Never assume the API of libav* to be stable unless at least 1 month has passed
since the last major version increase.
The last version increases were:
libavfilter: 2012-06-22
libavresample: 2012-04-24
API changes, most recent first:
2012-07-10 - 5fade8a - lavu 51.37.0
Add av_malloc_array() and av_mallocz_array()
2012-06-22 - d3d3a32 - lavu 51.34.0
2012-06-20 - ae0a301 - lavu 51.33.0
Move av_gettime() to libavutil, add libavutil/time.h
2012-06-09 - 3971be0 - lavr 0.0.3
Add a parameter to avresample_build_matrix() for Dolby/DPLII downmixing.

directly.

Add av_get_channel_layout_channel_index(), av_get_channel_name()
and av_channel_layout_extract_channel().
2012-05-25 - 154486f - lavu 51.31.0 - opt.h
2012-05-26 - e9cef89 - lavf 54.3.0

Add AVFMT_TS_NONSTRICT format flag to indicate that a muxer supports
non-increasing monotone timestamps.
2012-05-15 - lavfi 2.17.0
Add support for audio filters
ac71230/a2cd9be - add video/audio buffer sink in a new installed
header buffersink.h

av_vsrc_buffer_add_frame()

For audio formats with fixed frame size, the last frame
no longer needs to be padded with silence, libavcodec
will handle this internally (effectively all encoders
behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2012-02-01 - 316fc74 - lavc 54.01.0

f1caf01 Allow doing av_write_frame(ctx, NULL) for flushing possible
buffered data within a muxer. Added AVFMT_ALLOW_FLUSH for
muxers supporting it (av_write_frame makes sure it is called
only for muxers with this flag).

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.

AVFrame to AVFilterBufferRef.
