13 API changes, most recent first:
14
15 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space
16 Introduce the av_fifo_space() function.
17
18 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
19 Move AVPacket declaration from libavformat/avformat.h to
20 libavcodec/avcodec.h.

22 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
23 Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
24 PIX_FMT_BGRA, which were defined as macros, defined as enum
25 PixelFormat values, and viceversa make PIX_FMT_RGB32,
26 PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
27 Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
28 aliases.
29 Re-sort the enum PixelFormat list accordingly.
30 This change breaks API/ABI backward compatibility.
31
32 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
33 Add the enum PixelFormat values:
34 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
35 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
36
37 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
38 The Mersenne Twister PRNG implemented through the av_random* functions
39 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
40 instead.
41
42 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
43 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
44 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
45 and av_fifo_realloc2.
46 In addition, the order of the function arguments of av_fifo_generic_read
47 were changed to match av_fifo_generic_write.
48 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
49 applications, they may not use sizeof() or directly access members.
50
51 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

57 - AVFormatContext.copyright
58 - AVFormatContext.comment
59 - AVFormatContext.album
60 - AVFormatContext.year
61 - AVFormatContext.track
62 - AVFormatContext.genre
63 - AVStream.language
64 - AVStream.filename
65 - AVProgram.provider_name
66 - AVProgram.name
67 - AVChapter.title
