1 | Never assume the API of libav* to be stable unless at least 1 week has passed since |
2 | the last major version increase. | |
3 | The last version increases were: | |
4 | libavcodec: ? | |
5 | libavdevice: ? | |
6 | libavfilter: ? | |
7 | libavformat: ? | |
8 | libpostproc: ? | |
9 | libswscale: ? | |
10 | libavutil: 2009-03-08 | |

13 | API changes, most recent first: | |
14 | ||
04670366 SS |
15 | 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic |
16 | Added w and h fields to AVFilterPic. | |
17 | ||
b394438e RB |
18 | 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size |
19 | This is now an unsigned int instead of a signed int. | |
20 | ||
4bbe788a RD |
21 | 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts |
22 | Added a pts field to AVSubtitle which gives the subtitle's packet | |
23 | PTS in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will | |
24 | not work right without this. | |
25 | ||
8f3f2e06 RD |
26 | 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY |
27 | PKT_FLAG_KEY has been deprecated and will be dropped for the next | |
28 | major version. Use AV_PKT_FLAG_KEY instead. | |
29 | ||

30 | 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register() |
31 | av_lockmgr_register() can be used to register a callback function | |
32 | that lavc (and in the future, libraries that depend on lavc) can use | |
33 | to implement mutexes. The application should provide a callback function | |
34 | the implements the AV_LOCK_* operations described in avcodec.h. | |
35 | When the lock manager is registered FFmpeg is guaranteed to behave | |
36 | correct also in a multi-threaded application. | |

38 | 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet |
39 | av_free_packet() is no longer an inline function. It is now exported. | |
40 | ||
0c13bbf5 RD |
41 | 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree |
42 | Please use NULL instead. This has been supported since r16506 | |
43 | (lavf > 52.23.1, lavc > 52.10.0). | |
44 | ||
2851d225 RB |
45 | 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle |
46 | The old decoding functions are deprecated, all new code should use the | |
47 | new functions avcodec_decode_video2(), avcodec_decode_audio3() and | |
48 | avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt | |
49 | argument instead of a const uint8_t *buf / int buf_size pair. | |

51 | 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space |
52 | Introduce the av_fifo_space() function. | |
53 | ||
dd3bbb49 SS |
54 | 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket |
55 | Move AVPacket declaration from libavformat/avformat.h to | |
56 | libavcodec/avcodec.h. | |

58 | 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats |
59 | Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR, | |
60 | PIX_FMT_BGRA, which were defined as macros, defined as enum | |
61 | PixelFormat values, and viceversa make PIX_FMT_RGB32, | |
62 | PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros. | |
63 | Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32" | |
64 | aliases. | |
f3370e14 | 65 | Re-sort the enum PixelFormat list accordingly. |
5a43bbc3 SS |
66 | This change breaks API/ABI backward compatibility. |

dd3bbb49 SS |
68 | 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants |
69 | Add the enum PixelFormat values: | |
70 | PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE, | |
71 | PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE. | |

b4656e6b | 73 | 2009-03-21 - r18116 - lavu 50.0.0 - av_random* |
c8f742ca DB |
74 | The Mersenne Twister PRNG implemented through the av_random* functions |
75 | was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions | |
76 | instead. | |

78 | 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer |
79 | av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped | |
80 | and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write | |
81 | and av_fifo_realloc2. | |
82 | In addition, the order of the function arguments of av_fifo_generic_read | |
83 | were changed to match av_fifo_generic_write. | |
84 | The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by | |
85 | applications, they may not use sizeof() or directly access members. | |
22d4f236 | 86 | |
889cdae8 DB |
87 | 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API |
88 | Introduce a new metadata API (see av_metadata_get() and friends). | |
89 | The old API is now deprecated and should not be used anymore. This especially | |
429d6b21 | 90 | includes the following structure fields: |
