  1571.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  1572.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  1573.   argument instead of a const uint8_t *buf / int buf_size pair.

  1586.   PIX_FMT_BGR32_1 are now macros.

  1587.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1588.   Re-sort the enum PixelFormat list accordingly.

  1589.   This change breaks API/ABI backward compatibility.

  1590. 

  1591. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1592.   Add the enum PixelFormat values:

  1593.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1594.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1597.   The Mersenne Twister PRNG implemented through the av_random* functions

  1598.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1599.   instead.

  1601. 2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer

  1602.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1603.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1604.   and av_fifo_realloc2.

  1605.   In addition, the order of the function arguments of av_fifo_generic_read

  1606.   was changed to match av_fifo_generic_write.

  1607.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1608.   applications, they may not use sizeof() or directly access members.
