback devices require paInt16 (not paFloat32) — added proper int16→float32 conversion
• Fixed audio array shape: always reshaped to 2D (frames, channels) for encoder compatibility
• Fixed stream startup: added start=False before explicit start_stream() to ensure callbacks fire correctly
• Added auto-fallback: system audio is automatically enabled when microphone is disabled, preventing silent recordings
• Fixed get_actual_channels() to report loopback channel count when microphone is off

Files:

• ScreenRecorder.exe — Windows 64-bit standalone executable
