+ Add av_popcount64
+
+2011-12-25 - lavfi 2.14.0
+ e1d9dbf Add a new installed header - buffersrc.h
+ It contains a new function av_buffersrc_buffer() that allows passing
+ frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
+ it allows for direct rendering.
+ 1c9e340 Add avfilter_copy_frame_props() for copying properties from
+ AVFrame to AVFilterBufferRef.
+
+2011-12-25 - lavc 53.31.0
+ Add the following new fields to AVFrame:
+ b58dbb5 sample_aspect_ratio
+ 3a2ddf7 width, height
+ 8a4a5f6 format
+
+2011-12-18 - 8400b12 - lavc 53.28.1
+ Deprecate AVFrame.age. The field is unused.
