  For audio formats with fixed frame size, the last frame

2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1660 1661
  This is now an unsigned int instead of a signed int.

1662
2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1663 1664
  Add a pts field to AVSubtitle which gives the subtitle packet pts
  in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1665 1666
  not work right without this.

1667
2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1668
  PKT_FLAG_KEY has been deprecated and will be dropped at the next
1669 1670
  major version. Use AV_PKT_FLAG_KEY instead.

1671
2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1672 1673 1674
  av_lockmgr_register() can be used to register a callback function
  that lavc (and in the future, libraries that depend on lavc) can use
  to implement mutexes. The application should provide a callback function
1675 1676 1677
  that implements the AV_LOCK_* operations described in avcodec.h.
  When the lock manager is registered, FFmpeg is guaranteed to behave
  correctly in a multi-threaded application.

2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1680 1681
  av_free_packet() is no longer an inline function. It is now exported.

1682
2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1683 1684 1685
  Please use NULL instead. This has been supported since r16506
  (lavf > 52.23.1, lavc > 52.10.0).

1686
2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1687 1688 1689 1690 1691
  The old decoding functions are deprecated, all new code should use the
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  argument instead of a const uint8_t *buf / int buf_size pair.

1692
2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1693 1694
  Introduce the av_fifo_space() function.

1695
2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1696 1697 1698
  Move AVPacket declaration from libavformat/avformat.h to
  libavcodec/avcodec.h.

1699
2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1700 1701 1702 1703 1704
  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.
1705
  Re-sort the enum PixelFormat list accordingly.
1706 1707
  This change breaks API/ABI backward compatibility.

1708
2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1709 1710 1711 1712
  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.

1713
2009-03-21 - ee6624e - lavu 50.0.0  - av_random*
1714 1715 1716 1717
  The Mersenne Twister PRNG implemented through the av_random* functions
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  instead.

1718
2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer
1719 1720 1721 1722
  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
1723
  was changed to match av_fifo_generic_write.
1724 1725
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  applications, they may not use sizeof() or directly access members.
1726

1727
2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1728 1729
  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
