* swscale/output: Don't call av_pix_fmt_desc_get() in a loopAndreas Rheinhardt2022-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, libswscale/output.c used a macro to write an output pixel which involved a call to av_pix_fmt_desc_get() to find out whether the input pixel format is BE or LE despite this being known at compile-time (there are templates per pixfmt). Even worse, these calls are made in a loop, so that e.g. there are eight calls to av_pix_fmt_desc_get() for every pixel processed in yuv2rgba64_X_c_template() for 64bit RGB formats. This commit modifies these macros to ensure that isBE() is evaluated at compile-time. This saved 41184B of .text for me (GCC 11.2, -O3). Of course, it also improved performance. E.g. ffmpeg_g -f lavfi -i testsrc2,format=yuva420p -pix_fmt rgba64le \ -threads 1 -t 1:00 -f null - (which uses yuv2rgba64le_X_c, which is an invocation of yuv2rgba64_X_c_template() mentioned above), performance improved from 95589 to 41387 decicycles for one call to yuv2packedX; for the be variant the numbers went down from 76087 to 43024 decicycles.

| | | | | | As we already have support for VUYA, I figured I should do the small amount of work to support VUYX as well. That means a little refactoring to share code.

* 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.
