+ *   - Video: H.263, H.264, H.265, VP8, VP9, AV1
+ *   - Audio: Vorbis, Opus, FLAC, ALAC, PCM, MP3, AAC, AC-3, E-AC-3, DTS,
+ *     DTS-HD, TrueHD
+ *
+ * Hardware decode (MediaCodec) handles whatever the device ships with;
+ * the rest fall through to FFmpeg software decode via the Jellyfin-published
+ * `org.jellyfin.media3:media3-ffmpeg-decoder` extension wired up with
+ * `DefaultRenderersFactory.EXTENSION_RENDERER_MODE_PREFER` (see
+ * ExoPlayerView.kt:ensurePlayer).
+ *
+ * Cross-checked against the reference-device probe in
+ * docs/research/hdr-dv-atmos-tv-plan.md (Amlogic Android 14 TV; HDMI sink
+ * accepts AC3/EAC3 as bitstream and multichannel PCM up to 7.1 @ 192 kHz,
+ * so software-decoded DTS/DTS-HD/TrueHD reach the sink as PCM).
+ *
+ * Dolby Vision: the CodecProfile below uses `NotEquals VideoRangeType
+ * DOVI`, which in Jellyfin's semantics blocks ONLY pure Profile 5
+ * (IPTPQc2 — the stream that renders purple/green without a DV-aware
+ * decoder). DV Profiles 7/8 with HDR10 or SDR base layers (Jellyfin
+ * reports these as `DOVIWithHDR10`, `DOVIWithHDR10Plus`, `DOVIWithEL`)
+ * are NOT blocked — Media3 1.9.1+ correctly falls back to the AVC/HEVC
+ * base layer.
+ *
+ * Containers limited to Media3's bundled extractors. FLV is intentionally
+ * absent — Media3 has no FLV extractor (MPV claims it via FFmpeg).
