Fix zh-CN subtitle language display

2026-01-05T11:22:44Z

The DisplayTitle property was using .NET's CultureInfo.GetCultures(NeutralCultures) to resolve language display names. Since zh-CN is a specific culture (not neutral), it would fall back to the base 'zh' code, resulting in generic 'Chinese' instead of 'Chinese (Simplified)'. This change adds a LocalizedLanguage property to MediaStream that gets populated via LocalizationManager.FindLanguageInfo() when streams are retrieved from the database. This leverages Jellyfin's existing iso6392.txt mappings which correctly map zh-CN to 'Chinese (Simplified)'. The same pattern is already used for other localized strings like LocalizedDefault and LocalizedExternal.

Translate the ISO-639-2/B codes to ISO-639-2/T. (#13068)

2025-04-08T03:29:12Z

* Translate the ISO-639-2/B codes to ISO-639-2/T. This enables 19 additional languages to be displayed correctly. * Convert the 2-dimensional array to a dictionary * Added the French language to the list of ISO-639-2/B codes * Don't change the property, use a local variable instead. * When creating the MediaStream in the MediaStreamRepository ensure that the ISO 639-2/T (f.e. deu) code is used for the language as that is the one the .NET culture info knows. The other code is most likely the ISO 639-2/B code (f.e. ger) which is unknown to the .NET culture info and will result in just displaying the code instead of the display name. * Move the substitution of ISO 639-2/B to /T to the localization manager. Some language (like Chinese) have multiple entries in the iso6392.txt file (f.e. zho|chi|zh|..., zho|chi|zh-tw|...) but the conversation between /T and /B is the same so use .TryAdd. * Change the method definition from GetISO6392TFromB to TryGetISO6392TFromB and return true if a case was found. * Add unit tests for TryGetISO6392TFromB.

Improve dynamic HDR metadata handling (#13277)

2025-04-03T00:06:02Z

* Add support for bitstream filter to remove dynamic hdr metadata * Add support for ffprobe's only_first_vframe for HDR10+ detection * Add BitStreamFilterOptionType for metadata removal check * Map HDR10+ metadata to VideoRangeType.cs Current implementation uses a hack that abuses the EL flag to avoid database schema changes. Should add proper field once EFCore migration is merged. * Add more Dolby Vision Range types Out of spec ones are problematic and should be marked as a dedicated invalid type and handled by the server to not crash the player. Profile 7 videos should not be treated as normal HDR10 videos at all and should remove the metadata before serving. * Remove dynamic hdr metadata when necessary * Allow direct playback of HDR10+ videos on HDR10 clients * Only use dovi codec tag when dovi metadata is not removed * Handle DV Profile 7 Videos better * Fix HDR10+ with new bitmask * Indicate the presence of HDR10+ in HLS SUPPLEMENTAL-CODECS * Fix Dovi 8.4 not labeled as HLG in HLS * Fallback to dovi_rpu bsf for av1 when possible * Fix dovi_rpu cli for av1 * Use correct EFCore db column for HDR10+ * Undo outdated migration * Add proper hdr10+ migration * Remove outdated migration * Rebase to new db code * Add migrations for Hdr10PlusPresentFlag * Directly use bsf enum * Add xmldocs for SupportsBitStreamFilterWithOption * Make `VideoRangeType.Unknown` explicitly default on api models. * Unset default for non-api model class * Use tuples for bsf dictionary for now

Order MediaStream query by StreamIndex (#13506)

2025-02-06T14:15:29Z

Our stream index calculation logic implemented in #7529, assumes an in-order array. However, our current query may return out-of-order items, leading the server to pass an incorrect index to ffmpeg, causing the transcoding to crash.
