lavc: fix mixing CODEC_ID/AV_CODEC_ID in C++ code.
[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.
3
4 The last version increases were:
5 libavcodec: 2012-01-27
6 libavdevice: 2011-04-18
7 libavfilter: 2012-06-22
8 libavformat: 2012-01-27
9 libavresample: 2012-04-24
10 libswscale: 2011-06-20
11 libavutil: 2011-04-18

14 API changes, most recent first:
15
16 2012-08-08 - xxxxxxx - lavu 51.38 - dict.h
17 Add av_dict_count().
18
19 2012-08-xx - xxxxxxx - lavc 54.25 - avcodec.h
20 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
21 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
22 Note that this can break user code that includes avcodec.h and uses the
23 'CodecID' identifier. Such code should either #undef CodecID or stop using the
24 CodecID name.
25
26 2012-08-03 - xxxxxxx - lavu 51.37.1 - cpu.h
27 lsws 2.1.1 - swscale.h
28 Rename AV_CPU_FLAG_MMX2 ---> AV_CPU_FLAG_MMXEXT.
29 Rename SWS_CPU_CAPS_MMX2 ---> SWS_CPU_CAPS_MMXEXT.
30
31 2012-07-xx - xxxxxxx - lavf 54.13.0 - avformat.h
32 Add AVFMT_FLAG_NOBUFFER for low latency use cases.
33
34 2012-07-xx - xxxxxxx - lavfi 3.0.0 - avfilter.h
35 Add avfilter_unref_bufferp().
36
37 2012-07-10 - 5fade8a - lavu 51.37.0
38 Add av_malloc_array() and av_mallocz_array()
39

42
43 2012-06-20 - ae0a301 - lavu 51.33.0
44 Move av_gettime() to libavutil, add libavutil/time.h
45

48
49 2012-06-12 - 9baeff9 - lavfi 2.23.0 - avfilter.h
50 Add AVFilterContext.nb_inputs/outputs. Deprecate
51 AVFilterContext.input/output_count.
52
53 2012-06-12 - 84b9fbe - lavfi 2.22.0 - avfilter.h
54 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
55 should now be used instead of accessing AVFilterPad members
56 directly.
57
58 2012-06-12 - b0f0dfc - lavu 51.32.0 - audioconvert.h
59 Add av_get_channel_layout_channel_index(), av_get_channel_name()

67 non-increasing monotone timestamps.
68
69 2012-05-15 - lavfi 2.17.0
70 Add support for audio filters
71 ac71230/a2cd9be - add video/audio buffer sink in a new installed
72 header buffersink.h
73 720c6b7 - add av_buffersrc_write_frame(), deprecate

82
83 2012-05-09 - a5117a2 - lavc 54.13.1
84 For audio formats with fixed frame size, the last frame
85 no longer needs to be padded with silence, libavcodec
86 will handle this internally (effectively all encoders
87 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).
88

179
180 ------------------------------8<-------------------------------------
181 0.8 branch was cut here
182 ----------------------------->8--------------------------------------

201 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
202 it allows for direct rendering.
203 1c9e340 Add avfilter_copy_frame_props() for copying properties from
204 AVFrame to AVFilterBufferRef.
205
206 2011-12-25 - lavc 53.31.0

224 audio decoders to use get_buffer().
225
226 2011-12-04 - 560f773 - lavc 53.24.0
227 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

242 - fields moved:
243 AVCodecContext.internal_buffer --> AVCodecInternal.buffer
244 AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
245 AVCodecContext.is_copy --> AVCodecInternal.is_copy
246
247 2011-11-16 - 6270671 - lavu 51.16.0

1043
1044 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1045 Change the signature of avfilter_register() to make it return an

1049 Make the pixdesc.h API public.

1072
1073 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1074 Add a pts field to AVSubtitle which gives the subtitle packet pts
1075 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1076 not work right without this.
1077
1078 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1079 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1081
1082 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1083 av_lockmgr_register() can be used to register a callback function
1084 that lavc (and in the future, libraries that depend on lavc) can use
1085 to implement mutexes. The application should provide a callback function
1086 that implements the AV_LOCK_* operations described in avcodec.h.
1087 When the lock manager is registered, FFmpeg is guaranteed to behave
1088 correctly in a multi-threaded application.
1089
1090 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1091 av_free_packet() is no longer an inline function. It is now exported.
1092
1093 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1094 Please use NULL instead. This has been supported since r16506
1095 (lavf > 52.23.1, lavc > 52.10.0).
1096
1097 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1098 The old decoding functions are deprecated, all new code should use the
1099 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1100 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1101 argument instead of a const uint8_t *buf / int buf_size pair.
1102
1103 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1108 libavcodec/avcodec.h.
1109
1110 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1111 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1112 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1113 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1114 PIX_FMT_BGR32_1 are now macros.
1115 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1116 Re-sort the enum PixelFormat list accordingly.
1117 This change breaks API/ABI backward compatibility.
1118
1119 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1120 Add the enum PixelFormat values:
1121 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1122 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1123
1124 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1125 The Mersenne Twister PRNG implemented through the av_random* functions
1126 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1127 instead.
1128
1129 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1130 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1131 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1132 and av_fifo_realloc2.
1133 In addition, the order of the function arguments of av_fifo_generic_read
1134 was changed to match av_fifo_generic_write.
1135 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1136 applications, they may not use sizeof() or directly access members.
1137
1138 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1139 Introduce a new metadata API (see av_metadata_get() and friends).
1140 The old API is now deprecated and should not be used anymore. This especially
1141 includes the following structure fields:
1142 - AVFormatContext.title
1143 - AVFormatContext.author
1144 - AVFormatContext.copyright
1145 - AVFormatContext.comment
1146 - AVFormatContext.album
1147 - AVFormatContext.year
1148 - AVFormatContext.track
1149 - AVFormatContext.genre
1150 - AVStream.language
1151 - AVStream.filename
1152 - AVProgram.provider_name
1153 - AVProgram.name
1154 - AVChapter.title
