+Subject: [PATCH] avcodec/libsvtav1: unbreak build with latest svtav1
+
+SVT-AV1 made a change in their public API in 988e930c but without a
+version bump or any other accessible marker, thus breaking ffmpeg build
+with current versions of SVT-AV1.
+
+They have finally bumped versions a month later, so check added.
