 %description
-dav1d is a new AV1 cross-platform Decoder, open-source, and focused on speed
-and correctness.
+dav1d is a SIMD-enhanced decoder for AV1 video. It features
+
+ * Accelerated assembly using x86 AVX2.
+ * Partial acceleration using x86 SSSE3 and ARM NEON.
+ * Support for bitdepths 8, 10 and 12.
+ * Support for chroma subsamplings 4:2:0, 4:2:2, 4:4:4 and grayscale.
+
+AV1 is a royalty-free video codec by the Alliance for Open Media. It
+has the potential to be up to 20%% better than the HEVC codec.
+dav1d outperforms gav1 by about 20%% on ARM and 50%% on x86,
+and has better scaling properties for larger thread counts.
