API changes, most recent first:

16 17 18 19 20
2012-10-xx - xxxxxxx - lavr 1.0.0 - avresample.h
  Data planes parameters to avresample_convert() and
  avresample_read() are now uint8_t** instead of void**.
  Libavresample is now stable.

21 22 23 24
2012-09-23 - xxxxxxx - lavc 54.28.0 - avcodec.h
  Add avcodec_free_frame(). This function must now
  be used for freeing an AVFrame.

25 26 27
2012-09-12 - xxxxxxx - lavu 51.41.0 - audioconvert.h
  Added AV_CH_LOW_FREQUENCY_2 channel mask value.

28 29 30 31
2012-09-04 - xxxxxxx - lavu 51.40.0 - opt.h
  Reordered the fields in default_val in AVOption, changed which
  default_val field is used for which AVOptionType.

32 33 34 35
2012-xx-xx - xxxxxxx - lavc 54.26.1 - avcodec.h
  Add codec descriptor properties AV_CODEC_PROP_LOSSY and
  AV_CODEC_PROP_LOSSLESS.

36 37 38 39 40 41 42 43 44 45 46
2012-08-18 - lavc 54.26 - avcodec.h
  Add codec descriptors for accessing codec properties without having
  to refer to a specific decoder or encoder.

  c223d79 - Add an AVCodecDescriptor struct and functions
            avcodec_descriptor_get() and avcodec_descriptor_next().
  51efed1 - Add AVCodecDescriptor.props and AV_CODEC_PROP_INTRA_ONLY.
  91e59fe - Add avcodec_descriptor_get_by_name().


2012-08-08 - 1d9c2dc - lavu 51.39 - avutil.h
47 48
  Don't implicitly include libavutil/common.h in avutil.h

  Add av_dict_count().

52
2012-08-07 - 104e10f - lavc 54.25 - avcodec.h
53
  Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
54 55 56 57
  To provide backwards compatibility, CodecID is now #defined as AVCodecID.
  Note that this can break user code that includes avcodec.h and uses the
  'CodecID' identifier. Such code should either #undef CodecID or stop using the
  CodecID name.

2012-05-09 - a5117a2 - lavc 54.13.1
117 118 119 120 121
  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).

  f1caf01 Allow doing av_write_frame(ctx, NULL) for flushing possible
          buffered data within a muxer. Added AVFMT_ALLOW_FLUSH for

  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.

  Add nb_samples and extended_data fields to AVFrame.
  Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
  Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
  avcodec_decode_audio4() writes output samples to an AVFrame, which allows
  audio decoders to use get_buffer().

  Move some AVCodecContext fields to a new private struct, AVCodecInternal,
  which is accessed from a new field, AVCodecContext.internal.
  - fields moved:
      AVCodecContext.internal_buffer       --> AVCodecInternal.buffer
      AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
      AVCodecContext.is_copy               --> AVCodecInternal.is_copy

  New interrupt callback API, allowing per-AVFormatContext/AVIOContext
  interrupt callbacks.
  6aa0b98 Add AVIOInterruptCB struct and the interrupt_callback field to
          AVFormatContext.
  1dee0ac Add avio_open2() with additional parameters. Those are
          an interrupt callback and an options AVDictionary.
          This will allow passing AVOptions to protocols after lavf
