+Subject: [PATCH] avcodec/rkmppdec: Fix double-free on error
+
+After having created the AVBuffer that is put into frame->buf[0],
+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.
