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.

Vittorio Giovara	6b3ff6f91a	swscale: provide a default scaler if none is set Lanczos for general case, sinc for upscaling, Gaussian for downscaling. According to current literature these scalers should be the best quality-wise algorithms for each case.

wm4	01e3340fb6	swscale: make bilinear scaling the default Before this commit, sws_init_context() failed with an error if no scaler was explicitly set. Defaulting to something reasonable is better behavior. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	aec91de549	swscale/utils: Allow sws_setColorspaceDetails() to use the tables from sws_getColorspaceDetails() Previously this would have lead to a memcpy(a,a) which violates the requirement of non overlapping src and dst.

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.
