* swscale: align vertical filtersize by 2 on x86.Ronald S. Bultje2011-11-05
| | | | | | The vertical scaler handles 2 rows at a time and thus requires alignment by 2, or else it'll read invalid memory and result in corrupt output.
* sws/pixfmt/pixdesc: add support for yuv420p9le/be.Ronald S. Bultje2011-10-21

* sws: support yuv444p9/10 output.Anton Khirnov2011-10-12
|
* swscale: fix byte overreads in SSE-optimized hscale().Ronald S. Bultje2011-09-15
| | | | | | SSE-optimized hScale() scales up to 4 pixels at once, so we need to allocate up to 3 padding pixels to prevent overreads. This fixes valgrind errors in various swscale-tests on fate.
* swscale: use 15-bit intermediates for 9/10-bit scaling.Ronald S. Bultje2011-08-12
|
* lsws: remove optimization debug logs in sws_init_context()Stefano Sabatini2011-08-05
| | | | | | | | | The logged information is possibly false, and it tends to be outdated after each change since the logging code needs to be manually updated. Simplify and prevent confusing wrong debug messages. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* lsws: use array for storing the supported in/out informationStefano Sabatini2011-08-05
| | | | | | | | | Also remove the unnecessary isSupportedIn/Out macros. Make the code more compact/readable, and simplify the access to lsws-specific pixel format information. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* Revert "swscale: use 15-bit intermediates for 9/10-bit scaling."Ronald S. Bultje2011-08-02
| | | | | | This reverts commit ac0fb5934893be554a44d2a1eb7a3bc7bf39da4a. It causes valgrind errors which I'll want to investigate before resubmitting this.

* swscale: extend mmx padding.Ronald S. Bultje2011-07-14
| | | | Fixes a crash when forcing libc to strictly adhere to malloc sizes.
* doxygen: Make sure parameter names match between .c and .h files.Diego Biurrun2011-07-14

* swscale: rename uv_off/uv_off2 to uv_off_px/byte.Ronald S. Bultje2011-07-08
|
* swscale: fix 16-bit scaling when output is 8-bits.Ronald S. Bultje2011-07-08
| | | | | We would use the second half of the U plane buffer, rather than the V plane buffer, to output the V plane pixels.
* swscale: disable full_chroma_int when converting to non-24/32bpp RGB.Ronald S. Bultje2011-07-02
| | | | | This functionality is only implemented for RGB24/32 and causes crashes otherwise.
* swscale: for >8bit scaling, read in native bit-depth.Ronald S. Bultje2011-07-01
| | | | | | For 9/10bit, it means we don't have to upscale to 16bit before actual scaling or pixel format conversion, and thus a performance gain.
* swscale: implement >8bit scaling support.Ronald S. Bultje2011-06-29
| | | | | | This means that precision is retained when scaling between sample formats with >8 bits per component (48bit RGB, 16bit grayscale, 9/10/16bit YUV).
* swscale: re-add support for non-native endianness.Ronald S. Bultje2011-06-27
| | | | This works through some non-obvious hacks in utils.c.
* swscale: use SwsContext for av_log when availableJanne Grunau2011-06-15

* libavutil/swscale: YUV444P10/YUV444P9 support.Ronald S. Bultje2011-06-10
| | | | | | | Also add missing glue code for recently added YUV422P10 formats to swscale. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* swscale: de-macro'ify RGB15/16/32 input functions.Ronald S. Bultje2011-06-09
| | | | | | | | Inline functions are easier to read, maintain, modify and test, which justifies the slightly increased source size. This patch also adds support for non-native endianness RGB15/16 and fixes isSupportedOutput() to no longer claim that we support writing non-native RGB565/555/444.
* swscale: allocate larger buffer to handle altivec overreads.Ronald S. Bultje2011-06-02
| | | | | Altivec sws code intentionally overreads buffers for better performance, so we need to allocate larger buffers to handle that.
* swscale: fix crash in bilinear scaling.Ronald S. Bultje2011-05-28
|
* swscale: delay allocation of formatConvBuffer().Ronald S. Bultje2011-05-27
| | | | | That means it won't be allocated when not needed. Alongside this, it fixes valgrind/fate-detected memory leaks.
* swscale: remove VOF/VOFW.Ronald S. Bultje2011-05-26
|
* swscale: split chroma buffers into separate U/V planes.Ronald S. Bultje2011-05-26
| | | | Preparatory step to implement support for sizes > VOFW.
* swscale: replace formatConvBuffer[VOF] by allocated array.Ronald S. Bultje2011-05-26
| | | | | This allows to convert between formats of arbitrary width, regardless of the value of VOF/VOFW.
* swscale: Remove commented-out printf cruft.Diego Biurrun2011-05-26

* configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.Diego Biurrun2011-05-12
| | | | | | | | | | | | | | | | Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.
* swscale: fix YUV420P 9/10bit support.Ronald S. Bultje2011-05-11
| | | | | | | Fix handling of input if not in native endianness, and add support for 9/10-bit output. This allows us to force endianness of YUV420P 9/10bit in the H264/10bit fate tests, which should fix them on big-endian systems.
* Add pixel formats for 9- and 10-bit yuv420p.Oskar Arvidsson2011-05-10
| | | | | | | | Also add support for these formats in libswscale. Needed for high bit depth h264 decoding. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
