-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.

-Subject: PATCH avcodec/rkmppdec: Fix double-free on error
-
-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
-as the AVFrame is unreferenced.
