* swscale/utils: Use full chroma interpolation for rgb4/8 and dither noneMichael Niedermayer2021-07-09
| | | | | | | | Dither none is only implemented in full chroma interpolation for these rgb formats Its also a obscure choice (producing less nice images) that implementing it in the other code-paths makes no sense Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* sws: rename SwsContext.swscale to convert_unscaledAnton Khirnov2021-07-03
| | | | That function pointer is now used only for unscaled conversion.
* sws: separate the calls to scaled vs unscaled conversionAnton Khirnov2021-07-03
| | | | | | | | | | Call the scaler function directly rather than through a function pointer. Drop the now-unused return value from ff_getSwsFunc() and rename the function to reflect its new role. This will be useful in the following commits, where it will become important that the amount of output is different for scaled vs unscaled case.

* libswscale: Make sws_init_context thread safe.Peter Lundblad2021-07-01
| | | | | | | Call ff_sws_rgb2rgb_init via ff_thread_once instead of checking one of the variables it updates. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* swscale/utils: override forced-zero formats back to full rangeJan Ekström2020-10-11
| | | | | | | | Fixes vf_scale outputting RGB AVFrames with limited range flagged in case either input or output specifically sets the range. This is the reverse of the logic utilized for RGB and PAL8 content in sws_setColorspaceDetails.

* libswscale/utils.c: Fix bug #8255Gautam Ramakrishnan2020-02-09
| | | | | | | | | | Bug #8255 points out a double free error in libwscale/utils.c file. The double free is because the pointer to cascaded_context of an sw_context is not set to NULL after freeing it. When the sw_context is later freed, sws_freeContext is called on the cascaded_context, causing a double free. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* swscale: Add support for NV24 and NV42Philip Langdale2019-05-12
| | | | | | | | | | | The implementation is pretty straight-forward. Most of the existing NV12 codepaths work regardless of subsampling and are re-used as is. Where necessary I wrote the slightly different NV24 versions. Finally, the one thing that confused me for a long time was the asm specific x86 path that did an explicit exclusion check for NV12. I replaced that with a semi-planar check and also updated the equivalent PPC code, which Lauri kindly checked.

* swscale: Add p016 output support and generalise yuv420p1x to p010Philip Langdale2018-03-02
| | | | | | | | 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.
