DSVP v0.1.5-beta

What's New

Image Quality

• Chroma siting correction — reads chroma_location from stream metadata, applies sub-texel UV offset before Catmull-Rom sampling
• Lanczos anti-ringing clamp (0.8 strength) — prevents overshoot/halo artifacts on sharp edges
• Temporal dithering — blue noise texture offset cycles per-frame, breaks up banding on static scenes
• Blue noise dither upgrade — improved spectral quality

PGS Subtitle Fix

• Fixed PGS bitmap subtitles in MKV containers — detects and decompresses zlib-compressed PGS packets that FFmpeg's matroska demuxer passes through raw

UI/UX

• Folder navigation — B/N keys and clickable prev/next buttons to jump between media files in the current folder
• Play button window icon replacing old DSVP text icon
• Fullscreen overlay scaling (2x for seek bar, menu bar, idle screen)
• Fixed idle screen color bleed on compositor gap (Steam Deck / Gamescope)
• Fixed green flash on file open
• Fixed fullscreen aspect ratio stretch on new file open

Docs

• README, SETUP, and SteamOS docs updated with new controls, corrected build instructions, and zlib dependency
