451 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
452 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
453 Note that this can break user code that includes avcodec.h and uses the
454 'CodecID' identifier. Such code should either #undef CodecID or stop using the

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

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

1277 Add a type field to AVFilterLink.
1279 Change the field types:
1280 enum PixelFormat format -> int format in AVFilterBuffer
1281 enum PixelFormat *formats -> int *formats in AVFilterFormats
1282 enum PixelFormat *format -> int format in AVFilterLink
1284 Change the function signatures:
1285 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
1286 AVFilterFormats *avfilter_make_format_list(const int *fmts);
1288 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
1289 int avfilter_add_format (AVFilterFormats **avff, int fmt);
1291 AVFilterFormats *avfilter_all_colorspaces(void); ->
1292 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
1294 This change breaks libavfilter API/ABI.

1483 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1484 Introduce the avfilter_next() function.
1486 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1487 Change the signature of avfilter_register() to make it return an
1488 int. This is required since now the registration operation may fail.
1490 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1491 Make the pixdesc.h API public.
1493 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1494 Add a next field to AVFilter, this is used for simplifying the

1498 Add a description field to AVFilter.
1500 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1501 Change the interface of avfilter_make_format_list() from

1510 Add w and h fields to AVFilterPic.
1512 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1513 This is now an unsigned int instead of a signed int.
1515 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1516 Add a pts field to AVSubtitle which gives the subtitle packet pts
1517 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1518 not work right without this.
1520 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1521 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1522 major version. Use AV_PKT_FLAG_KEY instead.
1524 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1525 av_lockmgr_register() can be used to register a callback function
1526 that lavc (and in the future, libraries that depend on lavc) can use
1527 to implement mutexes. The application should provide a callback function
1528 that implements the AV_LOCK_* operations described in avcodec.h.
1529 When the lock manager is registered, FFmpeg is guaranteed to behave
1530 correctly in a multi-threaded application.
1532 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1533 av_free_packet() is no longer an inline function. It is now exported.
1535 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1536 Please use NULL instead. This has been supported since r16506
1537 (lavf > 52.23.1, lavc > 52.10.0).
1539 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1540 The old decoding functions are deprecated, all new code should use the
1541 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1542 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1543 argument instead of a const uint8_t *buf / int buf_size pair.
1545 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1546 Introduce the av_fifo_space() function.
1548 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1549 Move AVPacket declaration from libavformat/avformat.h to
1550 libavcodec/avcodec.h.
1552 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1553 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1554 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1555 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1556 PIX_FMT_BGR32_1 are now macros.
1557 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1558 Re-sort the enum PixelFormat list accordingly.
1559 This change breaks API/ABI backward compatibility.
1561 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1562 Add the enum PixelFormat values:
1563 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1564 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1566 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1567 The Mersenne Twister PRNG implemented through the av_random* functions
1568 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1571 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1572 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1573 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1574 and av_fifo_realloc2.
1575 In addition, the order of the function arguments of av_fifo_generic_read
1576 was changed to match av_fifo_generic_write.
1577 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1578 applications, they may not use sizeof() or directly access members.
1580 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1581 Introduce a new metadata API (see av_metadata_get() and friends).
1582 The old API is now deprecated and should not be used anymore. This especially
1583 includes the following structure fields:
1584 - AVFormatContext.title
1585 - AVFormatContext.author
1586 - AVFormatContext.copyright
1587 - AVFormatContext.comment
1588 - AVFormatContext.album
1589 - AVFormatContext.year
1590 - AVFormatContext.track
1591 - AVFormatContext.genre
1594 - AVProgram.provider_name
