ShotDetector.FastYuv

Optional fast path for ShotDetector: with it, ffmpeg sends raw yuv420p and ShotDetector converts only the ~7% of pixels its resize reads, instead of ffmpeg converting every full frame to BGR. Results are identical; on 1080p video detection takes about 10 s instead of 17 s for 5000 frames.

using ShotDetector;
using ShotDetector.FastYuv;

var result = ShotDetection.Detect("video.mp4", new DetectionOptions { Yuv420Converter = new SwscaleYuv420() });

It also has Yadif, a port of FFmpeg's yadif deinterlacer, row by row: with in-process decoding and deinterlacing on, only the rows the resize reads are deinterlaced (identical results; on 1080i25 MPEG-2 with 2 CPUs, 7.5 s instead of 11.6 s for 2000 frames). It is a FrameReader IRowDeinterlacer, so a FrameDecoder takes it too (FrameDecoderOptions.RowDeinterlacer).

var result = ShotDetection.Detect("broadcast.mxf", new DetectionOptions { Deinterlace = DeinterlaceMode.Auto, Yadif = new Yadif() });

The converter is a bit-exact port of FFmpeg libswscale's yuv420p → BGR24 conversion (verified for all 2^24 Y/U/V values), so this package is licensed under the GNU LGPL 2.1 or later (COPYING.LGPL). The ShotDetector package itself is MIT. Video that isn't 8-bit yuv420p with an even height uses the normal path anyway.
