434 Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
435 To provide backwards compatibility, PixelFormat is now #defined as
437 Note that this can break user code that includes pixfmt.h and uses the
438 'PixelFormat' identifier. Such code should either #undef PixelFormat
439 or stop using the PixelFormat name.

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

1508 Remove the next field from AVFilter, this is not anymore required.
1510 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1511 Introduce the avfilter_next() function.
1513 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1514 Change the signature of avfilter_register() to make it return an
1515 int. This is required since now the registration operation may fail.
1517 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1518 Make the pixdesc.h API public.
1520 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1525 Add a description field to AVFilter.
1527 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()

1537 Add w and h fields to AVFilterPic.
1539 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1540 This is now an unsigned int instead of a signed int.
1542 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1543 Add a pts field to AVSubtitle which gives the subtitle packet pts
1544 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1545 not work right without this.
1547 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1548 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1549 major version. Use AV_PKT_FLAG_KEY instead.
1551 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1552 av_lockmgr_register() can be used to register a callback function
1553 that lavc (and in the future, libraries that depend on lavc) can use
1554 to implement mutexes. The application should provide a callback function
1555 that implements the AV_LOCK_* operations described in avcodec.h.
1556 When the lock manager is registered, FFmpeg is guaranteed to behave
1557 correctly in a multi-threaded application.
1559 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1560 av_free_packet() is no longer an inline function. It is now exported.
1562 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1563 Please use NULL instead. This has been supported since r16506
1564 (lavf > 52.23.1, lavc > 52.10.0).
1566 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1567 The old decoding functions are deprecated, all new code should use the
1568 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1569 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1570 argument instead of a const uint8_t *buf / int buf_size pair.
1572 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1573 Introduce the av_fifo_space() function.
1575 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1576 Move AVPacket declaration from libavformat/avformat.h to
1577 libavcodec/avcodec.h.
1579 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1580 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1581 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1582 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1583 PIX_FMT_BGR32_1 are now macros.
1584 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1585 Re-sort the enum PixelFormat list accordingly.
1586 This change breaks API/ABI backward compatibility.
1588 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1589 Add the enum PixelFormat values:
1590 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1591 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1593 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1594 The Mersenne Twister PRNG implemented through the av_random* functions
1595 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1598 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1599 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1600 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1601 and av_fifo_realloc2.
1602 In addition, the order of the function arguments of av_fifo_generic_read
1603 was changed to match av_fifo_generic_write.
1604 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1605 applications, they may not use sizeof() or directly access members.
1607 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1608 Introduce a new metadata API (see av_metadata_get() and friends).
1609 The old API is now deprecated and should not be used anymore. This especially
1610 includes the following structure fields:
1611 - AVFormatContext.title
1612 - AVFormatContext.author
1613 - AVFormatContext.copyright
1614 - AVFormatContext.comment
1615 - AVFormatContext.album
1616 - AVFormatContext.year
1617 - AVFormatContext.track
1618 - AVFormatContext.genre
1621 - AVProgram.provider_name
