14 API changes, most recent first:
15
16 2012-xx-xx - xxxxxxx - lavu 52.2.0 - audioconvert.h
17 Rename audioconvert.h to channel_layout.h. audioconvert.h is now deprecated.
18
19 2012-xx-xx - xxxxxxx - lavu 52.1.0 - intmath.h
20 Add av_ctz() for trailing zero bit count
21
22 2012-10-18 - xxxxxxx - lavu 51.45.0 - error.h
23 Add AVERROR_EXPERIMENTAL
24
25 2012-10-12 - xxxxxxx - lavu 51.44.0 - pixdesc.h
26 Add functions for accessing pixel format descriptors.
27 Accessing the av_pix_fmt_descriptors array directly is now
28 deprecated.
29
30 2012-10-xx - xxxxxxx - lavu 51.43.0 - aes.h, md5.h, sha.h, tree.h
31 Add functions for allocating the opaque contexts for the algorithms,
32 deprecate the context size variables.
33
34 2012-10-xx - xxxxxxx - lavf 54.18.0 - avio.h
35 Add avio_closep to complement avio_close.
36
37 2012-10-xx - xxxxxxx - lavu 51.42.0 - pixfmt.h
38 Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
39 To provide backwards compatibility, PixelFormat is now #defined as
40 AVPixelFormat.
41 Note that this can break user code that includes pixfmt.h and uses the
42 'PixelFormat' identifier. Such code should either #undef PixelFormat
43 or stop using the PixelFormat name.
44
45 2012-10-05 - e7ba5b1 - lavr 1.0.0 - avresample.h
46 Data planes parameters to avresample_convert() and
47 avresample_read() are now uint8_t** instead of void**.
48 Libavresample is now stable.
49
50 2012-09-24 - a42aada - lavc 54.28.0 - avcodec.h
51 Add avcodec_free_frame(). This function must now
52 be used for freeing an AVFrame.

62 Add codec descriptor properties AV_CODEC_PROP_LOSSY and
63 AV_CODEC_PROP_LOSSLESS.
64
65 2012-08-18 - lavc 54.26 - avcodec.h
66 Add codec descriptors for accessing codec properties without having
67 to refer to a specific decoder or encoder.
68
69 c223d79 - Add an AVCodecDescriptor struct and functions
70 avcodec_descriptor_get() and avcodec_descriptor_next().
71 51efed1 - Add AVCodecDescriptor.props and AV_CODEC_PROP_INTRA_ONLY.
72 91e59fe - Add avcodec_descriptor_get_by_name().
73

79 Add av_dict_count().
80
81 2012-08-07 - 104e10f - lavc 54.25 - avcodec.h
82 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
83 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
84 Note that this can break user code that includes avcodec.h and uses the
85 'CodecID' identifier. Such code should either #undef CodecID or stop using the
86 CodecID name.
87
88 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h
89 lsws 2.1.1 - swscale.h

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

261 e1d9dbf Add a new installed header - buffersrc.h
262 It contains a new function av_buffersrc_buffer() that allows passing
263 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
264 it allows for direct rendering.
265 1c9e340 Add avfilter_copy_frame_props() for copying properties from
266 AVFrame to AVFilterBufferRef.
267
268 2011-12-25 - lavc 53.31.0

285 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
286 audio decoders to use get_buffer().
287
288 2011-12-04 - 560f773 - lavc 53.24.0
289 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

303 which is accessed from a new field, AVCodecContext.internal.
304 - fields moved:
305 AVCodecContext.internal_buffer --> AVCodecInternal.buffer
306 AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
307 AVCodecContext.is_copy --> AVCodecInternal.is_copy
308
309 2011-11-16 - 6270671 - lavu 51.16.0
310 Add av_timegm()
311
312 2011-11-13 - lavf 53.15.0

315 6aa0b98 Add AVIOInterruptCB struct and the interrupt_callback field to
316 AVFormatContext.
317 1dee0ac Add avio_open2() with additional parameters. Those are
318 an interrupt callback and an options AVDictionary.

1172 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1173 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1174 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1175 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1176 PIX_FMT_BGR32_1 are now macros.
1177 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1178 Re-sort the enum PixelFormat list accordingly.
1179 This change breaks API/ABI backward compatibility.
1180
1181 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1182 Add the enum PixelFormat values:
1183 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1184 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

1186 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1187 The Mersenne Twister PRNG implemented through the av_random* functions
1188 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1189 instead.

1191 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1192 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1193 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1194 and av_fifo_realloc2.
1195 In addition, the order of the function arguments of av_fifo_generic_read
1196 was changed to match av_fifo_generic_write.
1197 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1198 applications, they may not use sizeof() or directly access members.

1200 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1201 Introduce a new metadata API (see av_metadata_get() and friends).
1202 The old API is now deprecated and should not be used anymore. This especially
1203 includes the following structure fields:
1204 - AVFormatContext.title
1205 - AVFormatContext.author
1206 - AVFormatContext.copyright
1207 - AVFormatContext.comment
1208 - AVFormatContext.album
1209 - AVFormatContext.year
1210 - AVFormatContext.track
1211 - AVFormatContext.genre
1212 - AVStream.language
1213 - AVStream.filename
1214 - AVProgram.provider_name
1215 - AVProgram.name
1216 - AVChapter.title
