2013-10-05 | swscale: provide a default scaler if none is set | Vittorio Giovara | |
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. Inspired from a patch by wm4 <nfxjfg@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org> | |||

2013-05-06 | swscale: Use alpha from the right row in yuva2rgba_c | Martin Storsjö | |

2013-02-27 | swscale: Add support for unscaled 8-bit Packed RGB -> Planar RGB | Derek Buitenhuis | |

2013-02-11 | swscale: Disallow conversion to GBRP16 | Martin Storsjö | |
This reverts parts of d6d5ef5534d582, that didn't work right. (The tests that were added failed on big endian, and the output looked garbled on little endian as well.) This is due to the fact that the intermediate scaling values (from e.g. hScale8To19_c or hScale16To19_c) are stored as int32_t and thus requires a separate output function, while yuv2gbrp_full_X_c only interprets it as int16_t.

2013-01-18 | x86inc: Rename "program_name" to "private_prefix" | Diego Biurrun | |
The new name is more descriptive and will allow defining a separate public prefix for externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de> | |||
2013-01-05 | swscale: fix NULL checking in sws_alloc_context() | Xi Wang | |
sws_getCachedContext() and sws_getContext() expect sws_alloc_context() to return NULL when out of memory, as follows. if (!(context = sws_alloc_context())) return NULL; This patch fixes sws_alloc_context() to return NULL in that case.

2012-11-16 | libswscale: remove unnecessary direct #if LIBSWSCALE_VERSION_MAJOR | Janne Grunau | |
SWS_CPU_CAPS are deprecated and slated to removed with libswscale major version 3. No need to provide a SWS_CPU_CAPS_MMX2 as backward compatibility define under the same explicit condition. | |||

2012-10-31 | swscale: do not forget to swap data in formats with different endianness | Kostya Shishkov | |
Otherwise during scaling it will try to interpret input in the wrong way and that leads to the test results disagreeing on different platforms and with different optimizations. Signed-off-by: Diego Biurrun <diego@biurrun.de> | |||

2012-10-31 | x86: yasm: Use complete source path for macro helper %includes | Diego Biurrun | |
This is more consistent with the way we handle C #includes and it simplifies the build system. | |||
2012-10-31 | x86: include x86inc.asm in x86util.asm | Diego Biurrun | |
This is necessary to allow refactoring some x86util macros with cpuflags. | |||

2012-10-23 | swscale: avoid pointless use of compound literals | Mans Rullgard | |
Some compilers (e.g. old gcc) have trouble with these. Signed-off-by: Mans Rullgard <mans@mansr.com> | |||
2012-10-15 | swscale: try to use mmap only if available | Mans Rullgard | |
Some systems, e.g. Minix, have sys/mman.h defining MAP_ANONYMOUS without providing (working) mmap and friends. The mmx filter generation code checks only for MAP_ANONYMOUS, not for availability of mmap itself which leads to build errors on aforementioned systems. This changes the conditional compilation to use mmap only if all the required functions are available. Signed-off-by: Mans Rullgard <mans@mansr.com> |
