Michael Niedermayer	5e947aeb59	sws/x86: improve rounding for yuv2yuvX This tries to compensate for the errors introduced by the rounding of pmulhw Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Martin Storsjö	d192ac3e03	swscale: Disallow conversion to GBRP16 This reverts parts of `d6d5ef5534`, 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.

Michael Niedermayer	02001a372d	sws: add planar RGB formats to isAnyRGB We have to make some symetric changes elsewhere as this increases the precission with which samples are stored. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Diego Biurrun	ef5d41a553	x86inc: Rename "program_name" to "private_prefix" 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>	12 years ago
Xi Wang	f73f76fd20	swscale: fix NULL checking in sws_alloc_context() 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.

Stefano Sabatini	605f1d9865	lsws: define version in SWScaler class The version number is useful to check the libavutil version against which the library was compiled at run-time, which in turn may be useful to deal with binary compatibility issues.	12 years ago

Kostya Shishkov	38fdf72580	swscale: do not forget to swap data in formats with different endianness 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.
