772009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
78 av_lockmgr_register() can be used to register a callback function
79 that lavc (and in the future, libraries that depend on lavc) can use
80 to implement mutexes. The application should provide a callback function
81 the implements the AV_LOCK_* operations described in avcodec.h.
82 When the lock manager is registered FFmpeg is guaranteed to behave
83 correct also in a multi-threaded application.

93 The old decoding functions are deprecated, all new code should use the

95 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
96 argument instead of a const uint8_t *buf / int buf_size pair.

1052009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
106 Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
107 PIX_FMT_BGRA, which were defined as macros, defined as enum
108 PixelFormat values, and viceversa make PIX_FMT_RGB32,
109 PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
110 Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
111 aliases.
f3370e14 112 Re-sort the enum PixelFormat list accordingly.

121 The Mersenne Twister PRNG implemented through the av_random* functions
122 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
123 instead.

1252009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
126 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
127 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
128 and av_fifo_realloc2.
129 In addition, the order of the function arguments of av_fifo_generic_read
130 were changed to match av_fifo_generic_write.
131 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
132 applications, they may not use sizeof() or directly access members.
