-Subject: PATCH 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 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.

+
+After having created the AVBuffer that is put into frame->buf0,
+ownership of several objects (namely an AVDRMFrameDescriptor,
+an MppFrame and some AVBufferRefs framecontextref and decoder_ref)
+has passed to the AVBuffer and therefore to the frame.
+Yet it has nevertheless been freed manually on error
+afterwards, which would lead to a double-free as soon
