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

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

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

649 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
650 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().

652 audio decoders to use get_buffer().
654 2011-12-04 - 560f773 - lavc 53.24.0
655 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1281 AVFilterFormats *avfilter_all_colorspaces(void); ->
1282 AVFilterFormats *avfilter_all_formats (enum AVMediaType type);
1284 This change breaks libavfilter API/ABI.

1476 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1477 Change the signature of avfilter_register() to make it return an
1478 int. This is required since now the registration operation may fail.
1480 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1481 Make the pixdesc.h API public.
1483 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1502 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1503 This is now an unsigned int instead of a signed int.
1505 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1506 Add a pts field to AVSubtitle which gives the subtitle packet pts
1507 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1508 not work right without this.
1510 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1511 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1512 major version. Use AV_PKT_FLAG_KEY instead.
1514 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1515 av_lockmgr_register() can be used to register a callback function
1516 that lavc (and in the future, libraries that depend on lavc) can use
1517 to implement mutexes. The application should provide a callback function
1518 that implements the AV_LOCK_* operations described in avcodec.h.
1519 When the lock manager is registered, FFmpeg is guaranteed to behave
1520 correctly in a multi-threaded application.
1522 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1523 av_free_packet() is no longer an inline function. It is now exported.
1525 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1526 Please use NULL instead. This has been supported since r16506
1527 (lavf > 52.23.1, lavc > 52.10.0).
1529 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1530 The old decoding functions are deprecated, all new code should use the
1531 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1532 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1533 argument instead of a const uint8_t *buf / int buf_size pair.
1535 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1536 Introduce the av_fifo_space() function.
1538 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1539 Move AVPacket declaration from libavformat/avformat.h to
1540 libavcodec/avcodec.h.
1542 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1543 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1544 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1545 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1546 PIX_FMT_BGR32_1 are now macros.
1547 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1548 Re-sort the enum PixelFormat list accordingly.
1549 This change breaks API/ABI backward compatibility.
1551 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1552 Add the enum PixelFormat values:
1553 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1554 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1556 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1557 The Mersenne Twister PRNG implemented through the av_random* functions
1558 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1561 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1562 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1563 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1564 and av_fifo_realloc2.
1565 In addition, the order of the function arguments of av_fifo_generic_read
1566 was changed to match av_fifo_generic_write.
1567 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1568 applications, they may not use sizeof() or directly access members.
1570 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1571 Introduce a new metadata API (see av_metadata_get() and friends).
1572 The old API is now deprecated and should not be used anymore. This especially
1573 includes the following structure fields:
1574 - AVFormatContext.title
1575 - AVFormatContext.author
1576 - AVFormatContext.copyright
1577 - AVFormatContext.comment
1578 - AVFormatContext.album
1579 - AVFormatContext.year
1580 - AVFormatContext.track
1581 - AVFormatContext.genre
1584 - AVProgram.provider_name
