2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
618
  The old decoding functions are deprecated, all new code should use the
619
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
620
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
621
  argument instead of a const uint8_t *buf / int buf_size pair.

2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
631 227d1b98 Diego Biurrun
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
632
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
633
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
634
  PIX_FMT_BGR32_1 are now macros.
635
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
636 f3370e14 Stefano Sabatini
  Re-sort the enum PixelFormat list accordingly.
637 5a43bbc3 Stefano Sabatini
  This change breaks API/ABI backward compatibility.

2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
640
  Add the enum PixelFormat values:
641
  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
642
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

2009-03-21 - r18116 - lavu 50.0.0  - av_random*
645 c8f742ca Diego Biurrun
  The Mersenne Twister PRNG implemented through the av_random* functions
646
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
647
  instead.

2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer
650
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
651
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
652
  and av_fifo_realloc2.
653
  In addition, the order of the function arguments of av_fifo_generic_read
654 227d1b98 Diego Biurrun
  was changed to match av_fifo_generic_write.
655 889cdae8 Diego Biurrun
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
656
  applications, they may not use sizeof() or directly access members.

2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
659
  Introduce a new metadata API (see av_metadata_get() and friends).
660
  The old API is now deprecated and should not be used anymore. This especially
661 429d6b21 Panagiotis Issaris
  includes the following structure fields:
