[libav.git] / doc / APIchanges
1 Never assume the API of libav* to be stable unless at least 1 month has passed
2 since the last major version increase.

4 The last version increases were:
5 libavcodec: 2013-03-xx
6 libavdevice: 2013-03-xx
7 libavfilter: 2013-12-xx
8 libavformat: 2013-03-xx

14 API changes, most recent first:
15
16 2014-07-xx - xxxxxxx - lavc 55.56.0 - dv_profile.h
17 Add a public API for DV profile handling.
18
19 2014-06-xx - xxxxxxx - lavu 53.17.0 - imgutils.h
20 Add av_image_check_sar().
21
22 2014-06-xx - xxxxxxx - lavc 55.55.0 - avcodec.h
23 Add av_packet_rescale_ts() to simplify timestamp conversion.
24
25 2014-xx-xx - xxxxxxx - lavf 55.20.0 - avformat.h
26 The proper way for providing a hint about the desired timebase to the muxers
27 is now setting AVStream.time_base, instead of AVStream.codec.time_base as was
28 done previously. The old method is now deprecated.
29
30 2014-04-xx - xxxxxxx - lavc 55.54.0 - avcodec.h
31 Add AVCodecContext.side_data_only_packets to allow encoders to output packets
32 with only side data. This option may become mandatory in the future, so all
33 users are recommended to update their code and enable this option.
34
35 2014-xx-xx - xxxxxxx - lavu 53.16.0 - frame.h, pixfmt.h
36 Move all color-related enums (AVColorPrimaries, AVColorSpace, AVColorRange,
37 AVColorTransferCharacteristic, and AVChromaLocation) inside lavu.
38 Add AVFrame fields for them on the next lavu major bump.
39
40 2014-04-xx - xxxxxxx - lavr 1.3.0 - avresample.h
41 Add avresample_max_output_samples
42

48 Add av_stream_get_side_data() to access stream-level side data
49 in the same way as av_packet_get_side_data().

52 Add AV_FRAME_DATA_DISPLAYMATRIX for exporting frame-level
53 spatial rendering on video frames for proper display.

56 Add AV_PKT_DATA_DISPLAYMATRIX for exporting packet-level
57 spatial rendering on video frames for proper display.
58
59 2014-05-xx - xxxxxxx - lavf 55.17.1 - avformat.h
60 Deprecate AVStream.pts and the AVFrac struct, which was its only use case.
61 Those fields were poorly defined and not meant to be public, so there is

387 Libavresample is now stable.
388
389 2012-09-24 - a42aada - lavc 54.28.0 - avcodec.h
390 Add avcodec_free_frame(). This function must now
391 be used for freeing an AVFrame.
392
393 2012-09-12 - 8919fee - lavu 51.41.0 - audioconvert.h
394 Added AV_CH_LOW_FREQUENCY_2 channel mask value.

421 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
422 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
423 Note that this can break user code that includes avcodec.h and uses the
424 'CodecID' identifier. Such code should either #undef CodecID or stop using the
425 CodecID name.
426
427 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

484 2012-05-09 - a5117a2 - lavc 54.13.1
485 For audio formats with fixed frame size, the last frame
486 no longer needs to be padded with silence, libavcodec
487 will handle this internally (effectively all encoders
488 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
489

584
585 ------------------------------8<-------------------------------------

602
603 2011-12-25 - lavfi 2.14.0
604 e1d9dbf Add a new installed header - buffersrc.h

607 it allows for direct rendering.
608 1c9e340 Add avfilter_copy_frame_props() for copying properties from
609 AVFrame to AVFilterBufferRef.
610
611 2011-12-25 - lavc 53.31.0

629 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
630 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
631 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
632 audio decoders to use get_buffer().
633
634 2011-12-04 - 560f773 - lavc 53.24.0
635 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

1513 argument instead of a const uint8_t *buf / int buf_size pair.

1526 PIX_FMT_BGR32_1 are now macros.
1527 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1528 Re-sort the enum PixelFormat list accordingly.
1529 This change breaks API/ABI backward compatibility.

1531 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1532 Add the enum PixelFormat values:
1533 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1534 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1536 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1537 The Mersenne Twister PRNG implemented through the av_random* functions
1538 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1539 instead.

1541 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1542 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1543 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1544 and av_fifo_realloc2.
1545 In addition, the order of the function arguments of av_fifo_generic_read
1546 was changed to match av_fifo_generic_write.
1547 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1548 applications, they may not use sizeof() or directly access members.

1550 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API

1552 The old API is now deprecated and should not be used anymore. This especially
1553 includes the following structure fields:
1554 - AVFormatContext.title
1555 - AVFormatContext.author
1556 - AVFormatContext.copyright
1557 - AVFormatContext.comment
1558 - AVFormatContext.album
1559 - AVFormatContext.year
1560 - AVFormatContext.track
1561 - AVFormatContext.genre
1562 - AVStream.language
1563 - AVStream.filename
1564 - AVProgram.provider_name
1565 - AVProgram.name
1566 - AVChapter.title
