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

435 'PixelFormat' identifier. Such code should either #undef PixelFormat
436 or stop using the PixelFormat name.

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

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

1505 Remove the next field from AVFilter, this is not anymore required.
1507 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1508 Introduce the avfilter_next() function.
1510 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1511 Change the signature of avfilter_register() to make it return an
1512 int. This is required since now the registration operation may fail.
1514 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1515 Make the pixdesc.h API public.
1517 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1518 Add a next field to AVFilter, this is used for simplifying the

1522 Add a description field to AVFilter.
1524 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()

1534 Add w and h fields to AVFilterPic.
1536 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1537 This is now an unsigned int instead of a signed int.
1539 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1540 Add a pts field to AVSubtitle which gives the subtitle packet pts
1541 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1542 not work right without this.
1544 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1545 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1546 major version. Use AV_PKT_FLAG_KEY instead.
1548 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1549 av_lockmgr_register() can be used to register a callback function
1550 that lavc (and in the future, libraries that depend on lavc) can use
1551 to implement mutexes. The application should provide a callback function
1552 that implements the AV_LOCK_* operations described in avcodec.h.
1553 When the lock manager is registered, FFmpeg is guaranteed to behave
1554 correctly in a multi-threaded application.
1556 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1557 av_free_packet() is no longer an inline function. It is now exported.
1559 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1560 Please use NULL instead. This has been supported since r16506
1561 (lavf > 52.23.1, lavc > 52.10.0).
1563 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1564 The old decoding functions are deprecated, all new code should use the
1565 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1566 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1567 argument instead of a const uint8_t *buf / int buf_size pair.
1569 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1570 Introduce the av_fifo_space() function.
1572 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1573 Move AVPacket declaration from libavformat/avformat.h to
1574 libavcodec/avcodec.h.
1576 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1577 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1578 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1579 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1580 PIX_FMT_BGR32_1 are now macros.
1581 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1582 Re-sort the enum PixelFormat list accordingly.
1583 This change breaks API/ABI backward compatibility.
1585 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1586 Add the enum PixelFormat values:
1587 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1588 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1590 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1591 The Mersenne Twister PRNG implemented through the av_random* functions
1592 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1595 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1596 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1597 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1598 and av_fifo_realloc2.
1599 In addition, the order of the function arguments of av_fifo_generic_read
1600 was changed to match av_fifo_generic_write.
1601 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1602 applications, they may not use sizeof() or directly access members.
1604 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1605 Introduce a new metadata API (see av_metadata_get() and friends).
1606 The old API is now deprecated and should not be used anymore. This especially
1607 includes the following structure fields:
1608 - AVFormatContext.title
1609 - AVFormatContext.author
1610 - AVFormatContext.copyright
1611 - AVFormatContext.comment
1612 - AVFormatContext.album
1613 - AVFormatContext.year
1614 - AVFormatContext.track
1615 - AVFormatContext.genre
1618 - AVProgram.provider_name
