Sebastian Dröge 67088dcea6 gst/deinterlace2/: Get rid of speedy.[ch] as we don't use most of it's code anyway and it doesn't seem to be relicens...
Original commit message from CVS:
* gst/deinterlace2/Makefile.am:
* gst/deinterlace2/gstdeinterlace2.c: (gst_deinterlace2_init):
* gst/deinterlace2/tvtime/greedy.c: (deinterlace_frame_di_greedy):
* gst/deinterlace2/tvtime/greedyh.c:
(deinterlace_frame_di_greedyh):
* gst/deinterlace2/tvtime/speedtools.h:
* gst/deinterlace2/tvtime/speedy.c:
* gst/deinterlace2/tvtime/speedy.h:
* gst/deinterlace2/tvtime/tomsmocomp.c: (Fieldcopy):
* gst/deinterlace2/tvtime/tomsmocomp/TomsMoCompAll.inc:
* gst/deinterlace2/tvtime/vfir.c: (deinterlace_frame_vfir):
Get rid of speedy.[ch] as we don't use most of it's code anyway
and it doesn't seem to be relicensed to LGPL. Use memcpy() instead
of the speedy memcpy everywhere instead.
* gst/deinterlace2/gstdeinterlace2.h:
Remove many unused declarations.
