Add spec-compliant dvh1 HLS variant for Dolby Vision Profile 5 (#16362)

2026-03-28T21:12:06Z

* Add spec-compliant dvh1 HLS variant for Dolby Vision Profile 5 DV Profile 5 has no backward-compatible base layer, so SUPPLEMENTAL-CODECS cannot be used. The master playlist currently labels P5 streams as hvc1 in the CODECS field, even though DynamicHlsController already passes -tag:v:0 dvh1 -strict -2 to FFmpeg for P5 copy-codec streams, writing a dvh1 FourCC and dvvC configuration box into the fMP4 init segment. This mismatch between the manifest (hvc1) and the bitstream (dvh1) causes spec-compliant clients like Apple TV and webOS 24+ to set up an HDR10 pipeline instead of a Dolby Vision one. Add a dvh1 variant before the existing hvc1 variant for P5 copy-codec streams. Both variants point to the same stream URL. Spec-compliant clients select dvh1 and activate the DV decoder path. Legacy clients that reject dvh1 in CODECS fall through to the hvc1 variant and detect DV from the init segment, preserving existing behavior. Fixes #16179 * Address review: support AV1 DoVi P10, add client capability check - GetDoviString: add isAv1 parameter, return dav1 FourCC for AV1 DoVi (P10 bl_compat_id=0) and dvh1 for HEVC DoVi (P5) - Remove redundant IsDovi() check; VideoRangeType.DOVI is sufficient and correctly limits to profiles without a compatible base layer - Replace IsDoviRemoved() with client capability check using GetRequestedRangeTypes(state.VideoStream.Codec) to only emit the dvh1/dav1 variant for clients that declared DOVI support - Update comments and doc summary to reflect P5 + P10/bl0 scope * Use codec string instead of boolean for DoVi FourCC mapping Replace bool isAv1 with string codec in GetDoviString for future-proofing when DoVi extends to H.266/VVC or AV2. * Move AppendDoviPlaylist next to AppendPlaylist * Fix SA1508: remove blank line before closing brace * Use AppendLine() instead of Append(Environment.NewLine)

Fix malformed query string in StreamInfo.ToUrl() causing 500 error via proxies

2026-02-18T20:08:35Z

StreamInfo.ToUrl() generated URLs like `/master.m3u8?&DeviceId=...` (note `?&`) because `?` was appended to the path and all parameters started with `&`. When the first optional parameter (DeviceProfileId) was null, the result was a malformed query string. This is harmless when clients hit Jellyfin directly (ASP.NET Core tolerates `?&`), but when accessed through a reverse proxy that parses and re-serializes the URL (e.g. Home Assistant ingress via aiohttp/yarl), `?&` becomes `?=&` — introducing an empty-key query parameter. ParseStreamOptions then crashes on `param.Key[0]` with IndexOutOfRangeException. Changes: - StreamInfo.ToUrl(): Track query start position and replace the first `&` with `?` after all parameters are appended, producing valid query strings - ParseStreamOptions: Guard against empty query parameter keys - Tests: Remove .Replace("?&", "?") workaround that masked the bug Co-Authored-By: Claude Opus 4.6
