* lsws/utils: fix typoStefano Sabatini2013-11-051-1/+1

* Optimize pure C unscaled yuv2rgb.Reimar Döffinger2013-10-301-1/+3
| | | | | | | | | | | 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. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

|\ | | | | | | | | | | | | | | | | | | | | | | | | * commit '6b3ff6f91a535d6383f41ca7bdf760165dcb6015': swscale: provide a default scaler if none is set Conflicts: libswscale/utils.c The default is left at bicubic until someone has compared the scalers properly speed and quality wise. Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * swscale: provide a default scaler if none is setVittorio Giovara2013-10-051-1/+11
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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>
