|\ | | | | | | | | | | | | | | | | | | | | | | | | * 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.

| | | | | | | | | | | | | | | | | | sws_getColorspaceDetails() Previously this would have lead to a memcpy(a,a) which violates the requirement of non overlapping src and dst. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
