  740. av_lockmgr_register() can be used to register a callback function
  741. that lavc (and in the future, libraries that depend on lavc) can use
  742. to implement mutexes. The application should provide a callback function
  743. that implements the AV_LOCK_* operations described in avcodec.h.
  744. When the lock manager is registered, FFmpeg is guaranteed to behave
  745. correctly in a multi-threaded application.

  752. The old decoding functions are deprecated, all new code should use the
  753. new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  755. argument instead of a const uint8_t *buf / int buf_size pair.
  756. 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

  762. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  763. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  764. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  765. PIX_FMT_BGR32_1 are now macros.
  766. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  767. Re-sort the enum PixelFormat list accordingly.
  768. This change breaks API/ABI backward compatibility.
  769. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  770. Add the enum PixelFormat values:

  772. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  773. 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
  774. The Mersenne Twister PRNG implemented through the av_random* functions
  775. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  776. instead.

  778. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  779. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  780. and av_fifo_realloc2.
  781. In addition, the order of the function arguments of av_fifo_generic_read
  782. was changed to match av_fifo_generic_write.
  783. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  784. applications, they may not use sizeof() or directly access members.
  785. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
  786. Introduce a new metadata API (see av_metadata_get() and friends).
  787. The old API is now deprecated and should not be used anymore. This especially
  788. includes the following structure fields:
  789. - AVFormatContext.title
  790. - AVFormatContext.author
  791. - AVFormatContext.copyright
  792. - AVFormatContext.comment
