902009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
91 av_lockmgr_register() can be used to register a callback function
92 that lavc (and in the future, libraries that depend on lavc) can use
93 to implement mutexes. The application should provide a callback function
94 the implements the AV_LOCK_* operations described in avcodec.h.
95 When the lock manager is registered FFmpeg is guaranteed to behave
96 correct also in a multi-threaded application.

1052009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
106 The old decoding functions are deprecated, all new code should use the
107 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
108 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
109 argument instead of a const uint8_t *buf / int buf_size pair.

1182009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
119 Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
120 PIX_FMT_BGRA, which were defined as macros, defined as enum
121 PixelFormat values, and viceversa make PIX_FMT_RGB32,
122 PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
123 Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
124 aliases.
f3370e14 125 Re-sort the enum PixelFormat list accordingly.

134 The Mersenne Twister PRNG implemented through the av_random* functions
135 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
136 instead.

1382009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
139 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
140 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
141 and av_fifo_realloc2.
142 In addition, the order of the function arguments of av_fifo_generic_read
143 were changed to match av_fifo_generic_write.
144 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
145 applications, they may not use sizeof() or directly access members.
