2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
500
  av_lockmgr_register() can be used to register a callback function

503 227d1b98 Diego Biurrun
  that implements the AV_LOCK_* operations described in avcodec.h.
504
  When the lock manager is registered, FFmpeg is guaranteed to behave
505
  correctly in a multi-threaded application.

  new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
531
  PIX_FMT_BGR32_1 are now macros.
532
  avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
533 f3370e14 Stefano Sabatini
  Re-sort the enum PixelFormat list accordingly.
534 5a43bbc3 Stefano Sabatini
  This change breaks API/ABI backward compatibility.

548
  and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
549
  and av_fifo_realloc2.
550
  In addition, the order of the function arguments of av_fifo_generic_read
551 227d1b98 Diego Biurrun
  was changed to match av_fifo_generic_write.
552 889cdae8 Diego Biurrun
  The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
