What's new in v1.2

  • Dolby Vision Profile 5 on Android — correct colors, at last. P5 releases (no HDR10 base layer) used to render pink/green, then a black screen. zanzibarr now ships a custom-built playback engine for Android: mpv 0.41 + FFmpeg 8.1.2 + libplacebo 7.351 with Vulkan linked in. DV metadata is decoded on the dovi-preserving software path, reshaped on the GPU, and tonemapped to clean SDR on any display.
  • Works on real-world GPUs, not just the reference ones. The reshape path deliberately runs 8-bit textures, so it survives drivers that lack 16-bit linear sampling (Samsung Xclipse) as well as Adreno — verified on a Samsung Galaxy S23 FE and a Poco F6.
  • No more black screens on DV content. Playback startup no longer races the surface re-creation; the filter engages after the first frame instead.
  • Honest diagnostics in the player. The dynamic-range row in Video and audio settings now reports live engine status (applying / active / unavailable) with a tap-to-open technical detail panel — if a device can't run the correction, the app tells you instead of failing silently.

Already inside

  • Play instantly, never download — the Rust engine fetches only the segments you actually watch
  • True seek — yEnc begin/end segment mapping, accurate even on 100+ GB releases
  • Archive-aware — multi-volume RAR5 (incl. -hp encrypted) and split 7z (STORE, AES-256) reassembled in memory as one virtual, seekable file
  • Full picture pipeline — SDR / HDR / HDR10 / Dolby Vision selector with BT.2390 tone mapping; TrueHD/Atmos, DTS-HD MA, AV1, TrueHD 7.1
  • Smart Canvas — draw your own crop with live aspect preview, applied on the GPU
  • Player essentials — PiP, frame stepping, speed, audio sync, external audio/subtitle loading, double-click ±10 s seek
  • 14 languages — EN, TR, ES, DE, FR, PT, IT, RU, ZH, JA, KO, HI, AR, FA (RTL included), dark & light themes
  • Private by design — NNTP credentials live only in the OS keychain; no accounts, no telemetry, no cloud
