2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
534
  av_lockmgr_register() can be used to register a callback function
535
  that lavc (and in the future, libraries that depend on lavc) can use
536
  to implement mutexes. The application should provide a callback function
537
  that implements the AV_LOCK_* operations described in avcodec.h.
538
  When the lock manager is registered, FFmpeg is guaranteed to behave
539
  correctly in a multi-threaded application.
540

  The old decoding functions are deprecated, all new code should use the
550
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
551
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
552
  argument instead of a const uint8_t *buf / int buf_size pair.
553

    
554
2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

561
2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
562
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
563
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
564
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
565
  PIX_FMT_BGR32_1 are now macros.
566
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
567
  Re-sort the enum PixelFormat list accordingly.
568
  This change breaks API/ABI backward compatibility.
569

    
570
2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
571
  Add the enum PixelFormat values:
572
  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
573
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

576
  The Mersenne Twister PRNG implemented through the av_random* functions
577
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
578
  instead.
579

    
580
2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer
581
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
582
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
583
  and av_fifo_realloc2.
584
  In addition, the order of the function arguments of av_fifo_generic_read
585
  was changed to match av_fifo_generic_write.
586
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
587
  applications, they may not use sizeof() or directly access members.
588

    
589
2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
590
  Introduce a new metadata API (see av_metadata_get() and friends).
