656 227d1b98 Diego Biurrun
  Add a pts field to AVSubtitle which gives the subtitle packet pts
657
  in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will

664 f988ce6c Andreas Öman
2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
665
  av_lockmgr_register() can be used to register a callback function
666
  that lavc (and in the future, libraries that depend on lavc) can use
667
  to implement mutexes. The application should provide a callback function
668 227d1b98 Diego Biurrun
  that implements the AV_LOCK_* operations described in avcodec.h.
669
  When the lock manager is registered, FFmpeg is guaranteed to behave
670
  correctly in a multi-threaded application.

2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
680
  The old decoding functions are deprecated, all new code should use the
681
  new functions avcodec_decode_video2(), avcodec_decode_audio3() and
682
  avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
683
  argument instead of a const uint8_t *buf / int buf_size pair.

2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
693 227d1b98 Diego Biurrun
  Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
694
  PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
695
  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
696
  PIX_FMT_BGR32_1 are now macros.
697
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
698 f3370e14 Stefano Sabatini
  Re-sort the enum PixelFormat list accordingly.
699 5a43bbc3 Stefano Sabatini
  This change breaks API/ABI backward compatibility.

  PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
704
  PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

707 c8f742ca Diego Biurrun
  The Mersenne Twister PRNG implemented through the av_random* functions
708
  was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
709
  instead.

711 889cdae8 Diego Biurrun
2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer
712
  av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
713
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
714
  and av_fifo_realloc2.
715
  In addition, the order of the function arguments of av_fifo_generic_read
716 227d1b98 Diego Biurrun
  was changed to match av_fifo_generic_write.
717 889cdae8 Diego Biurrun
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
718
  applications, they may not use sizeof() or directly access members.
