2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
585

2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
589
  av_lockmgr_register() can be used to register a callback function
590
  that lavc (and in the future, libraries that depend on lavc) can use
591
  to implement mutexes. The application should provide a callback function
592
  that implements the AV_LOCK_* operations described in avcodec.h.
593
  When the lock manager is registered, FFmpeg is guaranteed to behave
594
  correctly in a multi-threaded application.
595

  The old decoding functions are deprecated, all new code should use the
605
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
606
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
607
  argument instead of a const uint8_t *buf / int buf_size pair.
608

    
609
2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

616
2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
617
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
618
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
619
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
620
  PIX_FMT_BGR32_1 are now macros.
621
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
622
  Re-sort the enum PixelFormat list accordingly.
623
  This change breaks API/ABI backward compatibility.
624

    
625
2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
626
  Add the enum PixelFormat values:
627
  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
628
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

631

632
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
633
  instead.
634

    
635
2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer
636
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
637
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
638
  and av_fifo_realloc2.
639
  In addition, the order of the function arguments of av_fifo_generic_read
640
  was changed to match av_fifo_generic_write.
641
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
642
  applications, they may not use sizeof() or directly access members.
643

    
644
2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
645
  Introduce a new metadata API (see av_metadata_get() and friends).
