v3.0.0 - Fundamental changes on video playback and improved performance

What's New

This release introduces a complete rework of the video playback architecture, bringing significant performance improvements and better stability across different hardware configurations as well as compatibility for GNOME 46.

⚠️ Previous version is available on the legacy branch.

Performance

• Replaced CPU-bound St.ImageContent and appsink with more efficient gtk4paintablesink (should noticeably improve performance especially if hardware acceleration is available)
• Made framerate limiting optional — only enable it if needed, as it adds conversion overhead

Multi-Monitor

• Each monitor now gets its own dedicated video window while utilizing single gstreamer pipeline
• Improved window-to-monitor matching
• Better handling of monitor connect/disconnect during lock screen

Password Prompt

• Added grayscale effect when password prompt appears

Battery

• Added option to disable extension when running on battery power

Stability

• Fixed shell crash when _updateBackgrounds is called multiple times (lid close, monitor hotplug)
• Added gtk4paintablesink dependency check with notification on missing installation
• Fixed occasional video frame jump when pausing

Known Issues

• Possible audio and video desync after suspend/wake
• Possible clicking/crackling sounds when pausing/playing video with audio-
• Video positioning issues when connecting/disconnecting monitors with lock screen on

v2.0.0 — Scaling Modes, Audio & Pipeline Rewrite

What's New

Video Scaling Modes

• Added stretch, fit and cover scaling modes
• Cover mode correctly crops and centers video to fill the screen
• Fit mode preserves aspect ratio with letterbox/pillarbox

Fade-in Animation

• Configurable fade-in duration for smooth video appearance

Suspend/Wake Support

• Video automatically pauses on system suspend and resumes on wake

Transparent Video Support

• RGBA pipeline preserves alpha channel for transparent videos (.webm VP9)

Improvements

Pipeline Rewrite

• Default pipeline now uses playbin for better stability and built-in A/V sync
• Legacy parse_launch pipeline available as opt-in fallback in Debug settings

Multi-monitor

• Pipeline now initializes after all monitors are handled

Resource Cleanup

• Proper cleanup order in disable()

Debug Options

• Unsafe pipeline — use legacy parse_launch pipeline if experiencing artifacts
• Skip first frame — workaround for brief green frame at video start

Bug Fixes

• Fixed remove_signal_watch called without add_signal_watch

Known Issues

• Possible audio/video desync after suspend/wake
• Brief green frame at video start
• Performance issues with high-resolution videos (hardware dependent)
