* avcodec/x86/pngdsp: fix off by 1 errorMichael Niedermayer2014-12-081-1/+1
| | | | | | | | This fixes artifacts in the last pixel of rows with some widths and pixel formats Found-by: Dominique Leroux <Dominique.Leroux@autodesk.com> Tested-by: Dominique Leroux <Dominique.Leroux@autodesk.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* pngdsp x86: use unaligned accessChristophe Gisquet2014-12-031-6/+6
| | | | | | | | | | | | | | | | | | | | For test images manually generated to contain only up prediction, timing results: 8380x3032 255x185 before: 138635 1992 after: 139232 1996 Actually jumping to the proper version depending on the alignment: 8380x3032: 138767 A 0.5% speed improvement for gigantic images is not worth the code duplication.

* x86: yasm: Use complete source path for macro helper %includesDiego Biurrun2012-10-311-1/+1
| | | | | This is more consistent with the way we handle C #includes and it simplifies the build system.
* x86: include x86inc.asm in x86util.asmDiego Biurrun2012-10-311-1/+0
| | | | This is necessary to allow refactoring some x86util macros with cpuflags.
* x86: pngdsp: Fix assembly for OS/2Dave Yeo2012-08-081-1/+1
| | | | | | | The a.out object format does not allow aligning sections. On OS/2 LD aligns sections to 16 bytes. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* png: add support for bpp>4 to paeth x86 SIMD code.Ronald S. Bultje2012-01-291-1/+13
| | | | | This fixes playback of e.g. RGB48 (bpp=6) content on x86 CPUs. Fixes bug 214.
