  776. argument instead of a const uint8_t *buf / int buf_size pair.
  777. 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

  783. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  784. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  785. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  786. PIX_FMT_BGR32_1 are now macros.
  787. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  788. Re-sort the enum PixelFormat list accordingly.
  789. This change breaks API/ABI backward compatibility.
  790. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  793. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  794. 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
  795. The Mersenne Twister PRNG implemented through the av_random* functions
  796. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  800. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  801. and av_fifo_realloc2.
  802. In addition, the order of the function arguments of av_fifo_generic_read
  803. was changed to match av_fifo_generic_write.
  804. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  805. applications, they may not use sizeof() or directly access members.
  806. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
  807. Introduce a new metadata API (see av_metadata_get() and friends).
  808. The old API is now deprecated and should not be used anymore. This especially
  809. includes the following structure fields:
