Scene change detection plugin for VapourSynth, using xvid

Description

Scene change detection plugin for VapourSynth, using xvidcore.

Converted from the Avisynth plugin written by Fredrik Mellbin.

Usage

::

scxvid.Scxvid(clip clip[, string log="", bint use_slices=True])

Parameters: clip Input clip. Must be YUV420P8 with constant format and dimensions.

*log*
    Name of the xvid first pass log file.

*use_slices*
    This should make Scxvid faster, at the cost of slight differences in
    the scene change detection.

The log parameter is optional, because the _SceneChangePrev property will be attached to every frame. Thus some users may not need xvid's log file.

For correct scene change detection, one must request all the frames, starting at 0, strictly in ascending order. It's probably best if Scxvid is the last filter in the chain.

Compilation

::

./autogen.sh
./configure
make

Note: when compiling for Windows, you must prefix the xvidcore library's file name(s) (xvidcore.dll and xvidcore.dll.a, or xvidcore.a) with "lib", or Scxvid's build system won't pick it up. This is thanks to xvidcore's special snowflake build system, which reinvents libtool.
