  'PixelFormat' identifier. Such code should either #undef PixelFormat
  or stop using the PixelFormat name.

511

601 602 603 604 605
  For audio formats with fixed frame size, the last frame

1770
2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1771
  PKT_FLAG_KEY has been deprecated and will be dropped at the next

2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1775 1776 1777
  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
1778 1779 1780
  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.
1781

1782
2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()

1785
2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1786 1787 1788

  (lavf > 52.23.1, lavc > 52.10.0).

1789
2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1790 1791 1792 1793 1794
  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.

1795
2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1796 1797
  Introduce the av_fifo_space() function.

1798
2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket

  libavcodec/avcodec.h.

1802
2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1803 1804 1805 1806 1807
  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.
1808
  Re-sort the enum PixelFormat list accordingly.
1809 1810
  This change breaks API/ABI backward compatibility.

1811
2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1812 1813 1814 1815
  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.

1816
2009-03-21 - ee6624e - lavu 50.0.0  - av_random*
1817 1818 1819 1820
  The Mersenne Twister PRNG implemented through the av_random* functions
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  instead.

1821
2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer
1822 1823 1824 1825
  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
1826
  was changed to match av_fifo_generic_write.
1827 1828
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  applications, they may not use sizeof() or directly access members.
1829

1830
2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1831 1832
  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
