Diego Biurrun 5a6e3c039c swscale: Mark all init functions as av_cold 2012-07-23 01:30:05 +02:00
Ronald S. Bultje 7f77e9041a swscale: clip before assigning tables in RGB output functions. 2012-04-14 16:29:24 -07:00
Ronald S. Bultje 4860625236 swscale: fix off-by-one in second coefficient in bilinear filters. 
If coefficient A is 12-bits xixed-point number "X", then the other
coefficient is (1 << 12) - X, not (1 << 12) - X - 1.

Ronald S. Bultje 9206ac80a5 swscale: handle last pixel if lines have an odd width. 
Fixes bug 270.
 2012-04-13 14:21:58 -07:00
Ronald S. Bultje bc0bdda77b swscale: handle complete dimensions for monoblack/white. 
Fixes bug 269.
 2012-04-04 10:55:50 -07:00
Ronald S. Bultje 9487fb4dea swscale: clip unscaled output intermediates. 
Fixes bug 240, as well as several integer overflows (visible as glitches)
in other scaling output routines, e.g. YUV422.

Ronald S. Bultje 25c42234a9 swscale: make monowhite/black RGB-independent. 
Disadvantage is that it no longer allows modifying brightness through
adjustment of the RGB lookup table. Advantage is that now monowhite/black
no longer need to be identified as a RGB format.

Diego Biurrun 7331b6e718 Drop some completely unnecessary av_unused attributes. 2012-02-13 19:20:53 +01:00
Ronald S. Bultje 3cac475655 swscale: move YUV2PACKED16WRAPPER() macro down to where it is used. 2012-02-13 07:14:05 -08:00
Ronald S. Bultje c0b87359b2 swscale: handle gray16 as a "planar" YUV format (Y-only, of course). 
This allows removing any gray16-specific code, which is essentially
identical to the per-plane code in yuv2plane*().

Ronald S. Bultje d63b7d8c37 swscale: fix incorrect chroma bias in yuv2rgb48_1_c(). 2012-02-13 07:14:04 -08:00
Ronald S. Bultje 1ca7dc60d2 swscale: fix invalid memory accesses in yuvpacked1() functions. 2012-02-13 07:14:04 -08:00
Ronald S. Bultje 2144941069 swscale: split C output functions into separate file.
