441 To provide backwards compatibility, PixelFormat is now #defined as

444 'PixelFormat' identifier. Such code should either #undef PixelFormat
445 or stop using the PixelFormat name.

548 For audio formats with fixed frame size, the last frame
549 no longer needs to be padded with silence, libavcodec
550 will handle this internally (effectively all encoders
551 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

1514 Remove the next field from AVFilter, this is not anymore required.
1516 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1517 Introduce the avfilter_next() function.
1519 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1520 Change the signature of avfilter_register() to make it return an
1521 int. This is required since now the registration operation may fail.
1523 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1524 Make the pixdesc.h API public.
1526 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1543 Add w and h fields to AVFilterPic.
1545 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1546 This is now an unsigned int instead of a signed int.
1548 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1549 Add a pts field to AVSubtitle which gives the subtitle packet pts
1550 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1551 not work right without this.
1553 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1554 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1555 major version. Use AV_PKT_FLAG_KEY instead.
1557 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1558 av_lockmgr_register() can be used to register a callback function
1559 that lavc (and in the future, libraries that depend on lavc) can use
1560 to implement mutexes. The application should provide a callback function
1561 that implements the AV_LOCK_* operations described in avcodec.h.
1562 When the lock manager is registered, FFmpeg is guaranteed to behave
1563 correctly in a multi-threaded application.
1565 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1566 av_free_packet() is no longer an inline function. It is now exported.
1568 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1569 Please use NULL instead. This has been supported since r16506
1570 (lavf > 52.23.1, lavc > 52.10.0).
1572 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1573 The old decoding functions are deprecated, all new code should use the
1574 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1575 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1576 argument instead of a const uint8_t *buf / int buf_size pair.
1578 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1579 Introduce the av_fifo_space() function.
1581 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1582 Move AVPacket declaration from libavformat/avformat.h to
1583 libavcodec/avcodec.h.
1585 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1586 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1587 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1588 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1589 PIX_FMT_BGR32_1 are now macros.
1590 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1591 Re-sort the enum PixelFormat list accordingly.
1592 This change breaks API/ABI backward compatibility.
1594 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1595 Add the enum PixelFormat values:
1596 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1597 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1599 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1600 The Mersenne Twister PRNG implemented through the av_random* functions
1601 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1604 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1605 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1606 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1607 and av_fifo_realloc2.
1608 In addition, the order of the function arguments of av_fifo_generic_read
1609 was changed to match av_fifo_generic_write.
1610 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1611 applications, they may not use sizeof() or directly access members.
1613 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1614 Introduce a new metadata API (see av_metadata_get() and friends).
1615 The old API is now deprecated and should not be used anymore. This especially
1616 includes the following structure fields:
1617 - AVFormatContext.title
1618 - AVFormatContext.author
1619 - AVFormatContext.copyright
1620 - AVFormatContext.comment
1621 - AVFormatContext.album
1622 - AVFormatContext.year
1623 - AVFormatContext.track
1624 - AVFormatContext.genre
1627 - AVProgram.provider_name
