+- optimal_buffer_level_ms (--buf-optimal-sz)
+
+and vbv_bufsize has not been in use since svt-av1 v0.8.6

+Subject: [PATCH 2/4] avcodec/libsvtav1: remove compressed_ten_bit_format and
+ simplify alloc_buffer
+
+compressed_ten_bit_format has been deprecated upstream and has no effect
+and can be removed. Plus, technically it was never used in the first place
+since it would require the app (ffmpeg) to set it and do additional
+processing of the input frames.
+
+Also simplify alloc_buffer by removing calculations relating to the
+non-existant processing.

+Subject: [PATCH 4/4] avcodec/libsvtav1: use larger of bit rate and max rate
+ for buffer size
+
+Generally if maxrate is set, the calculation should be maxrate over
+bufsize. This additionally enables CRF + maxrate & bufsize usage.
+
+In order to keep negative values from enabling zero to be treated
+as larger and causing a division by zero, check that one of the
+variables is larger than zero.
