* swscale: Properly scale YUVDerek Buitenhuis2014-12-05
| | | | | | | | | | Only shift limited range luma, and always only shift chroma for upconversion. Based off a patch by Michael Niedermayer. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* swscale: support AV_PIX_FMT_YA16 as inputVittorio Giovara2014-08-04
| | | | Based on a long debug session with Kostya.
* avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara2014-08-04
| | | | | | | 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.
* swscale: correctly pad destination buffer in rgb conversionKostya Shishkov2014-08-04

* Remove all Blackfin architecture optimizationsDiego Biurrun2014-06-02
| | | | | | Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.
* swscale: Set alpha to opaque for internal palettes.Justin Ruggles2014-04-12
| | | | | | | | | Fixes conversion of pal8 to rgb formats with alpha. Updated references for 2 FATE tests which previously encoded fully transparent images. Based on a patch by Baptiste Coudurier <baptiste.coudurier@gmail.com>

* swscale: fix invalid conversions and memory problems.Ronald S. Bultje2012-01-12
| | | | | | | | | | Fixes problems where rgbToRgbWrapper() is called even though it doesn't support this particular conversion (e.g. converting from RGB444 to anything). Thirdly, fixes issues where rgbToRgbWrapper() is called for non-native endiannness conversions (e.g. RGB555BE on a LE system). Fourthly, fixes crashes when converting from e.g. monowhite to monowhite, which calls planarCopyWrapper() and overwrites/reads because n_bytes != n_pixels.

* swscale: prevent invalid writes in packed_16bpc_bswapJanne Grunau2011-12-26
| | | | | Writes past the end of the destination buffer were occuring when its stride was smaller than the stride of the source. Fixes Bug #183.

* swscale: Fix stack alignment for SSEJohn Stebbins2011-11-19
| | | | | | | | Although gcc guarantees 16 byte stack alignment, threads under WinXP don't appear to be guaranteed to start stack aligned. So fix the alignment. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Do not convert RGB buffer at once when stride does not fit exact samples.Kostya Shishkov2011-07-30
| | | | | | | | | | | When converting RGB format to RGB format with the same bits per sample, unscaled path performs conversion on the whole buffer at once. For non-multiple-of-16 BGR24 to RGB24 conversion it means that padding at the end of line will be converted too. Since it may be of arbitrary length (e.g. 8 bytes), operating on the whole buffer produces obviously wrong results. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* swscale: clip unscaled colorspace conversion path.Ronald S. Bultje2011-07-14
| | | | | Prevents overflows on very bright scenes when adding dither, which may lead to black dots.

* swscale: implement error dithering in planarCopyWrapper.Ronald S. Bultje2011-07-08

* swscale: split swscale.c in unscaled and generic conversion routines.Ronald S. Bultje2011-06-03
This duplicates the function fillPlane().
