MpvRx v1.5.0-preview.3

1.5.0-preview.3 — Preview Release

Playback Hotfix

• Audio and video transitions rebuilt: Every item is loaded with file-local video-track selection, preventing audio state from producing a black screen on the next video.
• Reliable next-item playback: Runtime navigation now sends an actual mpv loadfile replacement and clears the previous EOF pause state.
• Preference-safe EOF handling: Autoplay, Repeat One, Repeat All, Shuffle, playlist mode, and close-at-end now behave consistently, including very short audio files.
• Safe seeking: Audio never enters the native video-thumbnail path, and video thumbnails are generated only on demand while scrubbing—not automatically during file load.
• Separated render surfaces: The blob surface is mounted only for media independently identified as audio, preventing it from covering video during track-list transitions.
• True beat response: With audio-capture permission, real FFT data exclusively drives the blob; brightness and bloom are reduced while bass onsets pulse more clearly.

🔊 Audio Blob Visualizer

• OpenGL ES 3.0 blob visualizer — when playing audio without cover art, a reactive 3D blob appears behind the player controls. The blob morphs, pulses, and shifts color based on audio energy with a bloom/glow post-process.
• Touch rotation: Drag the blob to rotate it in 3D.
• Pinch zoom fixed: The blob now properly shrinks/enlarges when pinching — pinchScaleFromRenderer() was hardcoded to always return 1f, resetting zoom on every new gesture.
• Smaller default size: Camera distance increased so the blob fits cleanly within screen bounds instead of nearly filling the height.
• Audio Preferences toggle: New "Audio blob visualizer" switch in Settings > Audio to enable or disable it.
• Audio filter setting moved: Audio filter (compressor/equalizer) options now live in Audio Preferences instead of the player's MoreSheet.

🎬 yt-dlp Changes

• Audio quality preferences: Independent bitrate caps for Auto, 64, 128, 192, and 256 kbps — composed with existing codec, resolution, FPS, HDR, and container selectors.
• Serialized URL loading: Initial and replacement URL loads now use one cancellable serialized job, preventing overlapping libmpv commands when links are pasted rapidly.
• Graceful error recovery: Recoverable URL load failures return to the player UI with an error message instead of escaping to the process-wide crash handler.
• Audio quality removed from MoreSheet: yt-dlp audio quality selector moved from the player's MoreSheet to yt-dlp settings.

📻 Audio Browsing

• MediaStore + filesystem discovery for common audio formats, neutral media counts, audio MIME mapping, and Android 13 READ_MEDIA_AUDIO permission handling.
• Audio cards show metadata titles, embedded cover artwork when available (via audio-display=embedded-first), and a music-note fallback icon.
• Portrait-only playback — audio files force sensor-portrait orientation and prevent the rotation action from switching back to landscape.
• Sibling playlist includes audio — when "Include audio" is on, the next/previous track list includes audio files from the same folder.
• Audio icon placeholder fix: Exported icon now displays correctly for audio files without cover art.
• Audio pitch correction fix: Pitch correction no longer persists when switching to a new video — resets to default per-file.
• Audio autoplay race condition fixed: Eliminated a race condition that could cause audio files to fail starting playback.

🌐 Network & External Playback

• WebDAV PROPFIND fix: Connection checks now use a depth-zero PROPFIND request instead of Sardine's HEAD-based exists() call, making it work with servers like FileBrowser Quantum that reject HEAD on DAV collections.
• WebDAV trailing slash: Collection URLs consistently keep a trailing slash during validation and browsing.
• External-player discovery: Added a MIME-only intent filter so external-player pickers can find mpvRx before attaching the final video or audio URI.
• More protocol support: Added gopher://, sctp://, and data:// to network stream detection and intent filters.
• Stream compatibility improved: Better handling of edge-case media streams and improved browsing reliability.

🌲 Tree View Navigation

• Configurable path compression: New Off, 1–5, and Unlimited choices for single-child folder flattening. Applied independently per navigation step, preserving predictable physical paths. Tree View refreshes instantly when the depth changes.

🎨 Icon Consistency

• Converted all three painterResource(R.drawable.ic_material_symbols_check) usages to Icons.Default.Check through the app's AppIcon / Icon system.
• SectionHeader.leadingIcon and CompactExpressiveIconButton.imageVector now accept AppIcon instead of raw ImageVector, keeping everything on the unified icon pipeline.

🔊 Audio Playback Runtime Fixes

• local_media_path extra: Internal launches now pass the resolved filesystem path alongside the content URI, giving mpv a reliable fallback when content:// URIs fail.
• Serialized load dispatcher: Added a dedicated Dispatchers.Default.limitedParallelism(1) dispatcher for media loading — prevents race conditions when queuing multiple load commands.
• vid=auto before playback: Non-M3U file loads explicitly reset the video track to auto before loading, avoiding "no video track" state from previous audio-only plays.
• audio-display=embedded-first: Enabled MPV's embedded cover art rendering for audio files.
• Orientation on audio launch: setOrientation() checks isKnownAudioLaunch() immediately, before the track-list event settles — fixes the black-screen + landscape glitch on audio start.
• Subtitle "Off" option: Added an explicit "Off" choice in the player subtitle sheet so users can disable subtitles without cycling through all tracks.

🗑️ Folder Deletion Behavior

• Media-only deletion (default): Deleting a folder now only removes audio/video files — other files (images, logs, documents) are left untouched.
• "Delete folder + all contents" toggle: New option in Appearance Settings > File Browser to switch back to full recursive deletion when needed.
• Album View cleanup fix: Fixed an issue where the last video file in a folder was deleted but the empty folder remained.

📱 Tablet & Display

• Dynamic refresh rate: The player can now dynamically adjust the display refresh rate to match the video frame rate for smoother playback.
• Dual-pane navigation fix: Resolved a state leak that could cause crashes when navigating in tablet dual-pane mode.
• Dual-pane settings button hidden: The redundant settings button is no longer shown in dual-pane mode on tablets.
• Folder card height fix: Manual grid column counts now align properly with folder card heights in dual-pane layout.

🔍 Settings Search

• Search history: Recently searched terms are saved and displayed for quick re-selection.
• Search suggestions: The search field now shows contextual suggestions as you type.
• Reflection-based fallback: Settings search can dynamically discover settings via reflection when static indices are incomplete.
