428 To provide backwards compatibility, PixelFormat is now #defined as
430 Note that this can break user code that includes pixfmt.h and uses the
431 'PixelFormat' identifier. Such code should either #undef PixelFormat
432 or stop using the PixelFormat name.

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

654 e1d9dbf Add a new installed header - buffersrc.h
655 It contains a new function av_buffersrc_buffer() that allows passing
656 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()

1501 Remove the next field from AVFilter, this is not anymore required.
1503 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1504 Introduce the avfilter_next() function.
1506 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1507 Change the signature of avfilter_register() to make it return an
1508 int. This is required since now the registration operation may fail.
1510 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1511 Make the pixdesc.h API public.
1513 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1514 Add a next field to AVFilter, this is used for simplifying the

1518 Add a description field to AVFilter.
1520 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1521 Change the interface of avfilter_make_format_list() from

1530 Add w and h fields to AVFilterPic.
1532 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1533 This is now an unsigned int instead of a signed int.
1535 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1536 Add a pts field to AVSubtitle which gives the subtitle packet pts
1537 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1538 not work right without this.
1540 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1541 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1542 major version. Use AV_PKT_FLAG_KEY instead.
1544 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1545 av_lockmgr_register() can be used to register a callback function
1546 that lavc (and in the future, libraries that depend on lavc) can use
1547 to implement mutexes. The application should provide a callback function
1548 that implements the AV_LOCK_* operations described in avcodec.h.
1549 When the lock manager is registered, FFmpeg is guaranteed to behave
1550 correctly in a multi-threaded application.
1552 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1553 av_free_packet() is no longer an inline function. It is now exported.
1555 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1556 Please use NULL instead. This has been supported since r16506
1557 (lavf > 52.23.1, lavc > 52.10.0).
1559 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1560 The old decoding functions are deprecated, all new code should use the
1561 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1562 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1563 argument instead of a const uint8_t *buf / int buf_size pair.
1565 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1566 Introduce the av_fifo_space() function.
1568 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1569 Move AVPacket declaration from libavformat/avformat.h to
1570 libavcodec/avcodec.h.
1572 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1573 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1574 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1575 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1576 PIX_FMT_BGR32_1 are now macros.
1577 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1578 Re-sort the enum PixelFormat list accordingly.
1579 This change breaks API/ABI backward compatibility.
1581 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1582 Add the enum PixelFormat values:
1583 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1584 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1586 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1587 The Mersenne Twister PRNG implemented through the av_random* functions
1588 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1591 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1592 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1593 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1594 and av_fifo_realloc2.
1595 In addition, the order of the function arguments of av_fifo_generic_read
1596 was changed to match av_fifo_generic_write.
1597 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1598 applications, they may not use sizeof() or directly access members.
1600 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1601 Introduce a new metadata API (see av_metadata_get() and friends).
1602 The old API is now deprecated and should not be used anymore. This especially
1603 includes the following structure fields:
1604 - AVFormatContext.title
1605 - AVFormatContext.author
1606 - AVFormatContext.copyright
1607 - AVFormatContext.comment
1608 - AVFormatContext.album
1609 - AVFormatContext.year
1610 - AVFormatContext.track
1611 - AVFormatContext.genre
1614 - AVProgram.provider_name
