Vittorio Giovara	fc1eda543c	swscale: fix sign extensions in yuv planar conversion Casting the left-most byte to unsigned avoids an undefined result of the shift by 24 if bit 7 is set. yuvPlanartouyvy_c and yuvPlanartoyuy2_c are affected. CC: libav-stable@libav.org Bug-Id: CID 732281 / CID 732282	10 years ago

Vitor Sessak	55d11d277b	swscale/x86: do not expect registers to be preserved across inline ASM blocks Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Clément Bœsch	d469aa8cfa	sws: use av_clip() instead of av_clip_c()	10 years ago
James Almer	9ffac3d00d	lsws: duplicate ff_log2_tab libswscale uses the table but wasn't duplicating it like the rest of the libs. This should fix compilation failures on msvc/icl after lavu stopped exporting internal functions and tables.

Vittorio Giovara	f84a1b597c	swscale: support AV_PIX_FMT_YA16 as input Based on a long debug session with Kostya.	11 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.	11 years ago
