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

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

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

662 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
663 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().

665 audio decoders to use get_buffer().
667 2011-12-04 - 560f773 - lavc 53.24.0
668 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1282 Change the field types:
1283 enum PixelFormat format -> int format in AVFilterBuffer
1284 enum PixelFormat *formats -> int *formats in AVFilterFormats
1285 enum PixelFormat *format -> int format in AVFilterLink
1287 Change the function signatures:
1288 AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
1289 AVFilterFormats *avfilter_make_format_list(const int *fmts);
1291 int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
1292 int avfilter_add_format (AVFilterFormats **avff, int fmt);
1294 AVFilterFormats *avfilter_all_colorspaces(void); ->
1295 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
1297 This change breaks libavfilter API/ABI.

1486 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1487 Introduce the avfilter_next() function.
1489 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1490 Change the signature of avfilter_register() to make it return an
1491 int. This is required since now the registration operation may fail.
1493 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1494 Make the pixdesc.h API public.
1496 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1513 Add w and h fields to AVFilterPic.
1515 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1516 This is now an unsigned int instead of a signed int.
1518 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1519 Add a pts field to AVSubtitle which gives the subtitle packet pts
1520 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1521 not work right without this.
1523 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1524 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1525 major version. Use AV_PKT_FLAG_KEY instead.
1527 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1528 av_lockmgr_register() can be used to register a callback function
1529 that lavc (and in the future, libraries that depend on lavc) can use
1530 to implement mutexes. The application should provide a callback function
1531 that implements the AV_LOCK_* operations described in avcodec.h.
1532 When the lock manager is registered, FFmpeg is guaranteed to behave
1533 correctly in a multi-threaded application.
1535 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1536 av_free_packet() is no longer an inline function. It is now exported.
1538 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1539 Please use NULL instead. This has been supported since r16506
1540 (lavf > 52.23.1, lavc > 52.10.0).
1542 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1543 The old decoding functions are deprecated, all new code should use the
1544 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1545 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1546 argument instead of a const uint8_t *buf / int buf_size pair.
1548 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1549 Introduce the av_fifo_space() function.
1551 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1552 Move AVPacket declaration from libavformat/avformat.h to
1553 libavcodec/avcodec.h.
1555 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1556 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1557 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1558 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1559 PIX_FMT_BGR32_1 are now macros.
1560 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1561 Re-sort the enum PixelFormat list accordingly.
1562 This change breaks API/ABI backward compatibility.
1564 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1565 Add the enum PixelFormat values:
1566 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1567 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1569 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1570 The Mersenne Twister PRNG implemented through the av_random* functions
1571 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1574 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1575 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1576 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1577 and av_fifo_realloc2.
1578 In addition, the order of the function arguments of av_fifo_generic_read
1579 was changed to match av_fifo_generic_write.
1580 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1581 applications, they may not use sizeof() or directly access members.
1583 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1584 Introduce a new metadata API (see av_metadata_get() and friends).
1585 The old API is now deprecated and should not be used anymore. This especially
1586 includes the following structure fields:
1587 - AVFormatContext.title
1588 - AVFormatContext.author
1589 - AVFormatContext.copyright
1590 - AVFormatContext.comment
1591 - AVFormatContext.album
1592 - AVFormatContext.year
1593 - AVFormatContext.track
1594 - AVFormatContext.genre
1597 - AVProgram.provider_name
