Browse source 
Original commit message from CVS:
2005-10-26  Julien MOUTTE  <julien@moutte.net>

* gst/videobox/Makefile.am: Use liboil.
* gst/videobox/gstvideobox.c: (gst_video_box_class_init),
(gst_video_box_set_property), (gst_video_box_transform_caps),
(gst_video_box_set_caps), (gst_video_box_get_unit_size),
(gst_video_box_ayuv): Lot of optimization in AYUV rendering
using liboil. Will dot the same to I420 border generation
tomorrow.
