2 since the last major version increase.

14 API changes, most recent first:
15
16 2012-xx-xx - xxxxxxx - lavu 52.1.0 - intmath.h
17 Add av_ctz() for trailing zero bit count
18
19 2012-10-18 - xxxxxxx - lavu 51.45.0 - error.h
20 Add AVERROR_EXPERIMENTAL
21
22 2012-10-12 - xxxxxxx - lavu 51.44.0 - pixdesc.h
23 Add functions for accessing pixel format descriptors.
24 Accessing the av_pix_fmt_descriptors array directly is now
25 deprecated.
26
27 2012-10-xx - xxxxxxx - lavu 51.43.0 - aes.h, md5.h, sha.h, tree.h
28 Add functions for allocating the opaque contexts for the algorithms,
29 deprecate the context size variables.
30
31 2012-10-xx - xxxxxxx - lavf 54.18.0 - avio.h
32 Add avio_closep to complement avio_close.
33
34 2012-10-xx - xxxxxxx - lavu 51.42.0 - pixfmt.h
35 Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
36 To provide backwards compatibility, PixelFormat is now #defined as
37 AVPixelFormat.
38 Note that this can break user code that includes pixfmt.h and uses the
39 'PixelFormat' identifier. Such code should either #undef PixelFormat
40 or stop using the PixelFormat name.
41
42 2012-10-05 - e7ba5b1 - lavr 1.0.0 - avresample.h
43 Data planes parameters to avresample_convert() and
44 avresample_read() are now uint8_t** instead of void**.
45 Libavresample is now stable.
46
47 2012-09-24 - a42aada - lavc 54.28.0 - avcodec.h
48 Add avcodec_free_frame(). This function must now
49 be used for freeing an AVFrame.
50
51 2012-09-12 - 8919fee - lavu 51.41.0 - audioconvert.h
52 Added AV_CH_LOW_FREQUENCY_2 channel mask value.
53
54 2012-09-04 - 686a329 - lavu 51.40.0 - opt.h
55 Reordered the fields in default_val in AVOption, changed which
56 default_val field is used for which AVOptionType.
57
58 2012-08-30 - a231832 - lavc 54.26.1 - avcodec.h
59 Add codec descriptor properties AV_CODEC_PROP_LOSSY and
60 AV_CODEC_PROP_LOSSLESS.
61
62 2012-08-18 - lavc 54.26 - avcodec.h
63 Add codec descriptors for accessing codec properties without having
64 to refer to a specific decoder or encoder.
65
66 c223d79 - Add an AVCodecDescriptor struct and functions
67 avcodec_descriptor_get() and avcodec_descriptor_next().
68 51efed1 - Add AVCodecDescriptor.props and AV_CODEC_PROP_INTRA_ONLY.
69 91e59fe - Add avcodec_descriptor_get_by_name().
70

76 Add av_dict_count().
77
78 2012-08-07 - 104e10f - lavc 54.25 - avcodec.h
79 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
80 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
81 Note that this can break user code that includes avcodec.h and uses the
82 'CodecID' identifier. Such code should either #undef CodecID or stop using the
83 CodecID name.
84
85 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h
86 lsws 2.1.1 - swscale.h

110 AVFilterContext.input/output_count.
111
112 2012-06-12 - 84b9fbe - lavfi 2.22.0 - avfilter.h
113 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those

142 2012-05-09 - a5117a2 - lavc 54.13.1
143 For audio formats with fixed frame size, the last frame
144 no longer needs to be padded with silence, libavcodec
145 will handle this internally (effectively all encoders
146 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

258 e1d9dbf Add a new installed header - buffersrc.h
259 It contains a new function av_buffersrc_buffer() that allows passing
260 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
261 it allows for direct rendering.
262 1c9e340 Add avfilter_copy_frame_props() for copying properties from
263 AVFrame to AVFilterBufferRef.
264
265 2011-12-25 - lavc 53.31.0

282 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
283 audio decoders to use get_buffer().
284
285 2011-12-04 - 560f773 - lavc 53.24.0
286 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

300 which is accessed from a new field, AVCodecContext.internal.
301 - fields moved:
302 AVCodecContext.internal_buffer --> AVCodecInternal.buffer
303 AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
304 AVCodecContext.is_copy --> AVCodecInternal.is_copy
305
306 2011-11-16 - 6270671 - lavu 51.16.0
307 Add av_timegm()
308
309 2011-11-13 - lavf 53.15.0

1170 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1171 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1172 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1173 PIX_FMT_BGR32_1 are now macros.
1174 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1175 Re-sort the enum PixelFormat list accordingly.
1176 This change breaks API/ABI backward compatibility.

1178 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1179 Add the enum PixelFormat values:
1180 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1181 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1183 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1184 The Mersenne Twister PRNG implemented through the av_random* functions
1185 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1186 instead.
1187
1188 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1189 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1190 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1191 and av_fifo_realloc2.
1192 In addition, the order of the function arguments of av_fifo_generic_read
1193 was changed to match av_fifo_generic_write.
1194 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1195 applications, they may not use sizeof() or directly access members.
1196
1197 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1198 Introduce a new metadata API (see av_metadata_get() and friends).
1199 The old API is now deprecated and should not be used anymore. This especially
1200 includes the following structure fields:
1201 - AVFormatContext.title
1202 - AVFormatContext.author
1203 - AVFormatContext.copyright
1204 - AVFormatContext.comment
1205 - AVFormatContext.album
1206 - AVFormatContext.year
1207 - AVFormatContext.track
1208 - AVFormatContext.genre
1209 - AVStream.language
1210 - AVStream.filename
1211 - AVProgram.provider_name
1212 - AVProgram.name
1213 - AVChapter.title
