Ronald S. Bultje baba2eedac swscale: extend mmx padding.
Fixes a crash when forcing libc to strictly adhere to malloc sizes.

Ronald S. Bultje 5c391a161a swscale: rename uv_off/uv_off2 to uv_off_px/byte. 2011-07-08 15:15:31 -07:00
Ronald S. Bultje 42d622fab3 swscale: fix 16-bit scaling when output is 8-bits.
We would use the second half of the U plane buffer, rather than the
V plane buffer, to output the V plane pixels.

Ronald S. Bultje 8f440223f6 swscale: disable full_chroma_int when converting to non-24/32bpp RGB.
This functionality is only implemented for RGB24/32 and causes crashes
otherwise.

Ronald S. Bultje 8a8d0ce208 swscale: for >8bit scaling, read in native bit-depth.
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.

Ronald S. Bultje ef1ee362b3 swscale: implement >8bit scaling support.
This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

Ronald S. Bultje dff5a83532 swscale: re-add support for non-native endianness.
This works through some non-obvious hacks in utils.c.

Ronald S. Bultje 6d4d483eee swscale: de-macro'ify RGB15/16/32 input functions.
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.

Ronald S. Bultje 808d8ff6bb swscale: allocate larger buffer to handle altivec overreads.
Altivec sws code intentionally overreads buffers for better performance,
so we need to allocate larger buffers to handle that.

Ronald S. Bultje 389e2000eb swscale: delay allocation of formatConvBuffer().
That means it won't be allocated when not needed. Alongside
this, it fixes valgrind/fate-detected memory leaks.

Ronald S. Bultje b4a224c5e4 swscale: split chroma buffers into separate U/V planes.
Preparatory step to implement support for sizes > VOFW.
2011-05-26 09:31:27 -04:00
Ronald S. Bultje 69645c021a swscale: replace formatConvBuffer[VOF] by allocated array.
This allows to convert between formats of arbitrary width,
regardless of the value of VOF/VOFW.

Diego Biurrun 046f081b46 configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.
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.

Ronald S. Bultje c8f487deae swscale: fix YUV420P 9/10bit support.
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.

Oskar Arvidsson 42239ced65 Add pixel formats for 9- and 10-bit yuv420p.
Also add support for these formats in libswscale.

Ramiro Polla 262b6dbad9 darwin: allow 64-bit darwin to allocate executable memory
darwin requires _DARWIN_C_SOURCE to be defined for MAP_ANON, which is used by
swscale to determine whether to use malloc() or mmap(). 64-bit darwin does not
have an executable heap, so mmap() must be used instead of malloc(), and
therefore _DARWIN_C_SOURCE must be defined.
