 API changes, most recent first:

+2013-03-xx - Reference counted buffers - lavu 52.8.0, lavc 55.0.0, lavf 55.0.0,

+lavd 54.0.0, lavfi 3.5.0

+  xxxxxxx, xxxxxxx - add a new API for reference counted buffers and buffer

+                     pools (new header libavutil/buffer.h).

+  xxxxxxx - add AVPacket.buf to allow reference counting for the AVPacket data.

+            Add av_packet_from_data() function for constructing packets from

+            av_malloc()ed data.

+  xxxxxxx - move AVFrame from lavc to lavu (new header libavutil/frame.h), add

+            AVFrame.buf/extended_buf to allow reference counting for the AVFrame

+            data. Add new API for working with reference-counted AVFrames.

+  xxxxxxx - add the refcounted_frames field to AVCodecContext to make audio and

+            video decoders return reference-counted frames. Add get_buffer2()

+            callback to AVCodecContext which allocates reference-counted frames.

+            Add avcodec_default_get_buffer2() as the default get_buffer2()

+            implementation.

+            Deprecate AVCodecContext.get_buffer() / release_buffer() /

+            reget_buffer(), avcodec_default_get_buffer(),

+            avcodec_default_reget_buffer(), avcodec_default_release_buffer().

+            Remove avcodec_default_free_buffers(), which should not have ever

+            been called from outside of lavc.

+            Deprecate the following AVFrame fields:

+                * base -- is now stored in AVBufferRef

+                * reference, type, buffer_hints -- are unnecessary in the new API

+                * hwaccel_picture_private, owner, thread_opaque -- should not

+                  have been acessed from outside of lavc

+                * qscale_table, qstride, qscale_type, mbskip_table, motion_val,

+                  mb_type, dct_coeff, ref_index -- mpegvideo-specific tables,

+                  which are not exported anymore.

+  xxxxxxx - switch libavfilter to use AVFrame instead of AVFilterBufferRef. Add

+            av_buffersrc_add_frame(), deprecate av_buffersrc_buffer().

+            Add av_buffersink_get_frame() and av_buffersink_get_samples(),

+            deprecate av_buffersink_read() and av_buffersink_read_samples().

+            Deprecate AVFilterBufferRef and all functions for working with it.

+

 2013-xx-xx - xxxxxxx - lavu 52.8.0 - avstring.h

   Add av_isdigit, av_isgraph, av_isspace, av_isxdigit.
