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

1300 Change the function signatures:
1301 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
1302 AVFilterFormats *avfilter_make_format_list(const int *fmts);
1304 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
1305 int avfilter_add_format (AVFilterFormats **avff, int fmt);
1307 AVFilterFormats *avfilter_all_colorspaces(void); ->

1499 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1500 Introduce the avfilter_next() function.
1502 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1503 Change the signature of avfilter_register() to make it return an
1504 int. This is required since now the registration operation may fail.
1506 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1507 Make the pixdesc.h API public.
1509 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1526 Add w and h fields to AVFilterPic.
1528 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1529 This is now an unsigned int instead of a signed int.
1531 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1532 Add a pts field to AVSubtitle which gives the subtitle packet pts
1533 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1534 not work right without this.
1536 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1537 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1538 major version. Use AV_PKT_FLAG_KEY instead.
1540 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1541 av_lockmgr_register() can be used to register a callback function
1542 that lavc (and in the future, libraries that depend on lavc) can use
1543 to implement mutexes. The application should provide a callback function
1544 that implements the AV_LOCK_* operations described in avcodec.h.
1545 When the lock manager is registered, FFmpeg is guaranteed to behave
1546 correctly in a multi-threaded application.
1548 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1549 av_free_packet() is no longer an inline function. It is now exported.
1551 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1552 Please use NULL instead. This has been supported since r16506
1553 (lavf > 52.23.1, lavc > 52.10.0).
1555 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1556 The old decoding functions are deprecated, all new code should use the
1557 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1558 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1559 argument instead of a const uint8_t *buf / int buf_size pair.
1561 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1562 Introduce the av_fifo_space() function.
1564 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1565 Move AVPacket declaration from libavformat/avformat.h to
1566 libavcodec/avcodec.h.
1568 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1569 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1570 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1571 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1572 PIX_FMT_BGR32_1 are now macros.
1573 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1574 Re-sort the enum PixelFormat list accordingly.
1575 This change breaks API/ABI backward compatibility.
1577 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1578 Add the enum PixelFormat values:
1579 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1580 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1582 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1583 The Mersenne Twister PRNG implemented through the av_random* functions
1584 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1587 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1588 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1589 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1590 and av_fifo_realloc2.
1591 In addition, the order of the function arguments of av_fifo_generic_read
1592 was changed to match av_fifo_generic_write.
1593 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1594 applications, they may not use sizeof() or directly access members.
1596 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1597 Introduce a new metadata API (see av_metadata_get() and friends).
1598 The old API is now deprecated and should not be used anymore. This especially
1599 includes the following structure fields:
1600 - AVFormatContext.title
1601 - AVFormatContext.author
1602 - AVFormatContext.copyright
1603 - AVFormatContext.comment
1604 - AVFormatContext.album
1605 - AVFormatContext.year
1606 - AVFormatContext.track
1607 - AVFormatContext.genre
1610 - AVProgram.provider_name
