Stop image endpoints from upscaling beyond the source resolution

2026-08-07T15:33:37Z

ImageHelper.GetNewImageSize passed the caller-supplied width/height straight through to SkiaEncoder.EncodeImage, which allocates an SKImageInfo of exactly that size. Nothing bounded those values against the source image, so a request like Items//Images/Primary?width=23100&height=23100 made the server allocate and resample a 23100x23100 surface from, say, a 600x336 poster: the reporter measured 100% of a core for 10-15 minutes and 6-12 GB resident per request. The item images endpoints do not require authentication, so any caller who knows an item id can trigger this, and varying the size by one pixel misses the cache every time. Add DrawingUtils.ScaleDownToFit, which scales a size down uniformly until it fits inside a bounding box and returns it unchanged if it already does, and apply it in GetNewImageSize against the original image dimensions. Requests that ask for more pixels than the source now get the source resolution back, scaled to the requested aspect ratio. Downscaling paths are untouched, and DrawingUtils.Resize keeps its existing behaviour for the transcoding callers in EncodingJobInfo and StreamInfo, which legitimately size video output. ResizeFill already refused to upscale; this makes width/height consistent with fillWidth/fillHeight. Fixes #17056.

Embed external subtitles into MKV when transcoding

2026-05-19T11:03:07Z

Allow external subtitle files (SRT, ASS, PGS, etc.) to be muxed into MKV output containers when the device profile requests Embed delivery. Previously, the IsExternal guard in GetSubtitleProfile excluded external subtitles from Embed consideration entirely, forcing them to be served as separate sidecar files even when the output container supports embedding. Changes: - Extract CanConsiderEmbedSubtitle in StreamBuilder to allow external subs through when transcoding to MKV - Add external subtitle file as FFmpeg input (-i) for Embed delivery - Map external embedded subs from the correct FFmpeg input index - Fix external audio map index to account for the new subtitle input - Extract NeedsExternalSubtitleMuxing in EncodingHelper to deduplicate the external subtitle input check Fixes #16403

Respect EnableSubtitleExtraction setting in subtitle delivery

2026-03-13T15:34:44Z

Wire up EnableSubtitleExtraction config to MediaEncoder.CanExtractSubtitles so the setting is actually respected. Gate subtitle extraction check behind PlayMethod.Transcode since DirectPlay has no competing ffmpeg process. Add parameterized tests for StreamBuilder.GetSubtitleProfile covering text and graphical codecs, profile format matching, and extraction setting behavior. Remove misplaced SubtitleEncoder extraction test.
