  1493. that implements the AV_LOCK_* operations described in avcodec.h.
  1494. When the lock manager is registered, FFmpeg is guaranteed to behave
  1495. correctly in a multi-threaded application.

  1503. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  1504. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  1505. argument instead of a const uint8_t *buf / int buf_size pair.
  1506. 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

  1512. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  1513. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  1514. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  1515. PIX_FMT_BGR32_1 are now macros.
  1516. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  1517. Re-sort the enum PixelFormat list accordingly.
  1518. This change breaks API/ABI backward compatibility.
  1519. 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  1520. Add the enum PixelFormat values:

  1522. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  1523. 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
  1524. The Mersenne Twister PRNG implemented through the av_random* functions
  1525. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  1529. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  1530. and av_fifo_realloc2.
  1531. In addition, the order of the function arguments of av_fifo_generic_read
  1532. was changed to match av_fifo_generic_write.
  1533. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  1534. applications, they may not use sizeof() or directly access members.
  1535. 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
  1536. Introduce a new metadata API (see av_metadata_get() and friends).
  1537. The old API is now deprecated and should not be used anymore. This especially
  1538. includes the following structure fields:
  1539. - AVFormatContext.title
