Limin Wang ad3ef00ce5 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.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

libavcodec provides implementation of a wider range of codecs.
libavformat implements streaming protocols, container formats and basic I/O access.
libavutil includes hashers, decompressors and miscellaneous utility functions.
libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.

Examples
