Regira Media

Regira Media provides video processing — compression and snapshot extraction — via FFMpeg.

Projects

Project	Package	Backend
Media.FFMpeg	Regira.Media.FFMpeg	FFMpegCore

Installation

<PackageReference Include="Regira.Media.FFMpeg" Version="6.*" />

FFMpeg binaries must be available on PATH or configured via FFMpegCore.GlobalFFOptions.

VideoManager

Implements ICompressService and IVideoService.

var vm = new VideoManager();

Get video metadata

VideoSettings? info = await vm.GetInfo(videoFile);
// info.Width, info.Height, info.Duration, info.Codec, …

Compress

Encodes to VP9/WebM. Returns null if the source is already smaller than the target.

IMemoryFile? compressed = await vm.Compress(videoFile, new VideoSettings
{
    // override resolution, bitrate, codec, etc.
});

SnapshotService

Extracts a single frame as an IImageFile.

var snapshots = new SnapshotService(imageService);

IImageFile? thumb = await snapshots.Snapshot(videoFile,
    size: new Size2D(640, 360),
    time: TimeSpan.FromSeconds(5));

Parameter	Type	Default	Description
input	IBinaryFile	(required)	Source video
size	Size2D?	null	Output dimensions
time	TimeSpan?	null	Frame position (defaults to first frame)

Notes

• SnapshotService requires an IImageService (inject Regira.Drawing.SkiaSharp.Services.ImageService).
• Output codec is VP9 / WebM.
• Requires FFMpeg binaries (ffmpeg, ffprobe) on the host.
