From 081b35c5b598fef0a2e47753752f7607ff90a2d3 Mon Sep 17 00:00:00 2001
From: Neal Gompa <ngompa@fedoraproject.org>
Date: Fri, 18 Feb 2022 08:12:54 -0500
Subject: [PATCH] avcodec/openh264: Add the ability to dlopen() OpenH264
We can't directly depend on OpenH264, but we can weakly link to it
and gracefully expose the capability.
