567
  av_lockmgr_register() can be used to register a callback function
568
  that lavc (and in the future, libraries that depend on lavc) can use
569
  to implement mutexes. The application should provide a callback function
570
  that implements the AV_LOCK_* operations described in avcodec.h.
571

572
  correctly in a multi-threaded application.
573

  The old decoding functions are deprecated, all new code should use the
583
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
584
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
585
  argument instead of a const uint8_t *buf / int buf_size pair.
586

    
587
2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

594
2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
595
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
596
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
597
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
598
  PIX_FMT_BGR32_1 are now macros.
599
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
600
  Re-sort the enum PixelFormat list accordingly.
601
  This change breaks API/ABI backward compatibility.
602

    
603

  instead.

614
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
615
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
616
  and av_fifo_realloc2.
617
  In addition, the order of the function arguments of av_fifo_generic_read
618
  was changed to match av_fifo_generic_write.
619
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
620
  applications, they may not use sizeof() or directly access members.
621

    
622
2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
