1617 that implements the AV_LOCK_* operations described in avcodec.h.
1618 When the lock manager is registered, FFmpeg is guaranteed to behave
1619 correctly in a multi-threaded application.
1621 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1622 av_free_packet() is no longer an inline function. It is now exported.
1624 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1625 Please use NULL instead. This has been supported since r16506
1626 (lavf > 52.23.1, lavc > 52.10.0).
1628 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1629 The old decoding functions are deprecated, all new code should use the
1630 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1631 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1632 argument instead of a const uint8_t *buf / int buf_size pair.
1634 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1635 Introduce the av_fifo_space() function.
1637 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1638 Move AVPacket declaration from libavformat/avformat.h to
1639 libavcodec/avcodec.h.
1641 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1642 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1643 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1644 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1645 PIX_FMT_BGR32_1 are now macros.
1646 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1647 Re-sort the enum PixelFormat list accordingly.
1648 This change breaks API/ABI backward compatibility.
1650 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1651 Add the enum PixelFormat values:
1652 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1653 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1655 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1656 The Mersenne Twister PRNG implemented through the av_random* functions
1657 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1660 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1661 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1662 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1663 and av_fifo_realloc2.
1664 In addition, the order of the function arguments of av_fifo_generic_read
1665 was changed to match av_fifo_generic_write.
1666 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1667 applications, they may not use sizeof() or directly access members.
1669 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1670 Introduce a new metadata API (see av_metadata_get() and friends).
1671 The old API is now deprecated and should not be used anymore. This especially
1672 includes the following structure fields:
1673 - AVFormatContext.title
1674 - AVFormatContext.author
1675 - AVFormatContext.copyright
1676 - AVFormatContext.comment
1677 - AVFormatContext.album
1678 - AVFormatContext.year
1679 - AVFormatContext.track
1680 - AVFormatContext.genre
1683 - AVProgram.provider_name
