  829.   that lavc (and in the future, libraries that depend on lavc) can use

  830.   to implement mutexes. The application should provide a callback function

  831.   that implements the AV_LOCK_* operations described in avcodec.h.

  832.   When the lock manager is registered, FFmpeg is guaranteed to behave

  833.   correctly in a multi-threaded application.

  834.

  844.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  845.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  846.   argument instead of a const uint8_t *buf / int buf_size pair.

  847. 

  848. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

  854. 

  855. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats

  856.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  857.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  858.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  859.   PIX_FMT_BGR32_1 are now macros.

  860.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  861.   Re-sort the enum PixelFormat list accordingly.

  862.   This change breaks API/ABI backward compatibility.

  863. 

  864. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  865.   Add the enum PixelFormat values:

  866.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  867.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  868. 

  869. 2009-03-21 - r18116 - lavu 50.0.0  - av_random*

  870.   The Mersenne Twister PRNG implemented through the av_random* functions

  871.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  872.   instead.

  873. 

  874. 2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  875.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  876.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  877.   and av_fifo_realloc2.

  878.   In addition, the order of the function arguments of av_fifo_generic_read

  879.   was changed to match av_fifo_generic_write.

  880.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  881.   applications, they may not use sizeof() or directly access members.

  882. 

  883. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

  884.   Introduce a new metadata API (see av_metadata_get() and friends).

  885.   The old API is now deprecated and should not be used anymore. This especially

  886.   includes the following structure fields:
