This patch fixes issue #16032 where the Playlists media folder ignored a user-uploaded Primary image and kept showing the generated collage. The root cause was DTO image precedence on UserView items for CollectionType.playlists. We now prefer the display parent (PlaylistsFolder) Primary image when available by clearing the UserView Primary tag and setting ParentPrimaryImageItemId/ParentPrimaryImageTag. Added tests cover both paths: parent custom image preferred, and fallback to existing UserView Primary when parent has none.
- Add missing param and returns XML doc tags (SA1611, SA1615)
- Remove trailing alignment whitespace in test attributes (SA1025)
- Use nullable string parameter for null test case (xUnit1012)
Encoders sometimes produce sample aspect ratios like 3201:3200
(0.03% off square) for content that has effectively square pixels.
The exact string comparison against "1:1" marks these as anamorphic,
which triggers unnecessary transcoding on clients that require
non-anamorphic video.
Parse the SAR ratio numerically and treat values within 1% of 1:1
as square pixels. This threshold is well clear of the nearest real
anamorphic SAR (PAL 4:3 at 16:15 = 6.67% off).
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

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.
When a password hash is missing the 'iterations' parameter, Verify now
throws a descriptive FormatException instead of KeyNotFoundException.
- Extract GetIterationsParameter() helper method to avoid code duplication
- Provide distinct error messages for missing vs invalid parameters
- Add comprehensive unit tests for CryptographyProvider
When querying items with recursive=true, items with types from removed
plugins would cause a 500 error. Now these items are skipped with a
warning log instead of throwing an exception.
Fixes#15945
