2011-12-25 - lavfi 2.14.0
  e1d9dbf Add a new installed header - buffersrc.h

  AVFrame to AVFilterBufferRef.

209 210 211 212 213

      AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
      AVCodecContext.is_copy               --> AVCodecInternal.is_copy

2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1086 1087
  Introduce the av_fifo_space() function.

1088
2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1089 1090 1091
  Move AVPacket declaration from libavformat/avformat.h to
  libavcodec/avcodec.h.

2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1093 1094 1095 1096 1097
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  PIX_FMT_BGR32_1 are now macros.
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1098
  Re-sort the enum PixelFormat list accordingly.
1099 1100
  This change breaks API/ABI backward compatibility.

1101
2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1102 1103 1104 1105
  Add the enum PixelFormat values:
  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1106
2009-03-21 - ee6624e - lavu 50.0.0  - av_random*
1107 1108 1109 1110
  The Mersenne Twister PRNG implemented through the av_random* functions
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  instead.

1111
2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer
1112 1113 1114 1115
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  and av_fifo_realloc2.
  In addition, the order of the function arguments of av_fifo_generic_read
1116
  was changed to match av_fifo_generic_write.
1117 1118
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  applications, they may not use sizeof() or directly access members.

2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1121 1122
  Introduce a new metadata API (see av_metadata_get() and friends).
  The old API is now deprecated and should not be used anymore. This especially
