  1519.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  1520.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  1521.   argument instead of a const uint8_t *buf / int buf_size pair.

  1534.   PIX_FMT_BGR32_1 are now macros.

  1535.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  1536.   Re-sort the enum PixelFormat list accordingly.

  1537.   This change breaks API/ABI backward compatibility.

  1538. 

  1539. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  1540.   Add the enum PixelFormat values:

  1541.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  1542.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  1543. 

  1544. 2009-03-21 - ee6624e - lavu 50.0.0  - av_random*

  1545.   The Mersenne Twister PRNG implemented through the av_random* functions

  1546.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1547.   instead.

  1548. 

  1549. 2009-03-08 - 41dd680 - lavu 50.0.0  - AVFifoBuffer

  1550.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  1551.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  1552.   and av_fifo_realloc2.

  1553.   In addition, the order of the function arguments of av_fifo_generic_read

  1554.   was changed to match av_fifo_generic_write.

  1555.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  1556.   applications, they may not use sizeof() or directly access members.

  1557. 

  1558. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API

  1559.   Introduce a new metadata API (see av_metadata_get() and friends).

  1560.   The old API is now deprecated and should not be used anymore. This especially

  1561.   includes the following structure fields:

  1562.     - AVFormatContext.title

  1563.     - AVFormatContext.author

  1564.     - AVFormatContext.copyright

  1565.     - AVFormatContext.comment

  1566.     - AVFormatContext.album

  1567.     - AVFormatContext.year

  1568.     - AVFormatContext.track

  1569.     - AVFormatContext.genre

  1570.     - AVStream.language

  1571.     - AVStream.filename

  1572.     - AVProgram.provider_name

  1573.     - AVProgram.name

  1574.     - AVChapter.title
