Subject: [FFmpeg-devel] [PATCH] avutil/cpu: #define _GNU_SOURCE before including any standard headers
Date: Thu, 14 Apr 2022 23:20:43 +0200
Message-ID: <20220414212043.25953-1-cus@passwd.hu> (raw)
Otherwise its effect might not work causing CPU_COUNT to not get defined.
Fixes cpu count detection to actually use sched_getaffinity if available.
