From ad3ef00ce513beee3e22a910e75f40d324a6a7ad Mon Sep 17 00:00:00 2001 From: Limin Wang Date: Tue, 13 Aug 2019 09:39:47 +0800 Subject: avfilter/f_select: yuv will use Y plane only for scenecut detect At the moment scene change detection score uses all planes to detect scene changes. In this regard this is similar how the frozen frames detection works. However, in classic encoding scene change detection typically only uses the Y plane. We might get more resonable scores for scene change if we also use only the Y plane for calculating the score if the pixel format is YUV. Although this will require additional work once packed YUV formats are added, because for the moment the generic scene sad score calculation has no way to ignore some components in a packed format.
