Subject: [FFmpeg-devel] [PATCH 2/2] swscale/input: Avoid calls to av_pix_fmt_desc_get()
Date: Thu, 8 Sep 2022 04:38:11 +0200
Message-ID: <GV1P250MB0737CDE238A6D1F2FB8A9F4E8F409@GV1P250MB0737.EURP250.PROD.OUTLOOK.COM> (raw)
In-Reply-To: <GV1P250MB07370A2874066BF522C7670A8F409@GV1P250MB0737.EURP250.PROD.OUTLOOK.COM>
Up until now, libswscale/input.c used a macro to read
an input 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 six calls to av_pix_fmt_desc_get()
for every pair of UV pixel processed in
rgb64ToUV_half_c_template().
This commit modifies these macros to ensure that isBE()
is evaluated at compile-time. This saved 9743B of .text
for me (GCC 11.2, -O3).

output.c suffers from the same issue (and according to coverage
is responsible for quite a large chunk of the calls to
av_pix_fmt_desc_get() (144699832 of 321342234)), so I will
be looking into this tomorrow.
