Vittorio Giovara	2257165bff	png: disable broken MMX/SIMD code for bpp <= 2 The decoder was producing different results when ASM was disabled. 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
