+  Deprecate that demuxers export the stream rotation angle in AVStream.metadata
+  (via an entry named "rotate"). Use av_stream_get_side_data() with
+  AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
+  av_display_rotation_get(). The same is done for muxing. Instead of adding a
+  "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
+  to be added to the AVStream.

   vdpau hardware accelerated decoding now supports the new hwaccel API, which
   can create the decoder context and allocate hardware frame automatically.
