An element the enum cannot parse throws, and the configuration manager
catches that and returns defaults, so one bad preset discarded every other
encoding setting.
- serialize EncoderPreset through a string surrogate in XML
- fall back to auto for an empty, unknown or out-of-range value
A transcode that is not in the store is invisible to the other replicas, so the
HLS entry points have to publish and hold the lease themselves.
- register the play session in the store when ffmpeg starts
- renew the lease on a background loop and delete the session when it ends
- shorten segments and bound the playlist window when resuming a stored session
- add RecoverySegmentLengthSeconds and RecoverySegmentBufferCount encoding options
Dolby vision files having unexpected transfers now also marked as invalid, and it will now get its base video range from its base layer color transfer, as not all invalid dolby vision files are HDR now.
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/<id>/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.
* Add support for VobSub subtitle streams
* update logic to determine separate extraction for VobSub subtitles
* simplify VobSub extraction logic and fix ffmpeg command
* Match `ExtractAllExtractableSubtitlesMKS` with `ExtractAllExtractableSubtitlesInternal` Matroska's VobSub option
* Add a comments clarify why MKS was used, and remove the redundant VobSub extension branch
* remove redundant VobSub format check
* fix type errors
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
