Michael Niedermayer	7e3a070d9a	Bump minor versions for branching release/4.0 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	2018-04-16 12:35:12 +02:00
wm4	d6fc031caf	avutil/pixdesc: deprecate AV_PIX_FMT_FLAG_PSEUDOPAL PSEUDOPAL pixel formats are not paletted, but carried a palette with the intention of allowing code to treat unpaletted formats as paletted. The palette simply mapped the byte values to the resulting RGB values, making it some sort of LUT for RGB conversion. It was used for 1 byte formats only: RGB4_BYTE, BGR4_BYTE, RGB8, BGR8, GRAY8. The first 4 are awfully obscure, used only by some ancient bitmap formats. The last one, GRAY8, is more common, but its treatment is grossly incorrect. It considers full range GRAY8 only, so GRAY8 coming from typical Y video planes was not mapped to the correct RGB values. This cannot be fixed, because AVFrame.color_range can be freely changed at runtime, and there is nothing to ensure the pseudo palette is updated. Also, nothing actually used the PSEUDOPAL palette data, except xwdenc (trivially changed in the previous commit). All other code had to treat it as a special case, just to ignore or to propagate palette data. In conclusion, this was just a very strange old mechnaism that has no real justification to exist anymore (although it may have been nice and useful in the past). Now it's an artifact that makes the API harder to use: API users who allocate their own pixel data have to be aware that they need to allocate the palette, or FFmpeg will crash on them in _some_ situations. On top of this, there was no API to allocate the pseuo palette outside of av_frame_get_buffer(). This patch not only deprecates AV_PIX_FMT_FLAG_PSEUDOPAL, but also makes the pseudo palette optional. Nothing accesses it anymore, though if it's set, it's propagated. It's still allocated and initialized for compatibility with API users that rely on this feature. But new API users do not need to allocate it. This was an explicit goal of this patch. Most changes replace AV_PIX_FMT_FLAG_PSEUDOPAL with FF_PSEUDOPAL. I first tried #ifdefing all code, but it was a mess. The FF_PSEUDOPAL macro reduces the mess, and still allows defining FF_API_PSEUDOPAL to 0. Passes FATE with FF_API_PSEUDOPAL enabled and disabled. In addition, FATE passes with FF_API_PSEUDOPAL set to 1, but with allocation functions manually changed to not allocating a palette.	2018-04-03 17:53:00 +02:00
Martin Storsjö	f33f728470	arm: swscale: Only compile the rgb2yuv asm if .dn aliases are supported Vanilla clang supports altmacro since clang 5.0, and thus doesn't require gas-preprocessor for building the arm assembly any longer. However, the built-in assembler doesn't support .dn directives. This readds checks that were removed in `d7320ca3ed`, when the last usage of .dn directives within libav were removed. Alternatively, the assembly could be rewritten to not use the .dn directive, making it available to clang users. Signed-off-by: Martin Storsjö <martin@martin.st>	2018-03-31 21:54:56 +03:00

Philip Langdale	9d5aff09a7	swscale: Add p016 output support and generalise yuv420p1x to p010 To make the best use of existing code, I generalised the wrapper that currently does yuv420p10 to p010 to support any mixture of input and output sizes between 10 and 16 bits. This had the side effect of yielding a working code path for all yuv420p1x formats to p01x.	2018-03-02 14:52:48 -08:00
Thomas Köppe	43171a2a73	Fix missing used attribute for inline assembly variables Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO.

James Almer	69b5ce64d2	Merge commit '07a2b155949eb267cdfc7805f42c7b3375f9c7c5' * commit '07a2b155949eb267cdfc7805f42c7b3375f9c7c5': Bump major versions of all libraries A few API deprecated ~2 years ago or more are also postponed here for varying reasons. FF_API_LOWRES: Since this functionality depends on AVStream->codec, i figure the two can be removed at the same time in the next bump or so. FF_API_AVCTX_TIMEBASE: Couldn't get this one to work. Not just libavcodec but apparently also libavformat and ffmpeg.c expect AVCodecContext->time_base to be set for decoding. Upon removal some tests report a different generic stream time base (like 1/25), and others lose packet duration values. I guess it's somehow tied to the AVStream->codec clusterfuck. It can be dealt with alongside FF_API_LAVF_AVCTX in the next bump. FF_API_OLD_FILTER_OPTS_ERROR: This one is meant to remain after FF_API_OLD_FILTER_OPTS is removed. Its purpose is displaying the corrected command line using the new syntax as a suggestion as part of the error message. Merged-by: James Almer <jamrial@gmail.com>	2017-10-21 14:57:53 -03:00

Øyvind Kolås	3e6016622e	swscale: add two spatially stable dithering methods Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for GIF they can be considered better than bayer (provides more gray-levels), and spatial stability - often more than twice as good compression and less visual flicker than error diffusion methods (the methods also avoids error-shadow artifacts of diffusion dithers). These methods are similar to blue/green noise type dither masks; but are simple enough to generate their mask on the fly. They are still research work in progress; though more expensive to generate masks (which can be used in a LUT) like 'void and cluster' and similar methods will yield superior results	2014-03-25 13:48:06 +01:00
