* Filter YUV scaling at half size and below with center of pixelfbarchard@chromium.org2010-04-161-3/+6
| | | | | | | | | BUG=19113 TEST=use playerwtl and reduce size to half and turn filtering on/off. Should look better. Review URL: http://codereview.chromium.org/1625017 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@44760 0039d316-1c4b-4281-b951-d872f2087c98

| | | | | | | | | BUG=18449,20718 TEST=play a video on linux without scaling and it should go 4 times faster than with scaling. Review URL: http://codereview.chromium.org/174442 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@25001 0039d316-1c4b-4281-b951-d872f2087c98
* YUV with clipping.fbarchard@chromium.org2009-05-181-76/+251
| | | | | | | | | | | | All functions do 2 pixels at a time. 90 and 270 rotations implemented. YV16 refactored. YV12 code accepts a YuvType that allows the same code to support YV16 as well. Special case for half size removed. Special case for doubling added. 3.62 ms versus 8.62 for general purpose code.

* YUV scaling and conversion refactored into low levels per platform that do a ↵fbarchard@chromium.org2009-05-131-0/+408
row and high levels that step thru the image. Low level is implemented in MMX assembly. Mac and Linux use reference code for this version. Review URL: http://codereview.chromium.org/113247 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@16011 0039d316-1c4b-4281-b951-d872f2087c98
