Pedro Arthur	5bd62a1b3c	swscale: fix ticket #4881 When scaling only a slice of a frame the output was written always in the first lines leaving the rest of the frame black.	9 years ago
Michael Niedermayer	d730dd8c53	swscale: Forward colorspace updates to the 2nd cascaded context in case of alphablend The first just does the blending and wouldnt do anything with the colorspace values Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago
Vittorio Giovara	2268db2cd0	lavu: Drop the {minus,plus}1 suffix from AVComponentDescriptor fields The new fields can be accessed directly and are more intelligible. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago

Vittorio Giovara	f84a1b597c	swscale: support AV_PIX_FMT_YA16 as input Based on a long debug session with Kostya.	10 years ago
Vittorio Giovara	e96c3b81ca	avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8 The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.	10 years ago

Derek Buitenhuis	a4bd4733c0	swscale: Allow the max filter size to be set at compile time This can help "extreme" resizes, e.g with some 4k stuff. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Diego Biurrun	880e2aa236	Remove all Blackfin architecture optimizations Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.	11 years ago

Øyvind Kolås	3e6016622e	swscale: add two spatially stable dithering methods Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for GIF they can be considered better than bayer (provides more gray-levels), and spatial stability - often more than twice as good compression and less visual flicker than error diffusion methods (the methods also avoids error-shadow artifacts of diffusion dithers). These methods are similar to blue/green noise type dither masks; but are simple enough to generate their mask on the fly. They are still research work in progress; though more expensive to generate masks (which can be used in a LUT) like 'void and cluster' and similar methods will yield superior results	11 years ago

Diego Biurrun	b4dd424d96	Remove all SPARC architecture optimizations SPARC is no longer being used in any multimedia-related fields and the VIS optimizations only represent a maintenance burden.	11 years ago

Reimar Döffinger	4fab08c94f	Optimize pure C unscaled yuv2rgb. Aligning the tables reduces the amount of code generated on e.g. ARM as the offset constant then has few enough set bits so it can be encoded inside a single instruction instead of 2. Ideally all should be declared aligned, but the DECLARE_ALIGNED macros does not work with pointer tables, thus also reordered the tables.

Michael Niedermayer	c62801270f	swscale: change ff_dither_8x8_128 dimensions to be consistent with the others Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	1e0e193240	sws: add dither enum This allows specifying more dither algorithms without using up flags and without ambiguities. Also initialize the new field based on the flags and use it. Note, improving the logic of the checks is left to subsequent commits, this here only switches from flags to enum.
