Implemented BOSS features in Odyssey
These capabilities are integrated in BOSS-enabled Odyssey builds. Controls and playback routes vary by platform, source and build; a listed capability is not a claim that every file and output combination has passed testing.
| Capability | What it means in Odyssey |
|---|---|
| Dolby Vision sources | Profile 5 and Profile 8 handling on compatible playback routes; Profile 7 MEL and FEL use their dedicated paths below. |
| Profile 7 MEL | Implemented MEL-to-Profile 8.1 compatibility playback, demonstrated inside Odyssey on Apple TV. |
| Profile 7 FEL | Implemented base-layer and enhancement-layer reconstruction using the source RPU metadata. Picture and sound demonstrated with BOSS in Odyssey on Apple TV, without KSPlayer fallback. |
| 4K, HDR10 and SDR | Hardware-assisted playback with source resolution, transfer and colour information. 4K HDR10 and SDR have physical Odyssey playback evidence. |
| HDR10+ metadata | Dynamic-metadata handling is implemented on supported BOSS routes. Actual HDR10+ output depends on the device and display path; display processing is not independently qualified. |
| MKV, MP4 and AVI | Container playback through supported BOSS decoding routes, including high-bitrate MKV remuxes. The video, audio and subtitle codecs inside a file still determine compatibility. |
| Live HLS and MPEG-TS | Live source playback and play/pause controls; seeking is offered when the source exposes a seekable window. This is separate from a full local DVR feature. |
| Hardware acceleration | Apple hardware decoding for supported codecs and profiles, with route-dependent compatibility handling. |
| Playback controls | Play, pause, seeking, skip controls and resume integration within Odyssey's player interface. |
| Scrub thumbnails | Preview images associated with the selected position on supported seekable sources. Availability depends on the source and route. |
| Audio tracks and multichannel sound | Choose available soundtracks and use supported multichannel output. Decoded surround sound is not a blanket Atmos object-output guarantee. |
| Embedded subtitles | Select exposed text and image subtitle tracks, including supported ASS styling and embedded fonts; rendering depends on the playback route. |
| External subtitles | Supported external SRT/WebVTT tracks and optional OpenSubtitles results, with language and appearance controls. |
| Dual subtitles | Main and secondary subtitle selection on supported BOSS routes. |
| Offline subtitle translation | English text subtitles to 13 target languages on BOSS-enabled iPhone, iPad and Apple TV builds, once the required model is available locally. Live caption translation is not supported. |
| Picture in Picture | System PiP on supported routes, with return-to-player integration. Availability is shown by the active route. |
| In-app mini-player | A persistent playback surface that can minimise while you browse, on supported layouts. |
| Source switching | Choose an alternate available source from within Odyssey's player, retaining source-access checks. |
| Caching and cache controls | Bounded buffering and supported disk-cache routes, with BOSS cache inspection and clearing in Odyssey. |
| Actual video statistics | Stream resolution, codec and colour information, plus available Dolby source-profile, layer and processing information. Unknown metadata remains unknown. |
| Player choice and fallback | BOSS Player Engine is the main engine. On iPhone, iPad and Apple TV, choose BOSS, AetherEngine or KSPlayer as your default, enable or disable each engine and set the fallback order. Mac offers BOSS and KSPlayer. |
| Local playback diagnostics | Detailed local source, decoding, rendering and playback errors to help distinguish a provider failure from an engine or output problem. |
Offline translation languages: Thai, Spanish, French, German, Italian, Portuguese, Japanese, Simplified Chinese, Arabic, Hindi, Vietnamese, Indonesian and Russian. Translation uses supported English text subtitle tracks; it does not translate the soundtrack or burned-in text.
Working MEL and FEL playback count as implemented features. Independent Dolby picture conformance and HDMI output precision are separate qualification tasks. Profile 7 compatibility/reconstruction is not a promise of unchanged Profile 7 transport. Seek/resume and demanding-source reliability remain active areas of improvement.
