[FFmpeg-devel] [PATCH] swscale alpha channel support

[Cédric Schieli]

Hello,


Here is a splitted version of the patch.

#1 : sws_writebgr32_register_params.patch
makes mmx registers parametrized in the WRITEBGR32 macro

#2 : sws_split_yscale_macros.patch
splits various YSCALEYUV2xxx macros into YSCALEYUV2xxx_UV, YSCALEYUV2xxx_YA
and YSCALEYUV2xxx_COEFF

#3 : sws_dont_zero_alpha_channel.patch
moves zeroing of alpha channel register out of YSCALEYUV2xxx macros

#4 : sws_use_alpha.patch
main alpha patch

#5 : sws_use_alpha_reindent.patch
reindent after previous patch

Moreover, it now has been tested on both x86_32 and x86_64 systems.


Regards,
C?dric Schieli
