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

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

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

645 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
646 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().

648 audio decoders to use get_buffer().
650 2011-12-04 - 560f773 - lavc 53.24.0
651 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1473 Change the signature of avfilter_register() to make it return an
1474 int. This is required since now the registration operation may fail.
1476 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API

1501 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1502 Add a pts field to AVSubtitle which gives the subtitle packet pts
1503 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1504 not work right without this.
1506 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1507 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1508 major version. Use AV_PKT_FLAG_KEY instead.
1510 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1511 av_lockmgr_register() can be used to register a callback function
1512 that lavc (and in the future, libraries that depend on lavc) can use
1513 to implement mutexes. The application should provide a callback function
1514 that implements the AV_LOCK_* operations described in avcodec.h.
1515 When the lock manager is registered, FFmpeg is guaranteed to behave
1516 correctly in a multi-threaded application.
1518 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1519 av_free_packet() is no longer an inline function. It is now exported.
1521 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1522 Please use NULL instead. This has been supported since r16506
1523 (lavf > 52.23.1, lavc > 52.10.0).
1525 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1526 The old decoding functions are deprecated, all new code should use the
1527 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1528 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1529 argument instead of a const uint8_t *buf / int buf_size pair.
1531 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1532 Introduce the av_fifo_space() function.
1534 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1535 Move AVPacket declaration from libavformat/avformat.h to
1536 libavcodec/avcodec.h.
1538 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1539 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1540 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1541 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1542 PIX_FMT_BGR32_1 are now macros.
1543 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1544 Re-sort the enum PixelFormat list accordingly.
1545 This change breaks API/ABI backward compatibility.
1547 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1548 Add the enum PixelFormat values:
1549 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1550 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1552 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1553 The Mersenne Twister PRNG implemented through the av_random* functions
1554 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1557 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1558 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1559 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1560 and av_fifo_realloc2.
1561 In addition, the order of the function arguments of av_fifo_generic_read
1562 was changed to match av_fifo_generic_write.
1563 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1564 applications, they may not use sizeof() or directly access members.
1566 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1567 Introduce a new metadata API (see av_metadata_get() and friends).
1568 The old API is now deprecated and should not be used anymore. This especially
1569 includes the following structure fields:
1570 - AVFormatContext.title
1571 - AVFormatContext.author
1572 - AVFormatContext.copyright
1573 - AVFormatContext.comment
1574 - AVFormatContext.album
1575 - AVFormatContext.year
1576 - AVFormatContext.track
1577 - AVFormatContext.genre
1580 - AVProgram.provider_name
