1611 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1612 argument instead of a const uint8_t *buf / int buf_size pair.
1614 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1615 Introduce the av_fifo_space() function.
1617 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1618 Move AVPacket declaration from libavformat/avformat.h to
1619 libavcodec/avcodec.h.
1621 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1622 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1623 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1624 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1625 PIX_FMT_BGR32_1 are now macros.
1626 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1627 Re-sort the enum PixelFormat list accordingly.
1628 This change breaks API/ABI backward compatibility.
1630 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1631 Add the enum PixelFormat values:
1632 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1633 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1635 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1636 The Mersenne Twister PRNG implemented through the av_random* functions
1637 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1640 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1641 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1642 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1643 and av_fifo_realloc2.
1644 In addition, the order of the function arguments of av_fifo_generic_read
1645 was changed to match av_fifo_generic_write.
1646 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1647 applications, they may not use sizeof() or directly access members.
1649 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1650 Introduce a new metadata API (see av_metadata_get() and friends).
1651 The old API is now deprecated and should not be used anymore. This especially
1652 includes the following structure fields:
1653 - AVFormatContext.title
1654 - AVFormatContext.author
1655 - AVFormatContext.copyright
1656 - AVFormatContext.comment
1657 - AVFormatContext.album
1658 - AVFormatContext.year
1659 - AVFormatContext.track
1660 - AVFormatContext.genre
1663 - AVProgram.provider_name
