  412. av_lockmgr_register() can be used to register a callback function
  413. that lavc (and in the future, libraries that depend on lavc) can use
  414. to implement mutexes. The application should provide a callback function
  415. that implements the AV_LOCK_* operations described in avcodec.h.
  416. When the lock manager is registered, FFmpeg is guaranteed to behave
  417. correctly in a multi-threaded application.
  418. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()

  424. The old decoding functions are deprecated, all new code should use the
  425. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  426. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  427. argument instead of a const uint8_t *buf / int buf_size pair.
  428. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
  429. Introduce the av_fifo_space() function.

  434. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  435. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  436. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  437. PIX_FMT_BGR32_1 are now macros.
  438. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  439. Re-sort the enum PixelFormat list accordingly.
  440. This change breaks API/ABI backward compatibility.
  441. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  442. Add the enum PixelFormat values:

  444. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  445. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  446. The Mersenne Twister PRNG implemented through the av_random* functions
  447. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  448. instead.
  449. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  450. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  451. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  452. and av_fifo_realloc2.
  453. In addition, the order of the function arguments of av_fifo_generic_read
  454. was changed to match av_fifo_generic_write.
  455. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  456. applications, they may not use sizeof() or directly access members.
  457. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  458. Introduce a new metadata API (see av_metadata_get() and friends).
  459. The old API is now deprecated and should not be used anymore. This especially
  460. includes the following structure fields:
  461. - AVFormatContext.title
  462. - AVFormatContext.author
  463. - AVFormatContext.copyright
  464. - AVFormatContext.comment
  465. - AVFormatContext.album
  466. - AVFormatContext.year
