* swscale: Kill non-compiling disabled cruftDiego Biurrun2016-08-171-6/+0
|
* swscale: Rename sws_context_class to ff_sws_context_classAndreas Cadhalpun2016-07-161-1/+1
| | | | | | | It is an internal swscale symbol and thus should not be exported. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>
* cosmetics: Fix spelling mistakesVittorio Giovara2016-05-041-58/+58

* lavu: Drop the {minus,plus}1 suffix from AVComponentDescriptor fieldsVittorio Giovara2015-09-071-2/+2
| | | | | | The new fields can be accessed directly and are more intelligible. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* libswscale: GBRAP input & output and GBRAP16 input supportPaul B Mahol2015-01-141-1/+2
| | | | Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* swscale: support AV_PIX_FMT_YA16 as inputVittorio Giovara2014-08-041-1/+3
| | | | Based on a long debug session with Kostya.
* avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara2014-08-041-2/+2
| | | | | | | 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.
* Remove all Blackfin architecture optimizationsDiego Biurrun2014-06-021-16/+0
| | | | | | 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.
* RGBA64 pixel formatsJean First2014-03-161-0/+4
| | | | Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* Remove all SPARC architecture optimizationsDiego Biurrun2014-03-131-5/+0
| | | | | SPARC is no longer being used in any multimedia-related fields and the VIS optimizations only represent a maintenance burden.
* swscale: cosmetics: Drop silly camelCase from swScale function pointer nameDiego Biurrun2013-08-291-3/+3
|
* swscale: consistent names for arch-specific acceleration functionsDiego Biurrun2013-08-291-4/+3
|
* swscale: ppc: Hide arch-specific initialization detailsDiego Biurrun2013-08-291-5/+5
| | | | Also give consistent names to init functions.
* swscale: x86: Hide arch-specific initialization detailsDiego Biurrun2013-08-281-2/+2
| | | | Also give consistent names to init functions.

* swscale: make filterPos 32bit.Ronald S. Bultje2012-03-061-6/+6
| | | | | | | Fixes overflows for large image sizes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* Revert two swscale commits.Ronald S. Bultje2012-02-191-4/+6
| | | | | | | | | | | Revert "swscale: update context offsets after removal of AlpMmxFilter." (commit a95e3fa90b4190381b65d180eec5a4027075e2da) and Revert "swscale: Remove some write-only variables related to alpha handling." (commit 9d03cb9fc5ddf914920ab0dbe13f19a34c754966). They broke alpha handling - it's the evil inline asm that still uses that variable, so it's not truely write-only.
* swscale: update context offsets after removal of AlpMmxFilter.Ronald S. Bultje2012-02-171-5/+4
|
* swscale: Remove some write-only variables related to alpha handling.Diego Biurrun2012-02-141-1/+0
|
* pixdesc: mark pseudopaletted formats with a special flag.Anton Khirnov2012-02-081-1/+3
| | | | | | This makes it possible to dintinguish them from PAL8. Fixes an invalid write in avpicture_layout().
* Remove Sun medialib glue code.Diego Biurrun2012-02-081-1/+0
| | | | | It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.
* swscale: split C output functions into separate file.Ronald S. Bultje2012-02-071-0/+7

|
* swscale: fix failing fate tests.Ronald S. Bultje2011-11-241-0/+9
| | | | isGray() is left as a FIXME for later.
* swscale: add support for planar RGB input.Ronald S. Bultje2011-11-241-0/+14

* Clean up swscale pixfmt macros using av_pix_fmt_descriptors[].Ronald S. Bultje2011-11-241-106/+34

* Split out yuv2yuv1 luma and chroma in order to make them generic DSP functionsKieran Kunhya2011-10-221-16/+10
| | | | Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* sws/pixfmt/pixdesc: add support for yuv420p9le/be.Ronald S. Bultje2011-10-211-0/+4
|
* swscale: split hScale() function pointer into h[cy]Scale().Ronald S. Bultje2011-08-171-3/+8
| | | | | | This allows using more specific implementations for chroma/luma, e.g. we can make assumptions on filterSize being constant, thus avoiding that test at runtime.
* swscale: use 15-bit intermediates for 9/10-bit scaling.Ronald S. Bultje2011-08-121-45/+63
|
* Revert "swscale: use 15-bit intermediates for 9/10-bit scaling."Ronald S. Bultje2011-08-021-50/+25
| | | | | | This reverts commit ac0fb5934893be554a44d2a1eb7a3bc7bf39da4a. It causes valgrind errors which I'll want to investigate before resubmitting this.
* swscale: use 15-bit intermediates for 9/10-bit scaling.Ronald S. Bultje2011-08-021-25/+50
|
* swscale: fix crash with dithering due incorrect offset calculation.Anton Mitrofanov2011-07-101-2/+5
| | | | | | | | ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte aligned and thus at a different offset than intended. Forcing 8-byte alignment forces equal offset of dither16/32 on x86-32 and x86-64. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* swscale: rename uv_off/uv_off2 to uv_off_px/byte.Ronald S. Bultje2011-07-081-4/+4
|
* swscale: error dithering for 16/9/10-bit to 8-bit.Ronald S. Bultje2011-07-081-0/+6
| | | | Based on a somewhat similar idea in FFmpeg's swscale copy.
* swscale: amend documentation to mention use of native depth for scaling.Ronald S. Bultje2011-07-061-1/+4
