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:
13 API changes, most recent first:
15 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
16 Move AVPacket declaration from libavformat/avformat.h to
19 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
20 Add the enum PixelFormat values:
21 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
22 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
24 2009-03-21 - r18116 - lavu 50.2.0 - av_random*
25 The Mersenne Twister PRNG implemented through the av_random* functions
26 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
30 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
31 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
32 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
34 In addition, the order of the function arguments of av_fifo_generic_read
35 were changed to match av_fifo_generic_write.
36 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
37 applications, they may not use sizeof() or directly access members.
39 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
40 Introduce a new metadata API (see av_metadata_get() and friends).
41 The old API is now deprecated and should not be used anymore. This especially
42 includes the following structure fields:
43 - AVFormatContext.title
44 - AVFormatContext.author
45 - AVFormatContext.copyright
46 - AVFormatContext.comment
47 - AVFormatContext.album
48 - AVFormatContext.year
49 - AVFormatContext.track
50 - AVFormatContext.genre
