2019-11-11libswcale: Fix possible string overflow in test.Adam Richter
In libswcale/tests/swcale.c, the function fileTest() calls sscanf in an argument of "%12s" on character srcStr[] and dstStr[], which are only 12 bytes. So, if the input string is 12 characters, a terminating null byte can be written past the end of these arrays. This bug was found by cppcheck.

2018-04-03avutil/pixdesc: deprecate AV_PIX_FMT_FLAG_PSEUDOPALwm4
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.
2018-03-31arm: swscale: Only compile the rgb2yuv asm if .dn aliases are supportedMartin Storsjö
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 d7320ca3ed10f0d, 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>

2018-03-03swscale: Add p016 output support and generalise yuv420p1x to p010Philip Langdale
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.
2017-11-13Fix missing used attribute for inline assembly variablesThomas Köppe
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. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

2017-10-25swscale: use dithering in DITHER_COPY only if not set -sws_dither noneMateusz
This patch uses dithering in DITHER_COPY macro only if it was not used option '-sws_dither none'. With option '-sws_dither none' it uses downshift. For human eye dithering is OK, for video codecs not necessarily. If user don't want to use dithering, we should respect that.

* 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>
