Merge commit 'a786c8259dafeca9744252230b5d78f67810770c'
* commit 'a786c8259dafeca9744252230b5d78f67810770c': idct: Split off Xvid IDCT Conflicts: libavcodec/Makefile libavcodec/mpeg4videodec.c libavcodec/x86/Makefile libavcodec/x86/idctdsp_init.c This split is somewhat restructured leaving the xvid IDCT available outside mpeg4 if manually selected. The code also could not be merged unchanged as it conflicted with a bugfix in FFmpeg Merged-by: Michael Niedermayer <michaelni@gmx.at>
