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:

23 Add the enum PixelFormat values:
24 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
25 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
27 2009-03-21 - r18116 - lavu 50.2.0 - av_random*

37 In addition, the order of the function arguments of av_fifo_generic_read
38 were changed to match av_fifo_generic_write.
39 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
