* lavfi/drawutils: improve colorspace supportrcombs2022-06-19
| | | | | | | | | | | | | | | | | | | | | - Introduce ff_draw_init2, which takes explicit colorspace and range args - Use lavu/csp and lavfi/colorspace for conversion, rather than the lavu/colorspace.h macros - Use the passed-in colorspace when performing RGB->YUV conversions The upshot of this is: - Support for YUV spaces other than BT601 - Better rounding for all conversions - Particular rounding improvements in >8-bit formats, which previously used simple left-shifts - Support for limited-range RGB - Support for full-range YUV in non-J pixfmts Due to the rounding improvements, this results in a large number of minor changes to FATE tests.

* lavfi/drawutils: overhaul to improve pixel format supportrcombs2022-01-04
| | | | | | | | | | | | - No longer mixes u8 and u16 component accesses (this was UB) - De-duplicated 8->16 conversion - De-duplicated component -> plane+offset conversion - De-duplicated planar + packed RGB - No longer calls ff_fill_rgba_map - Removed redundant comp_mask data member - RGB0 and related formats no longer write an alpha value to the 0 byte - Non-planar YA formats now work correctly - High-bit-depth semi-planar YUV now works correctly

* avutil/pixdesc: deprecate AV_PIX_FMT_FLAG_PSEUDOPALwm42018-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* avfilter/all: propagate errors of functions from avfilter/formatsGanesh Ajjanagadde2015-10-14
| | | | | | | | | | | | | | | | | | Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.
