From 044a7c08dc7ef565786fdc87a35298033bb0ef02 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sat, 18 Sep 2021 05:33:25 +0200 Subject: [PATCH] swscale/swscale: Disable x86-specific code for other arches SSE2 is x86 specific, yet due to the call to av_get_cpu_flags() compilers were unable to optimize the checks (and the call) away on other arches.
